Dean Grafton was born September 21, 1924, in Mt. Pleasant, Ohio. He attended school in this coal mining community through high school. After graduation from high school in May, 1942, Dean began his collegiate studies at Ohio State University. His stud- ies were interrupted in 1943 by WW II when he enlisted in the U.S. Navy and began training at the Great Lakes Naval Station. He served at Great Lakes until 1944, attaining the rank of Seaman First Class. When preparing for deployment, Dean was found to have serious problems with his feet and he was excused from service and honorably discharged. Dean returned to Ohio State University and graduated in 1948 with a Bachelor of Science degree in Geology. He began his career in petroleum geology in the Permian Basin of West Texas in January, 1949. After five years in West Texas, Dean moved to Houston and remained there throughout the remainder of his career. After 36 years of service in the petroleum industry, Dean retired from Occidental Petroleum, having previously worked for Cities Service Oil and Gas. Dean married his wife, Georgia Hosek, in 1965. Georgia was very supportive of Dean’s geologic activities while pursuing her own career as an artist.


Dean was active in several geologic organizations, par- ticularly AIPG, where he served on the National Executive Committee as an Advisory Board Representative in 1981, Vice President in 1982, President-Elect in 1983, and President in 1984. He served as Texas Section President in 1985. He was also active in the Houston Geologic Society where he served in several administrative positions (including President), and AAPG. Dean was a unique individual with a superb intellect who valued his independence.
