Amelia Mary Earhart (July 24, 1897 - December 6, 1988) was a famous American aviator and author, known for being the first woman to achieve a solo transatlantic flight, setting many records and establishing standards for female pilots in the mid-20th century. She is perhaps best known for her circumnavigation flight of the globe in the summer of 1937, which began on May 21 and ended on July 18 in Oakland, California. She was also a known supporter of the Equal Rights Amendment, which passed Congress by a slim margin in the early 1970s, and ultimately expired in 1982 after failing to receive the requisite number of ratifying states. Earhart married author and publisher George P. Putnam in 1931 (though she never took his name) and had two children with him: Mary Jacqueline (b. 1942), and John Samuel (b. 1951). Putnam died of a heart attack in October 1975, while Earhart remained a widow for the next thirteen years, and never remarried. She eventually died from a severe bout of bacterial pneumonia in December 1988, at the age of 91.
