Horatio St George Anson (1 August 1903 – 30 June 1925)[1] was a British electrical engineer who in collaboration with Stephen Oswald Pearson discovered the Pearson–Anson effect, inventing the neon lamp relaxation oscillator.
He was the son of Admiral Charles Eustace Anson, CB, MVO, Superintendent of the Royal Navy’s Chatham Dockyard (son of Frederick Anson, Canon of Windsor and Caroline Maria, dau.
of George Venables-Vernon, 5th Baron Vernon) and Maria Evelyn, daughter of Horatio S. J. Ross.
[2] As a youth in the Royal Naval College, he developed an interest in research into radio.
There he discovered that the negative resistance of neon lamps could be exploited to create an electronic oscillator.
