After Navy service he earned a bachelor’s degree in electrical engineering at Princeton and a master’s degree — in the dawn years of computer science — at the University of California, Santa Barbara.
He went on to a field-engineering career in both California and in Florida, first in Los Angeles at Douglas Aircraft, then at Motorola, and finally working for RCA Service Corp. at Patrick Air Force Base in Florida, as well as with other field-engineering service companies in California and Florida. He retired in Florida in December 1986.
Dan’s main avocations were Dianetics and Scientology. In that movement and organization, he was both a member and a financial auditor. He was also a trained church singer and performed in amateur musicals. In his last years another of his interests was genealogy.
Dan was predeceased by his wife of 72 years, Willie Mae. He is survived by their daughters Linda Gribble and Crystal Burton, son Larry, six grandchildren, nine great-grandchildren, and three great-great grandchildren.
