In the Hayes-less universe we might be left to wallow in a morass similar to the a Blu-ray vs. HD-DVD swamp with multiple incompatible wireless standards. In 1990, Hayes formed the Wireless LAN working group and rallied some 130 companies to work together to develop open standards. The result: 802.11, and the cutting of a very firmly attached cord. Hayes continues to be actively involved in Wi-Fi development today.

The 27KB program can run on PCs today, and its simplicity is a big reason why early PCs sold in droves, especially to business customers. But never mind the bean-counters: You probably owe a lot to VisiCalc yourself. After all, if it weren't for Bricklin and Frankston, you might not be getting your paycheck regularly.
26. Grace Murray Hopper
Courtesy of Naval Historical CenterThat's Admiral Hopper, bud. Naval officer "Amazing" Grace Hopper was a computing pioneer who cut her teeth in the calculator era. Later she 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). Hopper was instrumental again in the development of the COBOL and FORTRAN programming languages, and she remained a major figure on the technology scene until her death in 1992. Even our language owes a debt to Hopper: She popularized (and possibly coined) the term "bug" after a moth was found in a computer relay during her years at Harvard.Jeff Hawkins (#27) to Karlheinz Brandenburg and James D.

Courtesy of Ed SchipulPortable computing was shaped in large part by Jeff Hawkins, who invented the acclaimed PalmPilot, and then followed that up by spearheading development of the Treo six years later. Both Palm and Treo became household names, though Palm as a company has suffered numerous setbacks in recent years. Hawkins is now working on a startup called Numenta with his longtime partner Donna Dubinsky, focusing on the subjects of machine learning and neuroscience, which Hawkins has long had a deep interest in.

Courtesy of Unisantis ElectronicsIf anything is positioned to challenge the dominance of Al Shugart's hard drive (see #33 below), it's Flash memory--an invention of Fujio Masuoka. Masuoka developed solid-state storage during his tenure at Toshiba (Masuoka says that the company initially tried to demote him after he came up with the technology). The technology is now seen as a possible way around the fragility of hard drives, as capacity ramps up and prices fall. For smaller gadgets, Flash has become essential...or would you prefer to be saving your digital pictures on floppy disks still?
