"I had a running compiler and nobody would touch it. ... they carefully told me, computers could only do arithmetic; they could not do programs."
~Grace Hopper (9 December 1906 – 1 January 1992)
American admiral and computer scientist, (designed COBOL) Grace Hopper was born #OTD in 1906.
She created the first compiler, the A-0 System, in 1952. She was also one of the first programmers on the Harvard Mark I computer. Hopper popularized the term "debugging" in computing after discovering an actual moth causing a malfunction in the Mark II computer.
