He served as U.S. Deputy Secretary of Defense from 1969 to 1971 during the Nixon administration.

The Hewlett-Packard Company, commonly shortened to Hewlett-Packard or HP, was an American multinational information technology company. It was founded by Bill Hewlett and David Packard in 1939 in a one-car garage in Palo Alto, California, where the company would remain headquartered for the remainder of its lifetime. This HP Garage is now a designated landmark, with a plaque calling it the "Birthplace of 'Silicon Valley'". HP developed and provided a wide variety of hardware components, as well as software and related services, to consumers, small and medium-sized businesses (SMBs), and fairly large companies, including customers in government sectors, until the company officially split into Hewlett Packard Enterprise and HP Inc. in 2015.
