Article author, Ms. Emily Blackaby, winner of a 2018 AIPG-TX 2018 Ted H. Foss
Scholarship receiving her award. (L-R) Stacy C. Atchley, Ph.D., Professor and Chair of the Department of Geosciences, Baylor University, Emily Blackaby, Glen A. Collier, CPG, Chair of AIPG Texas Section’s Scholarship Committee, and William C. Hockady, Ph.D., Associate Professor, Department of Geosciences, Baylor University (Sponsor).
The Foss Scholarship is awarded to an undergraduate attending a university in Texas whose performance in college to date, outlook, and indicated objectives are exemplary among his or her peers.
The scholarship commemorates the contributions of Dr. Ted H. Foss to Rice University (Ph.D., 1964),to NASA in serving as the Chief of the Geology & Geochemistry Branch of the Science Directorate, Houston and in providing geological training to the original group of astronauts in the mid-to-late 1960s at various places of volcanic interest around the world, in cooperation with the U.S. Geological Survey, to the mineral exploration and mining industry as senior management for projects around the world, to many students while teaching short-courses and seminars,to industry and the environmental consulting field for his invaluable mentoring over the years, and to the AIPG Texas Sections over the many years he was a CPG
