The brothers had some good years and some bad years. Groucho lost a lot of money in 1929, when the stock market collapsed. (Years later, he visited the New York Stock Exchange, and drew so much attention that trading stopped for several minutes. Groucho joked that he came "to get his money's worth" in stopping business.) Chico had a problem with gambling, and lost more money than he won at it. Harpo and his wife could not have children of their own, so they adopted enough to have a large family. (When Adolf Hitler took control of Germany in the 1930s, and stories came back about his mistreatment of Jewish people, Harpo legally changed his name from Adolph to Arthur, even though he was better known as Harpo.)
