Eleanor Elkins Widener

Eleanor Elkins Widener (née Eleanore Elkins, later known as Eleanor Elkins Widener Rice or Mrs. Alexander Hamilton Rice; c. 1862–1937) was an American heiress, socialite, philanthropist, and adventuress best remembered for her donation to Harvard University of the Widener Library‍—‌a memorial to her elder son Harry Elkins Widener, who (along with her first husband, George Dunton Widener) perished in the sinking of the RMS Titanic.

Widener later married Harvard professor Alexander Hamilton Rice Jr., a surgeon and explorer, then accompanied him on a number of expeditions, including one on which she "went further up the Amazon than any white woman had penetrated" and, purportedly, he was attacked by cannibals.
