    SUBJECT AREA: Recording
    [br]
    b. 18 February 1867 Wilmington, Delaware, USA
    d. 14 November 1945 Moorestown, New Jersey, USA
    [br]
    American industrialist, founder and owner of the Victor Talking Machine Company; developer of many basic constructions in mechanical sound recording and the reproduction and manufacture of gramophone records.
    [br]
    He graduated from the Dover Academy (Delaware) in 1882 and was apprenticed in a machine-repair firm in Philadelphia and studied in evening classes at the Spring Garden Institute. In 1888 he took employment in a small Philadelphia machine shop owned by Andrew Scull, specializing in repair and bookbinding machinery. After travels in the western part of the US, in 1891 he became a partner in Scull \& Johnson, Manufacturing Machinists, and established a further company, the New Jersey Wire Stitching Machine Company. He bought out Andrew Scull's interest in October 1894 (the last instalment being paid in 1897) and became an independent general machinist. In 1896 he had perfected a spring motor for the Berliner flat-disc gramophone, and he started experimenting with a more direct method of recording in a spiral groove: that of cutting in wax. Co-operation with Berliner eventually led to the incorporation of the Victor Talking Machine Company in 1901. The innumerable court cases stemming from the fact that so many patents for various elements in sound recording and reproduction were in very many hands were brought to an end in 1903 when Johnson was material in establishing cross-licencing agreements between Victor, Columbia Graphophone and Edison to create what is known as a patent pool. Early on, Johnson had a thorough experience in all matters concerning the development and manufacture of both gramophones and records. He made and patented many major contributions in all these fields, and his approach was very business-like in that the contribution to cost of each part or process was always a decisive factor in his designs. This attitude was material in his consulting work for the sister company, the Gramophone Company, in London before it set up its own factories in 1910. He had quickly learned the advantages of advertising and of providing customers with durable equipment and records. This motivation was so strong that Johnson set up a research programme for determining the cause of wear in records. It turned out to depend on groove profile, and from 1911 one particular profile was adhered to and processes for transforming the grooves of valuable earlier records were developed. Without precise measuring instruments, he used the durability as the determining factor. Johnson withdrew more and more to the role of manager, and the Victor Talking Machine Company gained such a position in the market that the US anti-trust legislation was used against it. However, a generation change in the Board of Directors and certain erroneous decisions as to product line started a decline, and in February 1926 Johnson withdrew on extended sick leave: these changes led to the eventual sale of Victor. However, Victor survived due to the advent of radio and the electrification of replay equipment and became a part of Radio Corporation of America. In retirement Johnson took up various activities in the arts and sciences and financially supported several projects; his private yacht was used in 1933 in work with the Smithsonian Institution on a deep-sea hydrographie and fauna-collecting expedition near Puerto Rico.

    Bibliography
    Johnson's patents were many, and some were fundamental to the development of the gramophone, such as: US patent no. 650,843 (in particular a recording lathe); US patent nos. 655,556, 655,556 and 679,896 (soundboxes); US patent no. 681,918 (making the original conductive for electroplating); US patent no. 739,318 (shellac record with paper label).

  • 4 Berliner, Emile

    SUBJECT AREA: Recording
    [br]
    b. 20 May 1851 Hannover, Germany
    d. 3 August 1929 Montreal, Canada
    [br]
    German (naturalized American) inventor, developer of the disc record and lateral mechanical replay.
    [br]
    After arriving in the USA in 1870 and becoming an American citizen, Berliner worked as a dry-goods clerk in Washington, DC, and for a period studied electricity at Cooper Union for the Advancement of Science and Art, New York. He invented an improved microphone and set up his own experimental laboratory in Washington, DC. He developed a microphone for telephone use and sold the rights to the Bell Telephone Company. Subsequently he was put in charge of their laboratory, remaining in that position for eight years. In 1881 Berliner, with his brothers Joseph and Jacob, founded the J.Berliner Telephonfabrik in Hanover, the first factory in Europe specializing in telephone equipment.
    Inspired by the development work performed by T.A. Edison and in the Volta Laboratory (see C.S. Tainter), he analysed the existing processes for recording and reproducing sound and in 1887 developed a process for transferring lateral undulations scratched in soot into an etched groove that would make a needle and diaphragm vibrate. Using what may be regarded as a combination of the Phonautograph of Léon Scott de Martinville and the photo-engraving suggested by Charles Cros, in May 1887 he thus demonstrated the practicability of the laterally recorded groove. He termed the apparatus "Gramophone". In November 1887 he applied the principle to a glass disc and obtained an inwardly spiralling, modulated groove in copper and zinc. In March 1888 he took the radical step of scratching the lateral vibrations directly onto a rotating zinc disc, the surface of which was protected, and the subsequent etching created the groove. Using well-known principles of printing-plate manufacture, he developed processes for duplication by making a negative mould from which positive copies could be pressed in a thermoplastic compound. Toy gramophones were manufactured in Germany from 1889 and from 1892–3 Berliner manufactured both records and gramophones in the USA. The gramophones were hand-cranked at first, but from 1896 were based on a new design by E.R. Johnson. In 1897–8 Berliner spread his activities to England and Germany, setting up a European pressing plant in the telephone factory in Hanover, and in 1899 a Canadian company was formed. Various court cases over patents removed Berliner from direct running of the reconstructed companies, but he retained a major economic interest in E.R. Johnson's Victor Talking Machine Company. In later years Berliner became interested in aeronautics, in particular the autogiro principle. Applied acoustics was a continued interest, and a tile for controlling the acoustics of large halls was successfully developed in the 1920s.

