While not courageously battling polio, the Great Depression, or the Nazis, Franklin D. Roosevelt was also a notorious womanizer. He married his cousin, Eleanor Roosevelt, then began an affair with her social secretary, Lucy Mercer. But Eleanor's most interesting extramarital escapades included a White House bodyguard and a female reporter.
