History
The fact that two knights can sometimes win against one or more pawns was known at least as early as 1780, when Chapsis did a partial analysis of three positions with the pawn on f4 or h4 (Troitzky 2006:200). In 1851 Horwitz and Kling published three positions where the knights win against one pawn and two positions where they win against two pawns (Horwitz & Kling 1986:64–68). The analysis by Chapsis was revised by Guretsky-Cornitz and others, and included by Johann Berger in Theory and Practice of the Endgame, first published in 1891. However, the analysis by Guretsky-Cornitz was incorrect and the original analysis by Chapsis was in principle correct (Troitzky 2006:200). Troitsky started studying the endgame in the early 20th century and published his extensive analysis in 1937 (Mednis 1996:43). Modern computer analysis found it to be very accurate (Nunn 1995:265).
Master games with this ending are rare – Troitzky knew of only six when he published his analysis in 1937. In the first four (from c. 1890 to 1913), the weaker side brought about the ending to obtain a draw from an opponent who did not know how to win. The first master game with a win was in 1931 when Adolf Seitz beat Eugene Znosko-Borovsky (Troitzky 2006:197–99).

Famous quotes containing the word history:
“When the coherence of the parts of a stone, or even that composition of parts which renders it extended; when these familiar objects, I say, are so inexplicable, and contain circumstances so repugnant and contradictory; with what assurance can we decide concerning the origin of worlds, or trace their history from eternity to eternity?”
—David Hume (1711–1776)
“the future is simply nothing at all. Nothing has happened to the present by becoming past except that fresh slices of existence have been added to the total history of the world. The past is thus as real as the present.”
—Charlie Dunbar Broad (1887–1971)
“It takes a great deal of history to produce a little literature.”
—Henry James (1843–1916)
