Edward Zagst (1920-1983).


Edward Zagst was born in. Shreveport, Louisiana on April 19, 1920. At the age of 14, his family moved to Houston where he graduated from St. Thomas High School. He attended Rice Institute and graduated in 1943 with a B.S. degree in electrical engineering. He and Helen Halverton were married in 1943. He spent part of 1943 and all of 1944 with Naval Research in Washington, D.C.

In February 1945 he started his oil exploration career on a Seismic Exploration Incorporated field crew where he advanced quickly from trainee to observer to computer to party chief. While in these line positions, he did much to pass on his engineering knowledge and to encourage the many budding geophysicists who came under his influence. This trait stayed with Ed and as he matured professionally so did his interest in continuing education He was one of the first to recognize the -very negative impact of multiple reflections on the interpretive process. He was First Vice-president (program chairman) of the Geophysical Society of Houston and for two years Chairman of its Continuing Education Committee whose duty it was to organize and conduct seminars. He provided an SEG 1982-1983 scholarship, for a student at the University of Oklahoma.

He spent 28 years with the predecessors of Geosource: Petty Ray and Seismic Explorations, Inc. where he retired as assistant manger of operations for the Western Hemisphere. He was then with GeoQuest for .two years and for three years ran Zagst Geophysical Consultants. In addition to SEG and GSH? he was a member o f AAPG and registered geophysicist GP436 of the State of California.

It can be said that Ed had a host of friends and that whether he was Setting the parameters for the acquisition of seismic data on the North Slope, making a feasibility study in Argentina, or hammering out his interpretations of the Eastern Overthrust Belt, his performance was excellent.

He enjoyed the outdoors; his hobby was hunting. In Houston for many years he had a covey of quail that came to be fed twice a day. In Wimberly he fed corn to the many deer who crossed the Blanco River to get in his yard.

Ed died of lung cancer November 7, 1983 at the age of 63.

He is missed by his wife Helen, his daughters Cathy and Jeanne, his sons John and Mike, his grandchildren and his many friends and associates.
