Early years and education
Dorothy McEwen was born on 3 March 1943 in Seattle, Washington, USA. She was the daughter of Marion Strout and Gene McEwen.

In 1980, she was involved in IBM's unsuccessful attempt to license CP/M for the IBM Personal Computer. In 1983, the company's revenue was $44.6 million and CP/M had become the standard operating system on most microcomputers. In 1991, Gary Kildall sold the company to Novell for $120 million.
