Bob Wallace, one of the first dozen Microsoft employees, has died at the age of 53. Wallace is believed to have coined the term "shareware", and wrote the PC-Write shareware program that vast numbers of IBM-compatible PC owners used in the early 1980s. He founded Quicksoft in 1983, and sold the company in 1991. In the famous "first Microsoft" photo in the Seattle Times, he's in the centre of the back row.
