Jackson Whipps Showalter (February 5, 1859 in Minerva, Kentucky â February 5, 1935 in Georgetown, Kentucky) was a four-time U.S. Chess Champion: 1892, 1894, 1895-1896 and 1906âÂÂ1909.
Showalter won U.S. Championship matches against Max Judd (1891/92, +7âÂÂ4=3), Albert Hodges (1894, +7âÂÂ6=4), Samuel Lipschutz (1895, +7âÂÂ4=3), Emil Kemény (1896, +7âÂÂ4=4), and John Finan Barry (1896, +7âÂÂ2=4). He lost championship matches to Samuel Lipschutz (1892, +1âÂÂ7=7), Albert Hodges (1894, +3âÂÂ5=1), Harry Nelson Pillsbury (twice, 1897 (+8âÂÂ10=3) and 1898 (+3âÂÂ7=2), and Frank Marshall (1909, +2âÂÂ7=3).
Other match results: Max Judd (1890, +3âÂÂ7=0), William H.K. Pollock (1891, +3âÂÂ2=3), Emanuel Lasker (1892/93, +2âÂÂ6=2), Jacob Halpern (1893, +5âÂÂ3=1), Adolf Albin (1894, +10âÂÂ7=8), David Janowski (four times: 1898, +2âÂÂ7=4; 1899, +4âÂÂ2=0 and +4âÂÂ2=1; 1916, +2âÂÂ7=2), Boris Kostià(1915, +2âÂÂ7=5), and Norman T. Whitaker (twice: 1916, +6âÂÂ1=0 and 1918, +1âÂÂ4=3).
He also competed in the Anglo-American cable matches against Great Britain from 1896 to 1901, compiling a +4âÂÂ1=1 record.
Showalter was known as "the Kentucky Lion" after his birthplace and his hairstyle, which consisted of a thick mane down the back of his neck, and perhaps also his playing strength. His wife Nellie was one of America's leading female players, who won a match against Emanuel Lasker at knight odds 5âÂÂ2.
A variation of the Queen's Gambit Accepted is named after him (1.d4 d5 2.c4 dxc4 3.Nf3 Nf6 4.Nc3).
The famous "Capablanca Simplifying Maneuver" in the Orthodox Variation of the Queen's Gambit Declined (1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Bg5 Be7 5.e3 Nbd7 6.Nf3 0-0 7.Rc1 c6 8.Bd3 dxc4 9.Bxc4 Nd5) had in fact been used by Showalter in the 1890s, many years before José Raúl Capablanca played it.
Showalter was inducted in the World Chess Hall of Fame on August 7, 2010. His great-granddaughter, Amy Showalter, attended the ceremony and accepted the plaque on behalf of the Showalter family. The content of the induction speech was supplied by Kevin Marchese of Columbus, Ohio, who has recently completed a comprehensive biography on Showalter that is slated to be released by Russell Enterprises, Inc. in the fall of 2026.
