Signature

Claude Hamilton Verity (1 May 1880 – 15 August 1949) was a hardware merchant, engineer and inventor, working mainly in Harrogate and Leeds, England. He was one of the earliest inventors of methods of synchronisation of sound with silent films. For that purpose, and working alone, he invented the Veritiphone, a sound box which could be operated by staff in cinema projection rooms. In the 1920s he demonstrated his invention in various locations in England, and also in New York for the Vitagraph Company of America.

Claude Hamilton Verity came from a Yorkshire family. His grandfather was railway ganger Charles Verity,^{[nb 1][1]} "a man of comparatively little education" who recalled "the days when he went from town to town in search of work, with his tools on his back, [and] the humble meals he was wont to eat under the shelter of the friendly hedge".^[2] He rose to be a wealthy contractor, building bridges and houses, and became mayor of Doncaster.^[2][3][4]

One of Verity's uncles was railway engineer Charles Henry Verity, owner of the Railway Wheel and Wagon Works at Swinton.^{[nb 2][5][6]} Another uncle was ironmonger Joshua Marland "Fred" Verity,^{[nb 3][7]} who started the family hardware manufacturing and wholesale business Fred Verity & Son at 174-178 Lower Briggate and 60-68 Call Lane. This address was on part of the site where Louis Le Prince made his first moving picture.^[8] C.H. Verity's father was Leeds ironmonger and hardware shop manager Edwin Verity, who was born in Stanley, West Riding of Yorkshire.^{[nb 4][9]} Edwin and his elder brother Fred, known as Verity Brothers, were brought up by their uncle James Rogers, a shoemaker and farmer, because their mother died in the year when Fred was born and Edwin was two years old.^{[nb 5][10]} Edwin and Fred ran the hardware business together,^[8][11] and Edwin served on the Leeds Board of Guardians.^[12] C.H. Verity's mother was Ann "Annie" née Thornton. Edwin and Ann Verity married on 21 December 1871 in St Peter's Parish Church, Leeds.^{[nb 6][8]} In 1897, when Fred died, Edwin moved or expanded the business to new premises at 189 Briggate,^[13] and continued in the business until his sudden death in 1909.^[12]

Verity, the youngest of four siblings, was born in Leeds in 1880,^[8] with the birth name "Claud".^{[nb 7]} He lived in Roundhay as a child. In 1881 the family was living at 53 Sholebrook Avenue, Potternewton.^[14] By 1891 the family had moved to number 34 in the same street, his brother, Charles Frederick,^{[nb 8]} was apprenticed as an ironmonger, and Claude (now spelled with an "e") was a scholar at board school.^[15]

On 7 September 1917 in Kensington, Verity married Riva Alice Mary Seller, who was sixteen years his junior.^{[nb 9][16][17]} They had three children: Diane "Diana" Faith Verity,^{[nb 10][16]} Sheila Hope Verity,^{[nb 11][16]} and Stuart Hamilton Verity.^{[nb 12][18]} By April 1921, Verity and his family were living at 9 East Park Road, Harrogate.^[16] The 1939 Register finds Verity living at 19 Connaught Road, Harpenden, Hertfordshire, describing himself as a retired hardware merchant.^[19] At the end of his life, Verity was living in Torquay, Devon,^[20] and he played bowls at the Lynton and Lynmouth Bowling Club.^[21] Verity died in Devon on 15 August 1949. He left £1,482 7s 8d. (equivalent to £66,153.16 in 2023).^[20][22][23]

  Verity lived in Harrogate in the 1920s.

During his early adult life, Verity's career was apparently unsettled. In 1901, the census shows a Leeds-born Claude Verity, aged 20, as a student of an agricultural college, living in a bedsit in Moot Villa, Moot Lane, Downton, Wiltshire.^[24] His father Edwin died suddenly of heart failure in 1909,^[12] and he and his brother inherited the family business, but by 1910 he was describing himself as an "engineering draughtsman" at Seacombe, Liverpool. The 1911 census finds Verity as a boarder in Cliff Road, Falmouth, Cornwall, living on his own means.^[25] In 1912 he was in Scarborough, the birthplace of his future wife.^[8]

It so happened that Verity grew up in Roundhay where Louis le Prince, the inventor of an early motion-picture camera, had lived. It also happened that Verity's workshop in Briggate was close to Leeds Bridge where le Prince had shot his film of traffic in the late 1880s. However le Prince disappeared in 1890 when Verity was ten years old, so there was no direct engineering connection between them.^[8] Nevertheless, Verity was one of the first to work on the synchronisation of sound with film.^[26]

[Verity's earliest experimentation was built on] the earlier experiments of Dickson's 1893 Kinetoscope, Gaumont's Paris demonstration of 1900, and Oskar Messter's Kosmograph demonstrated in Berlin in 1903. Important though those efforts were, it was the general opinion that synchronisation was less than perfect, and it was this problem that Verity attempted to overcome in his laboratory [in Harrogate].^{[27]: 1187, 1188}

