Arithmetic Language version 0 was created by legendary computer pioneer Grace Hopper in the early 1950s. It was the first compiler ever made for an electronic computer, and was written for the the UNIVAC I, which Hopper also had a hand in developing. She began developing A-0 in 1951, and new versions led to the A-2 compiler being released to customers in 1953. A-0 later evolved into MATH-MATIC and FLOW-MATIC, but were essentially newer versions of the original. The use of compilers is now synonymous with software development, and an endless variety grew out of Hopper’s original ideas.
