MICROBIOLOGIST & A THEATER OWNER

HATTIE ELIZABETH ALEXANDER Pediatrician and Microbiologist developed the first effective remedies for Haemophilus influenzae, reducing the mortality rate from nearly 100 percent to less than 25 percent. Alexander was also among the first scientists to identify and study antibiotic resistance, which she correctly concluded was caused by random genetic mutations in DNA.  In 1964, she became the first woman elected president of the American Pediatric Society.

LAURA KEENE was the first woman to run a theater.  Originally a success on the English stage, Keene settled in New York City in 1855 and became the first woman to manage her own theatre and theatrical company.  Her production of "Our American Cousin" was playing at Ford's Theatre the night Lincoln was assassinated.  Keene's dress cuff, stained with what is purportedly the slain president's blood—she cradled his head after he was shot—is in the Smithsonian Museum.
