Count Paul Oscar d'Esterhazy (1831-1912) was a Hungarian immigrant, who helped other Hungarians settle in Saskatchewan, Canada. Although he claimed to be a descendent of the artistocratic Esterhazy family from Hungary, there remains little proof of this connection, as well as little information about his life in general.
Ferdinand Walsin Esterhazy (1847-1923) was a descendant of the aristocratic Esterhazy family and an officer in the French army and spy for a German attache in the late 1890s. When one of Esterhazy's note divulging French intelligence to the Germans was discovered, Alfred Dreyfus (1859-1935), a Jewish officer in the French army, was falsely deemed responsible and convicted. This account is known as the Dreyfus Affair.
