Lew Platt, the former HP chief executive officer, has died of a brain aneurism, aged 64.
Platt served as HP CEO from 1992 to 1999. Since 2003, he had been lead director at Boeing.
He was credited with making it easier for women to take more senior positions at HP.
Platt was succeeded as CEO by Carly Fiorina, who was later ousted by the HP board at the beginning of this year.
Platt joined HP in 1966 and worked his way up through the ranks. He was a graduate of Cornell University and the University of Pennsylvania's Wharton School of Business.
Platt resigned his position in 1999 after spinning off HP’s test measurement group into Agilent Technologies.
