Julius Kahn was a United States Congressman who was succeeded by his wife Florence Prag Kahn after his death. He has been described by the American Jerusalem as "among the most influential Jews in San Francisco—as well as national–civic life, from the middle of the 19th century into the 1930s".

Florence Kahn was an American teacher and politician who in 1925 became the first Jewish woman to serve in the United States Congress. She was only the fifth woman to serve in Congress, and the second from California, after fellow San Franciscan Mae Nolan. Like Nolan, she took the seat in the House of Representatives left vacant by the death of her husband, Julius Kahn.
