From Wikipedia, the free encyclopedia.
Sir Frank Watson Dyson (January 8 1868-May 25 1939) was an English astronomer.
He was Director of the Royal Greenwich Observatory (and the Astronomer Royal) from 1910 to 1933. In 1928, he introduced a new free-pendulum clock in the Observatory. This wireless transmission meant that Greenwich Mean Time was more accurate. He also invented the six pips in 1924.
Dyson was born in Measham, near Ashby-de-la-Zouch in England. He was knighted in 1915. He died while traveling from Australia to England in 1939.
Between 1894-1906, Dyson lived at 6 Vanbrugh Hill, Blackheath, London SE3. The house is now marked by a blue plaque.
