"From the earliest days of his career, David Packard set high standards for himself and those around him. His sense of integrity, respect, and compassion for individuals and their capabilities formed the basis for the Hewlett-Packard management approach known as the "HP Way." David believed that "management has a responsibility to its employees, to its customers, and to the community at large," and under his leadership, Hewlett-Packard pioneered many innovative benefits and management concepts, such as flexible working hours, catastrophic medical coverage, and open offices.
"Despite the demands of his business, David found time to participate in many educational, professional, and civic organizations and served as Deputy Secretary of Defense from 1969 to 1972. He was also a member of the President's Council of Advisors on Science and Technology, the Stanford University Board of Trustees, and the Palo Alto School Board."
