From the moment I first understood the meaning of my mum’s , Joan Holt, school motto “Be strong and very courageous” I realised it wasn’t just a phrase she carried; it was a quiet force that shaped her life. Long before women in STEM were recognised or encouraged in the way they are today, she worked in a world of theoretical physics, numerical analysis, and early computing with a determination that still leaves me in awe. Hers was not the loud, celebrated courage of someone who set out to break barriers, but the steady, purposeful courage of someone who simply refused to accept that those barriers applied to her. With it being International Women’s Day last week we celebrated the women who paved the way and that reminds that one of those pioneers was my mum.
Her career reads like a living history of British computing. Her first days were working on IBM mainframes and analysing data, when computers filled whole rooms and printouts were the size of phone books to programming the Ferranti Mk1. She drafted manuals for the Elliott 503 and 4100, and solved problems with nothing but symbolic assembly code. She lived through the evolution of technology as few people did. She worked in rooms where magnetic tapes towered over her, where data meant punched cards and where a single mistake meant repunching a deck. She navigated machines that shook themselves off desks, deciphered the results of calculations that once took over 8 months, and wrote documentation that bridged engineers and the future operators. She was often the only woman in the room, one of only a handful among thousands of men at just nineteen. She simply worked hard proving herself indispensable through intelligence, persistence, and grace.
Today, on Mother’s Day, I think not only of the extraordinary work she did, but of the extraordinary woman she was. A role model who taught me that courage can be quiet, curiosity can be powerful, and that you can shape the world even if you never stand in the spotlight. While the world now celebrates women in STEM more visibly than ever, she lived those values when the path was far tougher and the recognition far thinner. Her achievements may sit in old manuals, early programs, and memories of rooms filled with tapes and valves, but her legacy is alive in me. I am proud beyond words to have been her daughter, and prouder still to share her personal story to help inspire future generations.
