Stephanie Shirley

Dame Stephanie "Steve" Shirley – Pioneer of the Independent Software Industry

Biographical Overview

Founded Freelance Programmers in 1962, creating one of Britain's first independent software houses and proving software could be sold as a standalone product. Shirley employed female programmers working remotely from home with pencil and punch cards, and her company wrote safety-critical assembly code including the Concorde airliner black box flight recorder.

"You can always tell ambitious women by the shape of our heads: they're flat on top for being patted by men, and we have larger feet to stand our ground."

Historical Context & Impact

In short

When Stephanie Shirley started her software company from her dining room table in 1962, her sales letters to prospective corporate clients went almost entirely unanswered. She began signing her letters as "Steve Shirley"—a nickname her father had used—and business inquiries poured in, allowing her to recruit hundreds of women programmers working from home.
