He attended Officer Candidate School and served in the U.S. Navy as a lieutenant commander. He was supply officer on a tanker for a year in the Mediterranean, later remaining active in the Naval Reserves until 1991.
After earning a master's degree in mechanical engineering from MIT in 1959, Mr. Blume was drawn to California, where he found work at Fairchild Semiconductor, seedbed for the semiconductor industry. He would design microchips at companies, including Intel Corp, for the rest of his career.
He led the team developing the 8748 and 8048 microcontrollers, which were among Intel's "hottest products" in the late 1970s. In 1970 he earned a master's degree in electrical engineering from Stanford University.
Always an athlete, whether skiing, playing football, tennis or rugby, Mr. Blume went on to become a tennis official with the U.S. Tennis Association, refereeing matches on both coasts, the family said. For 40 years, he rarely missed his Saturday tennis doubles game at Alpine Hills Tennis Club. In addition, in high school, he won the state chess championship and, as an adult, became a life master in bridge.
Mr. Blume is survived by his second wife, Mary Burt; daughters Ann Blume and Frances Richards; and two grandsons.
Donations in his memory may be made to the Infusion Center, Stanford Cancer Center, 875 Blake Wilbur Drive, Palo Alto.
