Betty Snyder
Betty Snyder — born Frances Elizabeth Snyder (7 March 1917 – 8 December 2001), later Holberton — was an American mathematician, one of the six original ENIAC programmers, and arguably the one who stayed closest to the cutting edge for longest: she invented the breakpoint, helped write COBOL, and spent decades shaping computing standards.
Life
Snyder studied journalism at the University of Pennsylvania — on her first day, a professor told her journalism was no career for a woman and she would do better wasting her time learning something else; she switched to mathematics. She was working as a human computer for the Army when the call went out for six women to program a machine that didn't yet have a name anyone knew: ENIAC.
ENIAC and after
On ENIAC she was known for keeping track of the machine's thousands of interdependent settings — the discipline that would make her indispensable on later machines. When the war ended she joined Mauchly and Eckert's company, becoming a lead programmer on UNIVAC I under Grace Hopper's group — where she designed the C-10 instruction set and wrote the first sort-merge generator, the ancestor of every sorting utility since.
Her most famous single contribution is the breakpoint: at her urging, UNIVAC was built with the ability to halt on a chosen instruction so a programmer could inspect the machine's state — the debugging mechanism every developer still uses. She was a key force in the development of COBOL (1959) and spent her career pushing for machine-independent languages and national computing standards at the National Bureau of Standards.
Legacy
- IEEE Computer Pioneer Award (1997) — the citation credits the breakpoint and her sort-merge work.
- Augusta Ada Lovelace Award (1997) from the Association for Women in Computing — fittingly named for Ada Lovelace.
- Inducted into the Women in Technology International Hall of Fame (1997) with the other five.
- Died in 2001 — the only one of the six whose later career rivaled her ENIAC fame.
