Jacques Laffitte
The Hippodrome de Maisons-Laffitte at 1 avenue de la Pelouse in the northwestern Parisian suburb of Maisons-Laffitte in France was a turf horse racing facility and track for Thoroughbred flat racing. Opened in 1878 by Joseph Oller, inventor of the pari-mutuel machine, it sits on 92 hectares that belonged to the wealthy banker Jacques Laffitte.
