In 1913, a 7-year-old girl dismantled every alarm clock in her house to see how they worked. When her mother found out, she limited the girl’s exploration to just one clock – a fair compromise. That little girl was Grace Brewster Murray – also known as Rear Admiral Grace Hopper – who became one of the first programmers of the Harvard Mark I computer in 1944 and continued on to have a 42-year long career developing computer programming for the Navy. Today, 56% of women in STEM careers leave tech within 10 years, more than twice the dropout rate of men.
