Thomas Edison

A History of Recorded Sound, Part Two


The phonograph was the first invention of substance to come out of Thomas Edison's Menlo Park invention factory. Of the 1,093 inventions credited to him, it was his favorite and would remain so for the rest of his life.

The creation of the phonograph was one of those technological breakthroughs where everything fell neatly into place, as opposed to Edison's trials and tribulations with the incandescent lamp for which he painstakingly tested thousands of different materials before finding the right one. About the incandescent ordeal he later recalled, "Before I got through I tested no fewer than 6,000 vegetable growths, and ransacked the world for the most suitable filament material."

Even before December 24, 1877, when he applied for a patent on his talking machine, Edison was busily promoting his machine. The December 22, 1877 edition of Scientific American documented the inventor's recent visit to the magazine's New York City offices:

"Mr. Thomas A Edison recently came into this office, placed a little machine on our desk, turned a crank, and the machine inquired as to our health, asked how we liked the phonograph, informed us that it was very well, and bid us a cordial good night."

The event was covered by newspapers in the city, and in short order by those in other parts of the country.

The Edison Speaking Phonograph Company was established on January 24, 1878 to capitalize on the public's fascination with the machine. He received $10,000 for the manufacturing and sales rights, and 20-percent of the profits.

In the June 1878 edition of North American Review, Edison offered 10 suggested uses for the phonograph (see previous installment). By that time, however, the novelty of the talking machine had seemingly peaked, and Edison left promotional efforts to others, while he turned his attention to the incandescent light bulb.

In the meantime, others, among them Alexander Graham Bell, became involved. Where Edison considered his phonograph state of the art, Bell and others saw room for improvement. In fact, while Edison's device was a big hit with the public, it was hard to operate, the foil recording medium was easily torn, and had a short, useable life.

Into The Breach

Nature abhors a vacuum, and so the void created by Edison's diversion from the sound field was soon filled by others, Charles Sumner Tainter (1854-1940) was among the first.

Tainter was an engineer and inventor, an avocation he may have picked up from his father, the inventor of an automatic wood-boring tool. Although he attended public schools, he was largely self-taught from technical journals at the public library and from his father's subscription to Scientific American. After establishing a scientific instrument manufacturing business in his hometown of Watertown MA in 1878, Tainter became acquainted with Alexander Graham Bell, who was a customer for whom he made electrical devices.  
                                             
Charles Tainter 
In 1879, Tainter accepted Bell's invitation to relocate to Washington, D.C. to establish a laboratory and work with him on the development of sound-based technologies. The following year, Bell and Tainter developed the Radiophone, a device that used light waves and selenium cells (a mineral having semiconducting properties) to transmit sound wirelessly. Their efforts were rewarded with a gold medal at the 1881 Electrical Exhibition in Paris.

Meanwhile in 1881 in D.C., the pair were joined by a first cousin of Bell's with a truly tongue twister of a name, Chichester A. Bell. The newly arrived Bell – a noted London-based chemist – had come for the expressed purpose of producing an improved phonograph that would be called the "Graphophone", an obvious play on the name of Edison's invention. Their partnership, which became known as the Volta Lab, was financed from the 40,000 French franc prize money won by Alexander for his telephone invention in 1876.

Charles Tainter and his two partners initially set out to improve Edison's tin foil recording and playback medium. They achieved initial success with a flexible foil before discarding it in favor of wax when their work was interrupted by the assassination of President James A. Garfield by Charles Guiteau. Attention in the lab was abruptly shifted from the Graphophone to efforts to create an improved audible induction balance device (an early type of metal detector) in a frantic but futile attempt to devise a way to find the assassin’s bullet and save the President's life.

Once work on the Graphophone resumed, Bell and company eventually perfected their wax recording and playback medium with the addition of carnauba wax to improve its durability and decrease surface noise caused by the stylus rubbing against the inside of the groove.

Continued research led first to the introduction of the Dictaphone – the name of a much-respected brand that has survived into the 21st century, even as the once ubiquitous business product of the same name has largely been edged out by newer technologies and products – then to the Graphophone, itself.

The Bells and Tainter's efforts to market the Graphophone were initially blocked by Edison's unsuccessful challenge to the validity of their patent. Later when approached about joining forces with the Volta Lab team to jointly produce a phonograph that incorporated the best qualities of their respective inventions into a single device, Edison refused, determined to improve the Phonograph on his own.

