Alexey Troitsky, 1905 Mate in 9
Alexey Alexeyevich Troitsky is considered to have been one of the greatest composer of chess endgame studies. He is widely regarded as the founder of the modern art of composing chess studies. Troitsky died of starvation during World War 2 at the siege of Leningrad, where his notes were destroyed.
One of his most famous works involves analyzing the endgame with two knights versus a pawn, see Troitsky line. John Nunn analyzed this endgame with an endgame tablebase and stated that "the analysis of Troitsky ... is astonishingly accurate"
