Why Annie Jump Cannon matters: The people behind the discoveries remind us that science is a human endeavour -- driven by curiosity, persistence, and often the courage to challenge accepted ideas. She was nearly deaf throughout her career after 1893, as a result of scarlet fever. She was a suffragist and a member of the National Women's Party.