The Volta Graphophone Company was created in January 1886 to control the patents and commercial development of Tainter's and the two Bell's sound recording and reproduction technologies, the first of which was issued in 1887. At that time, the Volta Graphophone Company became the American Graphophone Company, which would evolve into Columbia Records, which would later become part of Sony.

The Columbia Phonograph Co. was organized on January 15, 1889 by Edward D. Easton "with rights to market a treadle-powered graphophone. Easton, however, would have more success selling music than business machines, especially cylinders of the popular United States Marine Band under the direction of John Philip Sousa. Easton produced the first record catalog in 1890. It was a one-page listing of available Edison and Columbia cylinders.

At Menlo Park, Edison's efforts to market his phonograph as a business machine were similarly unsuccessful. He, too, shifted his focus to entertainment, selling pre-recorded cylinders of popular music. These embryonic marketing efforts would transform the music business – an unorganized conglomeration of performers, songwriters, publishers, and theater owners – from little more than a cottage industry into a multinational behemoth in the century to come.

Another Voice Heard From

The third major player in the sound recording/reproduction game would produce a device that would prove to be the most significant variant of the "talking machines".

Emile Berliner (1851-1929) was born into a family of Jewish merchants in Hanover, Germany. Although he did follow family tradition by completing an apprenticeship as a merchant, his real passion was inventing, while he worked as an accountant to make ends meet. He migrated to the United States in 1870 to avoid being drafted into service during the Franco-Prussian War.


In the US, Berliner performed a succession of menial jobs while attending physics classes at night at Cooper Union Institute in New York City. He soon found himself attracted to the newly emerging field of audio technologies, Bell's telephone and Edison's phonograph in particular.

His earliest efforts led to a patent in 1885 for an early type of microphone that was picked up by the Bell Telephone Company for use as an improved telephone transmitter. The following year Berliner received a patent for the "Gramophone", a sound recording and playback device.

Like Edison's phonograph, and the Volta Lab's graphophone, Berliner's first gramophone employed a wax-coated cylinder. But while Berliner employed means similar to his predecessors/competitors to achieve results, he recognized the cylinder's inherent disadvantages, and realized its wax medium was too soft and fragile for permanent recordings. He focused his attention on developing more durable mediums.

Gramophones produced after 1888 discarded cylinders in favor of techniques used by Leon Scott's Phonautograph. These later machines used discs on spinning turntables, and so more closely resembled the record players and turntables familiar to people today. Discs were made initially of celluloid, then of harder, vulcanized rubber. Recordings were created on a master disc made of zinc. Sound was funneled through a horn, which transferred it to a stylus, which in turn, etched the sound signal onto the master. The etched master disc was then reproduced on playback discs in a process that would be readily understood by people today.

By 1893, Berliner had sold 1000 machines, and with continual improvements and tweaks, his gramophone would exert increasing influence over consumers.

Berliner's significance was emphasized by a conspicuous lack of    
1895 Gramophone
standardization in the early years of the field of sound recording and reproduction. Thomas Edison has justly received his share of kudos as the inventor of the phonograph – the record player. Edison, however, was far more interested in doing whatever was necessary to make his device work than he was with incidental matters such as stylus materials, the size of the groove, and playback speed. On the other hand, Berliner, like Charles Tainter, Alexander and Chichester Bell, set out to make a better mousetrap, not invent it. He was able to focus on individual components.

For example, Edison employed a jewel for his stylus. Berliner used the points of steel sewing needles and pins, which were obviously of a more uniform size and less expensive. The use of steel styluses allowed him to determine a consistent size and depth of grooves, which in turn, allowed him to determine that a turntable speed in the range of 70-90 rpm produced the best listening results.

Not being one to rest on his laurels, Berliner would carry on with his tinkering and experimentation for the rest of his life. He continued to invent things including, in 1910, an early version of a helicopter. In 1901, Berliner with Elbridge Johnson (1867-195) founded the Victor Talking Machine Company, which in 1929 would be acquired by the Radio Corporation of America, or RCA. "His Master's Voice," the company's logo is a licensed reproduction of the painting of the same name by English artist Francis Barraud. The painting depicts Nipper, a fox terrier reacting to a recording of the voice of his dead master Mark Barraud (the artist's brother) played back on a gramophone.

By the turn of the twentieth century, the technology that would enable the music entertainment industry to grow prosperous beyond anyone's previous expectations was firmly established. And like all emerging technologies, the foundational work of Thomas Edison, Charles Tainter, Alexander, and Chichester Bell, and Emile Berliner was improved upon by countless supplemental developments and discoveries.

