Roosevelt from 1920, when FDR campaigned for vice-president, until she became incapacitated by a stroke in June 1941. She was born in Potsdam, New York, on September 13, 1896, and grew up in Somerville, Massachusetts. After graduating high school in 1917, she attended secretarial school and subsequently, employed at the national headquarters of the Democratic Party where she met Franklin D. Roosevelt. When Roosevelt was stricken with polio in 1921, Missy accompanied him to Warm Springs for treatment.
