Horatio Bolton (02-06-1793 - 15-08-1873) British composer

Gary Kevin Ware did a good job on ChessProblem.net to present Horatio Bolton and Colin Vaughn's discovery,

"from S.S. Blackburne's "Terms and Themes of Chess Problems", that the Reverend Horatio Bolton was a Norfolk clergyman, and a "fine composer of the old school. He used to be regarded as the Father of the Problem Art in England and was a master composer of his day." Horatio Bolton is the subject of the first chapter of Das Indische Problem by Johannes Kohtz and Carl Kockelkorn, "Das indische Problem", and this also happens to be the first problem in that book."

The problem is widely known, but it still deserves your attention and has been reproduced below.
You might also find interesting this page about the K+2S vs K+P study (Horatio Bolton, 1840) which influenced Troitzky: inspired by Bolton's study, he thoroughly analyzed this endgame K+2S vs K+P. and published the analysis in "Chess Studies" (1937).
