Rear Admiral Grace Hopper, pioneering computer scientist and educator, is celebrated in our new hard enamel necklace, part of our Women in Science series.
As one of the first computer programmers, Hopper used binary code to program the Mark I computer. But she had a vision for a better way: She created the first computer language that used words to tell computers what to do.
Hopper also dedicated her life to educating people about how computers work. She always carried "nanosecond wires" with her to use in her lectures. These 11.8” (30cm) wires represented the maximum distance a signal can travel in 1 billionth of a second. This tie bar is a wearable version of her nanosecond wires: The white line on the tie bar is 11.8” long.
