She worked at army camps where soldiers were dying of yellow fever and then volunteered to go to Havana, Cuba, to participate in experiments to determine the cause of that disease. She was bitten by a mosquito and died 10 days later of yellow fever. She was one of the first nurses to be inducted into the Hall of Fame of the American Nurses Association.