A small sampling of those supplemental developments included:

Shellac (a resin secreted by the female lac bug, a native of forested regions of Asia) replaced vulcanite as a source material for recorded discs in 1897. The relatively heavy 9-ounces of a typical steel stylus used on most playback equipment, however, continued to cause heavy wear. On the other hand, the rapidly growing number of new, low-cost and reliable machines such as the Columbia Eagle Graphophone, the Edison Gem Cylinder Phonograph, and Berliner's improved Gramophone spurred strong sales of commercial cylinders and discs primarily classical works, and "Tin Pan Alley" songs.

A case in point about costs is the Edison phonograph. A typical consumer paid $150 for one in 1891, the equivalent of paying $3,750 in 2012. By 1898, the cost of an Edison cylinder machine had dropped to $20, or the 2012 equivalent of $555.

In 1898, Valdemar Poulsen, the son of a Danish High court judge, patented the "Telegraphone", a method of, and apparatus for, effecting the storing up of speech or signals by magnetically influencing magnetisable bodies"… the first magnetic recorder. Poulsen's device used steel wire as a recording medium, making him the father of the aircraft flight recorder, or "black box", the reel-to-reel tape recorder, 8-track tape player, and compact cassette. The American patent of Poulsen's device, #661,619, was validated in 1903.

In 1900, Thomas Lambert developed the technology to mass-produce indestructible celluloid cylinders. "Indestructible," in his usage was not a testament of the durability of the playing surface of discs and cylinders, but a reference to the surface medium’s ability to capture a greater range of frequencies.

Unfortunately for Lambert – whose patent, #645,920, was validated by US courts – he ran afoul of Thomas Edison, possibly because the Menlo Park Wizard objected to the use of the word "phonograph" in the name of Lambert's company, Indestructible Phonograph Record Company. Edison used the courts to drive Lambert out of business by 1907. Still, Lambert's method of making a "copper negative matrix by electrolysis" from a wax master, and using heat and pressure to mold "durable celluloid copies" is a close enough approximation of the process used to manufacture vinyl records today.

Of Talking Machines And Wizards: The History of Recorded Sound, Part One


Of Talking Machines And Wizards

     by Michael Daisy




The title of this piece (the first of three parts) introduces its subject as a history of recorded sound, rather than music or anything entertainment-related. That's intentional. Like most people, you probably consider recording and music or musical entertainment two sides of the same coin That, however, is not how it started out.

For the record, this is an overview. It is intended to be neither complete nor comprehensive. There is far too much information out there to cover everything in this setting. It is not THE history of recorded sound. It is A history of recorded sound.


A History of Recorded Sound, Part One

In the June 1878 edition of North American Review magazine, Thomas Edison listed "Reproduction of Music" as one suggested use of his new phonograph invention. It was number four of 10. The three above it were:

1. "Letter writing and all kinds of dictation without the aid of a stenographer,"
2. "Phonographic books, which will speak to blind people without effort on their part," and
3. "The teaching of elocution."

Consider Columbia Records, a gigantic, multi-tentacled media concern. It lords over countless smaller record labels, and has a stable of best-selling recording artists that include the likes of Barbra Streisand, Tony Bennett, Mariah Carey, and Bob Dylan.

While it was the first company to sell recorded music (on cylinders), it started out as a manufacturer of business machines, and distributor of Edison phonographs.

It should come as no surprise, then, that the oldest surviving recordings are of the spoken word variety.

Speaking of Edison… Most people are aware that it was Thomas Edison who invented the phonograph. It was, in fact, his favorite of the many inventions credited to him. But mention the names of similar and related devices, such as the Phonautograph, Peleophone, and Graphophone and, most likely, you'll get a puzzled look in response.

There is no question of the importance of Edison's contributions to sound recording. However, he didn't do it alone, nor was he working in a vacuum when the breakthrough occurred.

Ancient Foundations

Creation of sound by artificial or mechanical means has been around for thousands of years. The drum was a natural outgrowth of man's love of beating on things and making noise. The didgeridoo (or didjeridu, if you prefer) is the oldest known wind instrument. It has been used for thousands of years by the aboriginal peoples of Australia.

A noteworthy example of a sound-producing device, is, or rather, was, the Colossi of Memnon, a pair of stone statues located along the Nile opposite the City of Luxor in Egypt.


