Mental Floss just launched a new podcast with iHeartRadio called History Vs., and our first season is all about Theodore Roosevelt. While at Harvard, Roosevelt met his first wife, Alice Lee. Vice President Roosevelt became president in 1901 immediately following the assassination of sitting president William McKinley. Roosevelt’s White House was no place for anyone skittish over animals. The eldest of Roosevelt’s children—and the only one with his first wife, Alice— Alice Roosevelt was 17 when her father took office and quickly became infamous for a series of public indiscretions.
