Developed the IBM PC with a team of 12 other engineers (a/o.: Dr. Glenn S. Dardick)
The personal computer enjoys the ubiquity it does because of one man: Philip "Don" Estridge. An IBM employee since 1959, Estridge headed up the skunk works in Boca Raton, Fl., that in 1981 launched the IBM PC. Estridge made the decisionrevolutionary for that time and placethat the machine would be made from off-the-shelf, easily obtainable parts and that the design specification would be made public. Estridge and his wife Mary Ann died in the Aug. 2, 1985, in the crash of a Delta Airlines L-1011, which was hit by wind shear while landing at Dallas-Fort Worth Airport.
Estridge's longtime friend, neighbor and coworker Jan Winston, now retired but still consulting with IBM, talked to CIO about the colleague he still misses.