He worked on his invention and improvement of synchronous sound in the cinema in Harrogate and Leeds from at least 1915,^[28][29] while supporting himself as a hardware merchant at 168–169 Briggate, Leeds, although he temporarily converted part of the hardware shop to a workshop.^[8] The main laboratory for his inventions between 1915 and 1920 was at the back of his home in Harrogate where, according to historian Malcolm Neesam: "it was reached by an external folding staircase which guaranteed complete privacy". In obtaining the required sound recordings, Verity was assisted by Julian Clifford and his musicians.^{[27]: 1187, 1188}

Verity worked for five years in secrecy before patenting his work. It was in effect a type of dubbing operation, in which he used the gramophone record system to record voice-actors synchronising their words with the lip-movements of silent-film actors. Much of the patented material concerned the maintenance of the synchronisation between gramophone and film playback.^[30][31] In April 1922, the Yorkshire Evening News said that Verity was looking for financial backers, but "did not intend to work on the lines of a monopoly in regard to his invention". The newspaper described the effort and expense of Verity's inventive efforts, without the support of a large organisation:^[8]

For over three years [Verity] has been perfecting his idea [of synchronising sound with film], and so far it has entailed a cost of £7,000 (equivalent to £482,815.16 in 2023) but now to quote his own words: With my system of synchronisation I can guarantee to keep this relation of sound and lip movement under synchronous control to within one-twenty-fourth of a second for any length of time ... The solving of the problem of synchronisation was proved and admitted by the critics at Mr. Verity's first trade show in Harrogate [where the gramophone proved to be inaudible to the back of the crowd, so needed improvement].^[8][23]

In 1921 and 1922, Verity was showing his synchronisation of sound and movement in film, first in Harrogate as described above, then in Bradford, London and Leeds, where "[his] system worked well and was popular".^[8][33] In April 1922, The Yorkshire Evening Post published this description of his demonstration in Leeds:^[34]

Mr C.H. Verity, the inventor of an apparatus which has made the synchronisation of film and gramophone a practical proposition, is the head of a Leeds firm of hardware manufacturers and merchants. He is presenting his talking and singing pictures at the Albert Hall, Leeds, this week. Entertainments will be given each evening, and on three afternoons. The first programme consists of the first film productions under the Verity system of synchronisation. Mr Verity claims that the cost of these productions will be no greater than that of making silent films, because it is cheaper to help out scenes and actions by words than by the multiplication of dumb show. There are interesting possibilities in the production of talking pictures in these days when the demand is all for novelty and originality in entertainment. Four performances recently given in Harrogate attracted over 5,600 people. Although the film projection seemed at times to be a little faulty at this afternoon's entertainment, Mr Verity demonstrated that his system ensures co-timing of the gramophone and the motions of the film artists' lips and their gestures ... Films were purposely broken this afternoon to demonstrate to cinema exhibitors to show that when projection began again, synchronisation had not been interfered with in any way by the most common of camera mishaps.^[34]

By 1922, Verity was calling his invention the Veritiphone system,^[35][36] and by September of that year, he had improved its sound amplification. The Civil & Military Gazette of Lahore published a description of Verity's demonstration in the Waldorf Hotel, London, naming the apparatus as the Veritiphone. It said:^[37]

The new instrument is composed of an ordinary quite cheap sound-box, with a tone-arm, attached to the end of which an amplifying chamber is fitted. In this chamber is placed an electric element, and, by means of suitably-arranged holes in the sound-box and tone-arm, induced draught passes through, so that the apparatus is working under similar conditions to the human throat. Certainly, the result is excellent, and while one still cannot feel that the sounds are absolutely divorced from the mechanism producing them, the clearness in diction of the human voice was quite remarkable ... By means of amplifying instruments the volume of sound emitted can be graduated according to the size of the room.^[37]

In 1922, Jackson Wrigley wrote that the "invention of a synchroniser by Mr Claude H. Verity, a Harrogate engineer, enables the operator, by simply sliding a knob, quite independently of observing the screen, to work synchronisation to the 1–24th of a second".^[38] On 9 November 1923 Verity embarked for New York City on the RMS Aquitania, to be met on Ellis Island by J. Stuart Blackton, the vice president of the Vitagraph Company of America. In New York he showed his developments in "synchronisation of music and talking pictures".^[8][39][33] This led to Verity being mentioned in the New York press.^[40]

In June 1923, Kinematograph Weekly published a letter from Verity, who spelled his name "Claud" on this occasion. He defined the Veritiphone as the "Verity system of synchronised pictures". He said that he used two machines, the projector and the Veritiphone. This equipment could now be used in the projection room, instead of its previous position behind the projection screen, so that projection-room staff could "control synchronised production from the standard projectors at present fitted in any kinema where the synchroniser is installed".^[41]

In the New York Times on 20 January 1924, Verity had his say about the "technical difficulty of the sound film", "the prospects for the sound film" and Verity's improvements, and "the need for the sound film to reinvigorate the interest of audiences". He believed that the contemporary need to pad out silent film showings with music and additional acts, and the fact that small venues could not provide such additions, meant that silent film needed to provide more entertainment by itself. He wanted governments to support inventors and to invest in the future of sound and film.^[33]

Verity patented numerous inventions, including: "apparatus for the inhalation of medicated vapours", "low-temperature carbonisation". "clouderising coal dust", "electric radiators". "revolving doors", and "improvements to stoves".^[8][42] However, today it is his synchronisation of sound with moving pictures for which he is remembered.^[8]
