A second-generation surveyor, Dr. Elgin was raised in his father's surveying business in Rolla, Missouri. After serving as an Army helicopter pilot in Vietnam he returned to Rolla and received the degrees B.S. and M.S. in civil engineering from the University of Missouri-Rolla (UMR). After working in private surveying practice for several years he attended the University of Arkansas and received the degree Doctor of Philosophy. Formerly an Assistant Professor of Civil Engineering at UMR, in 1984 he purchased and now also operates the family surveying business Elgin Surveying & Engineering, Inc. in Rolla, Missouri. He currently is Adjunct Professor of Civil Engineering at UMR, and is a former member of the Missouri Board for Architects, Professional Engineers and Land Surveyors.

Dr. Elgin is a past president of the Missouri Association of Registered Land Surveyors (MARLS), and edited the "Missouri Surveyor" for several years. He was named the 1983 Young Engineer of the Year by the Missouri Society of Professional Engineers. Dr. Elgin is a member of ACSM, NSPS, NSPE, MARLS, Chi Epsilon, Tau Beta Pi, and UMR's Order of the Golden Shillelagh and its Academy of Civil Engineering. He collects early American surveying equipment and rides his bicycle.

He received the degrees B.S.C.E. from Washington University (St. Louis), M.S.C.E. from MSM, and Ph.D. from Iowa State.

With a wide academic and consulting background in engineering, surveying, orbital mechanics and astronomy, a few of his more interesting surveying/astronomy consulting projects have included: Consultant to establish precise astronomic coordinates for the Feather Ridge Observatory, consultant in orbital mechanics to develop tracking programs for communication satellites, and consultant on precision alignment of magnet units for a 95 meter radius proton synchrotron.

Dr. Senne is the past vice president of the International Occultation Timing Association which is involved in precise timing of lunar total and grazing occultations by asteroids. (This work is done in cooperation with the U.S. Naval Observatory.)

Author of numerous papers, Dr. Senne is a member of ASPRS, ASCE, ASEE, NSPE, MSPE, The Society of Sigma Xi, Chi Epsilon, Tau Beta Pi, Phi Kappa Phi and American Men of Science. He is a computer "bug."
