Evans, William Davies
William Davies Evans (1790-1872) was a captain in the mercantile marine and amateur chessplayer. He went to sea in 1804 at the age of 14, and later became a steamer ship captain in 1819. He discovered the Evans Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4) in 1824 while at sea. He first played it against Alexander McDonnell in 1826 and won. In 1845 Evans took part in the first chess game played by telegraph. He may have also founded the first chess club in Ireland. He was active in London chess events and Howard Staunton chose Evans to be his second at chess matches. Later, Harrwitz chose Evans to be his second. In 1871 he invented the system of white, green, and red lights signal lights at sea to prevent collisions. He died in 1872 and was buried in Ostend. His age is wrong on his grave.
