From 1992 to 2003, Professor Frederick F. Ling held the Earnest F. Gloyna Regents Chair in Engineering at University of Texas at Austin within the Department of Mechanical Engineering, and was Associate Director of the Engineering Manufacturing Systems Center. Here Fred initiated a national thrust for Diagnostics and Maintenance Science research, which has benefitted multiple U.S. universities. Fred served on many public policy committees, including a City of San Antonio committee to commission Kelly Air Force Base as a civilian manufacturing center after its closure. In addition to teaching, scholarship, and spearheading research thrusts, Fred actively mentored and advised numerous undergraduates, graduate students, and faculty, including me. He enjoyed helping and mentoring his junior colleagues. Fred led quietly and without pretension. He would coax his junior colleagues into new areas of teaching and research in which they were uncomfortable, but inevitably these moves resulted in long-term benefits. Fred had uncanny foresight seeing science and engineering research opportunities decades before others, and he guided the research funding agencies to these opportunities. Fred was generous with his time and money. After lunch or dinner, he would pounce on the check. After he retired from University of Texas, Fred was awarded the title of Professor Emeritus at University of Texas. Fred was a true gentleman and scholar, a man of utmost integrity and wisdom, a founder of modern tribology, and a joy to know and work with.
