* Lewis Lomax Nettleton (1896-1988) a pioneering geophysicist, Maurice Ewing Medal recipient. He served as the 1948-1949 SEG President. Dr. Nettleton served as the Editor of ''Geophysics'' in the years 1945-1946 and 1946-1947. The Society is privileged to honor Dr. Lewis Lomax Nettleton with its eleventh honorary membership. Such an honor could not be more appropriate, for here we have a pioneer of the geophysical industry and a bulwark of our own Society which he has served most actively for more than twenty years. Known as the "man who wrote the book" or as "Mr. Salt Dome," he personifies our profession and may aptly be called "Mr. Geophysics.". Dr. Nettleton was born in a small town of western Idaho, Nampa, on June 24, 1896. His undergraduate courses were completed at the University of Idaho with a Bachelor of Science degree in physics in 1913. Subsequently he received further degrees in physics at the University of Wisconsin, a Master of Science in 1921 and a doctorate in 1923. While at Wisconsin, he was an assistant on the staff of the physics department. With the completion of his formal education, he began his professional career as a physicist in the research department of the Union Switch and Signal Company in Pittsburgh. Patent applications reveal his developing apparatus for railway-traffic-control during this period. The year 1928 found Dr. Nettleton embarking on his geophysical career with Gulf Research and Development Co. where he afterwards became chief of the gravity section. In an amazingly short time he published, in 1934 actually, his concept of the genesis of salt domes, "Fluid mechanics of salt domes," a concept which is fundamental to and of profound influence upon the entire general subject of structural geology as well as the more restricted field of geophysical prospecting. During continued service with Gulf he quite quickly developed fluid models illustrating the growth of salt domes by reason of the relative buoyancy of a substratum of salt of lower density. Dr. Nettleton's ability to think with originality and clarity is manifested in his publications. His geophysical papers led directly to his departure from Gulf in 1946 to become a partner in Gravity Meter Exploration Company of Houston, Texas. Dr. Schumacher had resigned his partnership. The two remaining partners, Mr. Pagan and Mr. Saville, simply began reading geophysical literature to find a candidate for their new technical partner, and their search ended in the selection of Dr. Nettleton. He has remained in the capacity of a partner in GMX until this time. Dr. Nettleton's contributions to our profession extend far beyond his great commercial successes into the scientific backbone of geophysics by reason of his very significant publications and his great service to our Society. His writing ability served us in great stead during 1945, 1946, and 1947 when he was our Editor. By way of further service, the Society elected him Vice-President in 1947 and President in 1948. The publication that has made him an acquaintance of all of us in our very embryonic stage is his textbook, Geophysical prospecting for oil, published in 1940. Of next pre-eminence are his articles on the genesis of salt domes, the 1943 paper which describes the model experiments of salt dome towage. Dr. Nettleton has also published significant papers concerning the reduction of data, the calculations of gravity and magnetic fields, and the general subject of residual anomalies. You have perhaps noted Dr. Nettleton's successful application of physics to geologic problems. Perhaps his most unusual achievement is this mastery of geology. Without having had any formal training in geology, he has served the Geological Society of America for three years as a member of its projects committee, the committee which screens the applications for funds for research projects. In addition he has been one of four civilian members on the panel on geology, of the committee on geophysical sciences of the Defense Department's Research and Development Board. These facts illustrate his never-ending effort to correlate geophysics and geology--to use geophysics as a geologic tool. The outstanding factor in his career is his insatiable curiosity, and great intellectual power scientifically trained. This ability and curiosity have influenced all geophysicists and will continue to influence all future geophysicists, because it is a mark of his greatness that his spoken and written words are words of truth. Such is the product of a fine mind placed in a man of supreme moral and intellectual honesty. Such is a man upon which our very profession is based. This is a great moment for the Society, for Dr. Nettleton, and for the speaker who is simultaneously experiencing great humility and honor in bestowing the Society's eleventh honorary membership on Dr. Lewis L. Nettleton. (SEG Wiki).
