From writing on paper to giant data warehouses, the story of people who kept our information safe

In 1890, US Census Bureau clerks were spending years writing down every person's details by hand, and the work never ended. Then an inventor showed up with a machine that punched holes in cards and said, "Just read the hole positions and the computer will count for you." That's how the era of handing information over to machines began. Decades later, bank tellers and aerospace managers were saying, "We want to find a customer record or a part in one second," and they started testing new approaches.

In the 1970s, scholars proposed, "Let's organize information into neat tables," and companies took that idea and built enormous systems on top of it. Once the internet era arrived, companies like Facebook and Google hit a new worry — "How do we safely store billions of people's information all at once?" — and every time, someone found an answer with a new tool.