It’s a bit of a stretch to link these stone beings to luminaries like Thomas Edison, but some distinguished centers of higher learning do. And so, to paraphrase Gene Lockhart's Judge Henry X. Harper in the holiday classic Miracle on 34th Street, 'if established centers of higher learning see fit to consider the Colossus a precursor to the phonograph and compact disc, this writer will not disagree.' The ability to charge tuition for your interpretation of things tends to generate its own credibility.

And so without further ado, the Colossi. Actually, we are concerned only with one of the pair.

The Colossi were constructed from blocks of quartzite sandstone during the reign of Amenhotep III in the 15th century BCE (Before Common Era). The twin giants originally served as guards at the entrance of Amenhotep's memorial temple, a massive complex where the pharaoh was worshipped as a god during his lifetime and after.

The twin depictions of a seated Amenhotep stood as silent sentinels for well over a thousand years until the temple was destroyed in a devastating earthquake in 27 BCE. The quake collapsed one of the statues from the waist up.

At the time of the quake, Egypt was in the twilight of the period of Hellenistic Ptolemaic rule. It wasn't long after the quake subsided that the partially collapsed Colossi became associated with Memnon, the Greek hero killed at Troy as he greeted his mother, Aurora, goddess of the dawn.

Accordingly at dawn, the statue would sing, a sound that has been described as a whistle, a bell, a low moan, or a plucked harp string. It is believed the "vocalizations" resulted from the heating and expansion of the stone by rays of the morning sun interacting with cooler air within the cracks and crevices of the statue’s interior.

Hearing the statue sing was supposed to bring good luck. The "Vocal Memnon" drew visitors from throughout the known world. They came to hear the statue and experience the oracular powers it apparently picked up along the way.

The singing ended abruptly in the year 199 when the Roman Emperor of the time, Septimius Severus (146-211), reassembled the statue in an effort to gain favor with the oracle. Apparently, the goddess Aurora didn't consider the Emperor's gesture worth considering.

A seemingly endless array of devices able to reproduce sound by mechanical means -- organs, carillons, music boxes, and other marvels -- would appear over the course of succeeding centuries. But it wasn't until the 19th century that devices capable of reproducing recorded sound made their appearance.

Before Edison

Around 1806, English physician and naturalist Thomas Young reportedly created a visual image of a tuning fork's vibrations in the wax covering of a rotating cylinder. He was able to use the image to measure minute increments of time by using a known frequency.

Roughly a half-century later, on March 25, 1857, the French government granted Edourd-Leon Scott de Martinville a patent (#17,897/31,470) for a device he called a Phonautograph that created visual images of sound waves.

Scott's phonautograph looks immediately familiar to anyone who has seen images of Edison's phonograph. It should since both machines operate on the same basic principles.

Scott (1817-79) was a printer, librarian, bookseller, and inventor. Though he had French royal blood flowing through his veins, his family lacked the money to live in a style they would undoubtedly have enjoyed in an earlier, more opulent time. Denied the opportunity to pursue a life of idle indulgence, the young Scott embarked upon a career as a printer's apprentice.

At the stage of his training where he was tasked with reading and correcting proofs, Scott immersed himself in the manuscripts he encountered. He subsequently sought out and engaged many of the learned authors in conversation. This, in turn, influenced his decision to invent.

A small sampling of those who inspired Scott are Henri Victor Regnault (1817-78), best known for measuring the thermal properties of gas; Jean Baptiste Biot (1774-1862), a physicist, astronomer and mathematician who ascended in a hot air balloon to study the Earth's atmosphere; and Andre-Marie Ampere (1775-1836), a physicist given primary credit for discovering electromagnetism.

Phonautograph

Scott used the anatomy of the human ear as a basis for the phonautograph. Sound to be recorded was funneled through a horn to a diaphragm that vibrated. A hog's bristle was attached to the diaphragm.

The bristle in the 1857 version of his recorder etched a pattern on a lamp-blacked glass plate. Two years later he incorporated lamp-blacked paper attached to a rotating cylinder to capture images of the sound.

The phonautograph could only reproduce images of the sound it recorded. In any event, reproducing recordings was never part of the plan. Scott was trying to create a type of oral shorthand.

Scott attempted to market his invention, and even succeeded in producing a few devices with the help of Rudolf Koenig, a German manufacturer of musical instruments. He made the odd sale or two – including one to Joseph Henry for the Smithsonian Institution in 1866 – but he never reached the point where he was able to give up his day job.

