Stephanie Shirley

When Dame Vera Stephanie “Steve” Shirley set out to build her own company with only £6 in 1962, she was determined to engineer not just software but opportunity. In an era when most doors were closed to women in technology, she redefined the possibilities for both work and gender, building a thriving firm employing thousands and shaping the modern culture of remote and flexible work. Her team’s projects included the high-stakes programming of Concorde’s black box flight recorder, directly influencing aerospace safety and showing that women could lead at the highest levels of technological innovation[1].

Born Vera Buchthal in Dortmund, Germany, in 1933, Shirley was the daughter of a Jewish judge who lost his position to the Nazi regime. At just age five, she and her older sister escaped Nazi persecution through the Kindertransport in 1939, arriving in Britain as child refugees and separated from their parents. Raised by foster families, she showed early aptitude—and persistence—in mathematics, earning permission to study the subject at the local boys’ school, despite postwar prejudices. She became a British citizen at 18 and changed her name to Stephanie Brook, later Shirley. Sustained by a sharp intellect and resilient spirit, she worked by day and studied by night, taking six years of evening classes to earn an honours degree in mathematics. This dual commitment to learning and hard work would define her subsequent career[2].

In the 1950s, Shirley began her career building computers from scratch and writing machine code at the Post Office Research Station—the same facility responsible for ERNIE, the hardware random number generator used for the UK’s premium bonds lottery. She also contributed at CDL Ltd to one of the earliest British commercial computers, the ICT 1301. In 1962, after years of experiencing sexism and exclusion in the field—including missed promotions and unwanted advances—she founded Freelance Programmers, deliberately to create meaningful work from home for women, especially mothers. Adopting the name “Steve” to counter bias in business communication, she quickly proved effective. Only three out of her first three hundred hires were men, a practice maintained until the Sex Discrimination Act of 1975 required her to open hiring further. The company, which would be renamed Xansa, rapidly grew, employing up to 8,500 staff and creating 70 millionaires among her employees as it approached a £3 billion valuation. Shirley’s hands-on technical leadership extended to major contracts, notably leading the team that programmed Concorde’s flight recorder, contributing to global aviation safety. Through all phases of growth, she worked closely with her husband, physicist Derek Shirley, who provided enduring personal and intellectual partnership since their marriage in 1962[3].

Retiring from business in 1993, Dame Stephanie quickly redirected her energies into philanthropy, supporting causes in IT, autism research, and the arts. She was instrumental in developing software standards that would later be adopted by NATO, as well as pioneering remote and flexible working arrangements that influenced corporate cultures worldwide. Colleagues such as Oxford Professor Sue Black have highlighted her transformative impact: “She didn’t just open doors for women in tech, she built the doors and handed out the keys”—a reference both to Shirley’s organizational innovations and her commitment to empowering others. Shirley herself once reflected, “I created a company for women, but it turned out to be for women with dependants; only three of my first three hundred staff were male until the Sex Discrimination Act in 1975 made that illegal.” Accolades came steadily: Dame Commander of the Order of the British Empire, Companion of Honour, Fellowship in the Royal Academy of Engineering, and multiple honorary doctorates and fellowships from leading institutions. Her influence remains evident in countless globally adopted business practices, improved opportunities for women in STEM, and a philanthropic legacy recognized far beyond the tech world[4].

Dame Stephanie Shirley passed away in 2025 at the age of 91, leaving an enduring record of measurable achievement and lasting change. Her life stands as a testament not only to technical and business ingenuity but to the transformative potential of persistent, value-driven leadership. Her story is preserved in archives, interviews, and in the doors she unlocked for generations of women and underrepresented professionals in technology[1].
