Louis Bernard Zapoleon was born in Grodno, Russia (today: Belarus) as the 5th of 7 children of optician Samuel Movsha Zapoleon (1852-1937) and Pauline Makower (1852-1931). The family of nine came to USA in 1891, and settled in Dayton, Ohio where they rented a house for Samuel's practice. Louis went to elementary school and educated as an economist at Dayton University. He was employed in the US Dept. of Agriculture (Washington, 1909-1916), US Tariff Commission (Washington, 1917-1925) (incl. as expert in a Senate committee, 1921-1922), Stanford University Food Research Institute (Palo Alto California, 1925-1935) (incl. a trip to Denmark in 1925 and two years in Europe 1933-1935), US Security and Exchange Commission (Washington, 1935-1941), and the US War Production Board (1942-1945). He authored books* on agricultural economy, and also left behind him the Louis B. Zapoleon Memorial Scholarship fund which is today administered through the Cincinnati Scholarship Foundation.
Louis was married in 1937 to the equally scholarly Marguerite Wykoff (1907-2003), who had studied economics in London, did graduate work in Switzerland, and attended the New School for Social Research in New York. She worked for the Dept. of Education, Dept. of Labor, as well as the Pentagon. They met at Brookings Library (Washington) in 1935. After World War II they purchased 354 acres of land on Sideling Hill near Berkeley Springs, West Virginia (= Eidolon Nature Reserve#) where they built a cabin and spent weekends and summers. They retired ca. 1955 to Fort Lauderdale, Florida, where he suffered from a stroke in 1960 and died of heart problems in 1969. They had no children.
The career left him with time for chess. He played in the Dayton Chess Club, and was tri-state (Ohio) champion (1909 or before). He was also state champion of Columbia (1910 or before). In 1910 he defeated Frank Marshall in his simul in the Washington Chess and Whist Club. After joining the Capital City Chess and Checkers Club (CCCCC) he won the club tournament there four times (1912, 1915 and two more times). All this qualified him to play in the American National (1913) tournament where he ended last (+1 -10 =2), but drew with Marshall and defeated Charles Jaffe. He held simuls against CCCCC club mates several times, incl. on 1 March 1912 (+9 -2 =1) and in Dec. 1914 (+11 -1). He also played for the club in telegraph matches, e. g. in 1919 when he defeated Manhattan player Leon Rosen, and in Kriegspiel tournaments.
His last appearance on the chess scene was perhaps in 1926 when Emanuel Lasker held a simul in the Mechanics' Institute Chess Club (San Francisco). He was then adjudicator.
