Erik Thomas Waterhouse Addyman, born in Starbeck, Harrogate, Yorkshire
in 1890, the son of James and Edith Addyman, was another of those larger than life characters that seemed to be part of early
British aviation. His father, a solicitor, was Norwegian Vice-Consul (hence Erik not Eric). He trained as an engineer at Kitson's
College in Leeds. During the First World War he initially worked at the Portsmouth School of Mines researching depth charges
and later he moved to Dumphries, to the Arrol Johnson Engineering Works, during which time he was awarded several patents
associated with improvements to the internal combustion engine.
In July 1920, Erik married Evelyn Mary Fisher,
having three sons, James Cadwallader, Oscar Thomas and Peter Vincent. Later in the 1920s he moved back to Starbeck and used
his engineering background to build at least five motor cars. He also was a keen pot-holer and climber and was a reserve in
the Mallory-Irvine Everest attempt in 1924.
In January, 1930, The Harrogate Aircraft Club was formed with Addyman
as the Hon. Secretary. Their first construction was a Dickson Primary built by and for the use of members and it was in this machine that Addyman suffered a serious accident on February 14th,
1932, breaking both legs and requiring the lower part of his right arm to be amputated.
Despite this handicap,
Addyman was soon to design his own gliders, the Zephyr sailplane in 1933 followed by the Standard Training Glider in 1934.
He also intended to fit an Anzani to an S.T.G. type but although work was begun in 1936, it was not completed.
Waterhouse died in Harrogate, Yorkshire, on 24 January 1963