    [br]
    b. 1 March 1880 Kiev, Ukraine
    d. 25 January 1963 Willesden, London, England
    [br]
    Russian engineer and friend of Vladimir Zworykin; Director of Research at EMI, responsible for creating the team that successfully developed the world's first all-electronic television system.
    [br]
    After his initial engineering education at Kiev Polytechnic, Shoenberg went to London to undertake further studies at the Royal College of Science. In 1905 he returned to Russia and rose to become Chief Engineer of the Russian Wireless Telegraphy Company. He then returned to England, where he was a consultant in charge of the Patent Department and then joint General Manager of the Marconi Wireless Telegraphy Company (see Marconi). In 1929 he joined the Columbia Graphophone Company, but two years later this amalgamated with the Gramophone Company, by then known as His Master's voice (HMV), to form EMI (Electric and Musical Industries), a company in which the Radio Corporation of America (RCA) had a significant shareholding. Appointed Director of the new company's Research Laboratories in 1931, Shoenberg gathered together a team of highly skilled engineers, including Blumlein, Browne, Willans, McGee, Lubszynski, Broadway and White, with the objective of producing an all-electronic television system suitable for public broadcasting. A 150-line system had already been demonstrated using film as the source material; a photoemissive camera tube similar to Zworykin's iconoscope soon followed. With alternate demonstrations of the EMI system and the mechanical system of Baird arranged with the object of selecting a broadcast system for the UK, Shoenberg took the bold decision to aim for a 405-line "high-definition" standard, using interlaced scanning based on an RCA patent and further developed by Blumlein. This was so successful that it was formally adopted as the British standard in 1935 and regular broadcasts, the first in the world, began in 1937. It is a tribute to Shoenberg's vision and the skills of his team that this standard was to remain in use, apart from the war years, until finally superseded in 1985.

    [br]
    b. 9 December 1901 Forest Hill, London, England
    d. 9 February 1981 Brighton, Ontario, Canada
    [br]
    English/Canadian electronics engineer, developer of electromechanical recording and reproductions systems, amplifiers and loudspeakers.
    [br]
    He received his education at Dulwich College and in 1922 graduated with a BSc from University College, London. He had an early interest in the application of valve amplifiers, and after graduating he was employed by J.E.Hough, Edison Bell Works, to develop a line of radio-receiving equipment. However, he became interested in the mechanical (and later electrical) side of recording and from 1925 developed principles and equipment. In particular he developed capacitor microphones, not only for in-house work but also commercially, until the mid-1930s. The Edison Bell company did not survive the Depression and closed in 1933. Voigt founded his own company, Voigt Patents Ltd, concentrating on loudspeakers for cinemas and developing horn loudspeakers for domestic use. During the Second World War he continued to develop loudspeaker units and gramophone pick-ups, and in 1950 he emigrated to Toronto, Canada, but his company closed. Voigt taught electronics, and from 1960 to 1969 he was employed by the Radio Regulations Laboratory in Ottawa. After retirement he worked with theoretical cosmology and fundamental interactions.

    Most of Voigt's patents are concerned with improvements in the magnetic circuit in dynamic loudspeakers and centring devices for diaphragms. However, UK patent nos. 278,098, 404,037 and 447,749 may be regarded as particularly relevant. In 1940 Voigt contributed a remarkable paper on the principles of equalization in mechanical recording: "Getting the best from records, part 1—the recording characteristic", Wireless World (February): 141–4.
