Who were the 3 U.S. presidents in the period before the Great stock market crash of 1929 and the beginning of the Great Depression and what political parties did they belong to? wait ....gene...2 things. I think you missed Hoover. Wasnt Hoover president also right before the crash occurred? I am sure of it. Also you did not mention their parties. So I think you meant to say Hoover (Republican), Coolidge (Republican) and Harding (Republican) as the correct answer
