Robert “Bob” MacDonald (1941–2014) was born in Detroit, Michigan, to Claude and Ruth MacDonald. He attended public schools in Royal Oak and graduated from Kimball High School where he excelled in trumpet and was voted “Most Likely to Succeed.” In 1963, Bob received Bachelor of Science degrees in Chemical and Metallurgical Engineering from the University of Michigan (during which time he also performed with the marching band). While there, Bob met Martha Varnell, a graduate music student, and they married in 1962. After five years as a reservoir engineer with Michigan Consolidated Gas, he accepted an offer from Professor Keith Coats to come to The University of Texas at Austin as a graduate student in the Petroleum Engineering department. Bob, Martha and their two children, Robert and Richard, loaded up a U-Haul van and moved to Austin in 1968.

Ken Nelson was born in Austin, Texas, in 1948 and graduated from Austin High School in 1966. Due to exposure to the oil industry when in elementary school, he enrolled in the Petroleum Engineering department at The University of Texas at Austin and graduated with a Bachelor of Science with Highest Honors in 1970. Several logging courses and meetings with Dr. Sylvain Pirson instilled a great interest in geology during his undergraduate years. He began employment with Pan American Petroleum in Midwest, Wyoming, in 1971 as a production and development engineer and took an educational leave of absence to return to UT Austin to earn a Master of Science in Petroleum Engineering in 1973 while working for the Texas Petroleum Research Committee.

Dr. Myra Dria is founder, president and CEO of Pearl Resources LLC, which has operated in the Delaware Basin since 2011. A Texas-registered professional engineer, Myra also founded Opal Resources in 2007 and served as president and CEO while it operated in the Midland Basin as a co-venture with Goldman Sachs until its first asset sale to W&T Offshore in 2011. In 2018, she was named to Hart Energy’s inaugural “25 Most Influential Women in Energy” list. Across her career with rigor and imagination, Myra applied an insatiable appetite for learning and challenging the “norm.” She earned a Case Western Reserve University BS engineering degree (polymer), and in the late 1970s, the Sohio engineer traveled to Prudhoe Bay, Alaska, contributing to establishing standards for seawater injection in the 2 MMBWPD Prudhoe Bay waterflood. This sparked her interest in facility design and downhole formation damage and led her to earn a PhD in Petroleum Engineering with advisors Dr. Larry Lake and Dr. Robert Schechter at UT Austin.
