Harvard "computer" Annie Jump Cannon – one of the remarkable women whose work revolutionized our understanding of the universe long before they could vote – was born on this day in 1863. Deaf, meticulous, she catalogued more than 20,000 variable stars https://t.co/SeETRIfLfr pic.twitter.com/x2LEvYP5TH

This is really neat -- and well deserved.

Annie Jump Cannon classified 350,000 stars during her lifetime. She was so well known in the astronomy field that she became the 1st woman to receive a an honorary doctorate of science from @UniofOxford in 1925 https://t.co/VL4GUjd8Af
