During these years Henry had served as: director of Apple Computers; member of the corporation, MIT (1968 to 1973); trustee of California Institute of Technology (1968 to 1974); member of the U.S. Air Force Scientific Advisory Board (1959); and senior member of the Institute of Electrical and Electronics Engineers. He won the William Lowell Putnam Intercollegiate Mathematics Competition Award in 1939.
He was honored by the Outstanding Achievement Award in Business Management by the University of Southern California in 1972 and by establishment of the Singleton Research Fellowship at the City of Hope Pilot Medical Center in 1970.
His citation for membership in the National Academy of Engineering in 1979 reads, “For his contributions to lightweight inertial navigation systems and his leadership in the creation of a major technological corporation.”
After his retirement, Henry remained eager for new ventures. He bought extensive ranch lands in California and New Mexico and built herds of cattle. He loved these lands and took pride in managing them well. He studied Native American cultures and Western folklore. He played tournament chess, collected fine wines, and loved to hike and camp in the wilderness areas of California. Most recently, he devoted much time to computers, programming algorithms and creating a fine computer game of backgammon for, of course, Macintosh fans.
He is survived by his wife of fifty-seven years, Caroline, five children, and four grandchildren. A book about his love for the ranch San Cristobal in New Mexico and his efforts with local authorities and educational institutions to preserve its history and “petro-treasures” was written by a daughter. When it was my honor to speak at a service after his death, I spoke from knowledge and close friendship of this great engineer for over sixty-four years as I concluded, “Heaven has just gone digital.”
