Captain William Davies Evans (27 January 1790 â 3 August 1872) was a seafarer and inventor best known today for the Evans Gambit, a chess opening.
Evans was born at St Dogwells, Pembrokeshire, Wales. He almost certainly went to Haverfordwest Grammar School, the only school in Pembrokeshire at that time. About the beginning of the century the family moved to Castle Pill, an inlet on the north side of Milford Haven, just east of Milford town.
Evans served at sea in the navy from 1804, when he was 14, until the Napoleonic Wars ended in 1815.
He was then transferred to the postal department. By 1819, he had reached the title of Captain of the sailing packet.
Evans invented tri-coloured lighting on naval vessels to prevent collisions at night. For this invention, the British government awarded him ã1500 and a gold chronometer, while the Tsar of Russia gave him ã200.
By 1818, he had learned the moves of chess.
Around 1825âÂÂ1826, on shore leave in London, Evans played Alexander McDonnell, beating the latter with what is now regarded in chess circles as the first Evans Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4). According to GM Andrew Soltis, Evans was "the first player to be widely honored for an opening we know he played". According to GM Daniel Naroditsky, Evans was also the first player to play the Danish Gambit.
He is buried at the Belgian port of Ostend.
