Personal Computer Pioneer Among Crash’s Victims With PM-Delta Crash Bjt

August 5, 1985

MIAMI (AP) _ Philip D. ″Don″ Estridge, who guided the development of IBM’s highly successful personal-computer business, was among six IBM employees killed in the crash of a Delta Air Lines jet in Dallas, the company said.

Estridge, 47, of New Canaan, Conn., was heading for Dallas to visit a daughter. His wife, Mary Ann Estridge, also was killed in the crash, as were six other family members of IBM employees and two IBM summer interns, said IBM spokesman John Pope in Boca Raton, Fla.

The employees had been on a business trip to International Business Machines Corp.’s personal-computer complex in Boca Raton when the Lockheed L- 1011 jumbo jet crashed Friday while attempting to land at the Dallas-Fort Worth Airport, killing a total of 133 people.

″Don Estridge was a man of vision whose skill and leadership helped guide IBM’s personal-computer business to success,″ said John F. Akers, president and chief executive of IBM, which is based in Armonk, N.Y.

Estridge, who is survived by four daughters, became one of the best-known figures in the personal-computer business following the success of IBM’s entry into the field four years ago.

Under his leadership, IBM employees developed a personal computer that according to analysts quickly became the industry standard after its introduction in August 1981.

By the time Estridge left the division last March to oversee IBM’s worldwide manufacturing, the personal-computer division employed 10,000 people and generated an estimated $4.5 billion in annual sales.

Estridge, a native of Florida, joined IBM as a junior engineer in 1959 and spent most of his early career working at the Kennedy Space Center on computer systems for the Apollo moon missions.
