Naval officer Amazing Grace Hopper worked on the team that developed the UNIVAC, the world's first commercial computer, and wrote the compiler software for it (the first such software ever developed). She popularized (and possibly coined) the term bug after a moth was found in a computer relay during her years at Harvard.

Fujio Masuoka - If anything is positioned to challenge the dominance of Al Shugart's hard drive (see slide no.8), it's Flash memory—invented by Fujio Masuoka. Masuoka during his tenure at Toshiba. (Masuoka says that the company initially tried to demote him after he came up with the technology).

Bill Joy was chief scientist for Sun Microsystems for over 20 years, where he oversaw the development of Java. His greatest achievement is probably an academic project he worked on at Berkeley: The development of Berkeley Software Distribution (BSD), a major flavor of Unix; even Mac OS X uses BSD as its basis.

This unassuming twosome got their start in 1994 while still at Stanford, with a truly humble idea: Populate a directory with cool places that they had found on the then-infant World Wide Web. Yahoo was born on a lark but Jerry Yang (left) and David Filo helped it become one of the Web's top destinations.

Before Google -- before the Web even -- people had to find a way to locate files and programs hiding out on FTP servers around the world. The answer: Archie (a derivative of archive), a 1990 application devised by McGill University student Alan Emtage, who was assisted by Bill Heelan and Mike Parker.

Political insider Arianna Huffington has had a major influence on technology, but one that has been felt only recently. In 2005 she launched a little online project called The Huffington Post, which rapidly grew into one of the Web's most powerful political voices. More than anything, the HuffPo has proven the power of the blog.

When Herbie Hancock released his single, Rockit in 1983, everyone was struck by its unique sound. Though Hancock was by no means the first person to make heavy use of computer-based musical equipment, few musicians relied so heavily on such gear. Rockit, with its innovative music video, is now considered a turning point in the electronic music-making scene.
