In 2006, when Maria Klawe became the fifth president of Harvey Mudd College, only 10 percent of the school’s computer science majors were women. Within a decade, that…

In 2020, Marian Croak was inducted into the National Inventors Hall of Fame — only the second Black woman ever to receive that honor. With over 200 patents…

Marissa Mayer joined Google as its twentieth employee and first female engineer, shaped the UX of Search, Maps, Gmail, and News, then became CEO of Yahoo. Her data-driven design principles transformed how billions interact with the web.

Mark Dean co-invented the ISA bus architecture that made the IBM PC expandable and open, enabling the entire PC clone industry. He became the first African-American IBM Fellow and led the team that broke the gigahertz barrier.

In the world of operating systems, few people have ever achieved the kind of deep, almost surgical understanding of Windows internals that Mark Russinovich has demonstrated throughout his…

In the early 2000s, the Linux desktop was a fragmented landscape — powerful but inaccessible, beloved by hackers but feared by everyone else. Then a South African entrepreneur…