For all intents and purposes, the phonautograph was a dismal failure. It was a well-executed device based on a faulty premise. Although his early sound etchings were digitally scanned and played back for the first time as sound recordings in 2008, it was more than a century too late. Scott died poor on April 26, 1879, without ever having developed the oral shorthand his machine was supposed to facilitate.

Though Scott fell short of his goal, his work was not in vain. Roughly 20 years after the phonautograph was patented, another Frenchman took the next logical step in sound recording

Inspired Lunacy

Charles Cros (1842-1888) was an inventor, poet, humorous writer, and an excellent example of the fine line between genius and insanity. He invented a number of improvements in the field of photography, including an early process for color photography. He is also responsible for several improvements to telegraph technology.

Charles Cros
On the other hand, he believed pinpoints of light he observed on the surfaces of Venus and Mars were produced by the lights of large cities. They were most likely the result of the reflected light of the Sun from high clouds. Nevertheless, Cros spent years petitioning the French government to build a giant mirror capable of communicating with the Martians.

He went to his grave absolutely convinced of the existence of life on Mars, and unaware of the technical impossibility of his mirror.

On a more down to earth level in 1877, Cros almost beat Edison to the punch on sound recording. Almost.

In a letter to the Academy of Sciences in Paris dated April 30 of that year, Cross proposed recording and playing back sound on a device very similar to Scott's phonautograph. Cros called his device a Paleophone.

The device incorporated a cylinder on which the vibrations of the sound recorded were etched by a screw into a metal surface for durability's sake. He suggested the possibility of reproducing the original sound by retracing the pattern.

Similarities between Cros' proposal and what Edison was doing at the time were remarkable considering neither was aware of what the other was doing. Unfortunately for Cros, the paleophone was only an idea. He didn't have a working model.

Cros' letter was read in public on December 3, 1877. A scholarly article written by l'Abbe' Leblanc was published in the journal La Semaine du Clerge on October 10, 1878. Of course, by then it was too late.

The Father of Voice Mail

According to various accounts, Thomas Edison was engaged in work involving the telegraph and telephone in 1877 when he was struck by the inspiration for the Phonograph.

He was working on a machine capable of transcribing telegraphic messages as indentations on paper tape that could be used to send the same message repeatedly. This led him to consider the possibility of repeatedly sending voice messages by means of the telephone invented only the previous year by Alexander Graham Bell. It was a small step from there to the phonograph.

Edison's first phonograph was based on his telegraphic repeater. It incorporated two diaphragms and a metal cylinder covered with paraffin paper. One diaphragm was used for recording, the other for playback. Sometime before December, the recording medium was switched to tin foil.

Edison made a drawing from which his mechanic, John Kruesi built the machine between December 1-6, 1877. It was on the 6th that Edison made and heard his historic recording of "Mary had a little lamb."

It is speculated that Edison recorded the word "Halloo" on paper with his telegraphic repeater in July. Regardless, neither recording survives, and anyone having any connection has long since passed into history.

The Wizard of Menlo Park recreated the "Mary had a little lamb" recording on August 12, 1927 to commemorate the 50th anniversary of the event. It was captured for a Fox Movietown Newsreel at Edison's home in West Orange, New Jersey.

Edison applied for the American patent for his talking machine on Christmas Eve, 1877. Patent number 200,521 was granted on February 19, 1878.

The world's oldest surviving sound recording is a recitation of "The Lord's Prayer" by Emile Berliner. The recording was made on an Edison cylinder machine. It is currently in the possession of the BBC in London, England.


 Postscript
Possible future uses for the phonograph suggested by Thomas Edison in North American Review, June 1878:

1. Letter writing and all kinds of dictation without the aid of a stenographer.
2. Phonographic books, which will speak to blind people without effort on their part.
3. The teaching of elocution.
4. Reproduction of music.
5. The "Family Record" – a registry of sayings, reminiscences, etc., by members of a family in their own voices, and of the last words of dying persons.
6. Music-boxes and toys.
7. Clocks that should announce in articulate speech the time for going home, going to meals, etc.
8. The preservation of languages by exact reproduction of the manner of pronouncing.
9. Educational purposes: such as preserving the explanations made by a teacher, so that a pupil can refer to them at any moment, and spelling or other lessons placed upon the phonograph for convenience in committing to memory.
10. Connection with the telephone, so as to make that instrument an auxiliary in the transmission of permanent and invaluable records, instead of being the recipient of momentary and fleeting communication.
