Professor Stanley Corrsin completed his undergraduate work at the University of Pennsylvania and received his Ph.D. in aeronautics at the California Institute of Technology. He was the first graduate student of Hans Liepmann, a pioneer in fluid mechanics. Professor Corrsin joined the Johns Hopkins aeronautics department in 1947 and was affiliated with the Departments of Biomedical Engineering, Chemical Engineering, Mechanical Engineering, Mechanics, and Mechanics and Materials Science. He served as department chair of mechanical engineering from 1955 to 1960. In 1979, he helped found the Department of Chemical Engineering. In 1981, he was appointed to the Theophilus Halley Smoot Chair of Engineering at Johns Hopkins.
Professor Corrsin was an American Academy of Engineering Fellow and received the Distinguished Alumni Award from the University of Pennsylvania. He was also awarded the von Karman Medal of the American Society of Civil Engineers. Though he received many honors as a researcher, he always preferred the title “Professor of Fluid Mechanics.”
His death in 1986 prompted the initiation of the Stanley Corrsin Lecture in Fluid Mechanics. The Lecture series is made possible by the Stanley Corrsin Fund, established at Johns Hopkins by friends and former students of Professor Corrsin.
Dr. Holtz started his Government career in 1934 as a Junior Chemist in the Navy Department and transferred to the bureau of mines as Associate Gas Engineer on December 1, 1936. Because of his capabilities, Bureau assignments were varied with increasing responsibilities. Starting with research on gaseous products from explosives, he also organized, directed and worked with other Bureau scientists conducting pioneering research on diesel exhaust products. This work led to the establishment of the present Bureau of Mines Schedules 22, 24 and 31 for diesel mine locomotives, mobile-diesel-powered equipment for non-coal mines, and mobile-diesel-powered equipment for gassy non-coal mines and tunnels.
Dr. Holtz’s publication of Bureau of Mines R.I. 5616, “Safety with Mobile-Diesel-Powered Equipment Underground” is used internationally as a basic reference for diesel performance and operational characteristics in mines and tunnels. His experience with explosives was utilized during World War II in the conduct of a variety of research projects on explosives and propellant systems. Following the war, he assumed additional administrative responsibilities at the Bureau of Mines installation in Grand Forks, North Dakota; Morgantown, West Virginia, and Pittsburgh, Pennsylvania.
For his eminent career in Bureau of Mines and his outstanding achievement in the field of safety with diesel-powered equipment, Dr. Holtz was granted the highest award of the Department of the Interior, its Distinguished Service Award, on June 8, 1967.
Dr. Schwarz attended the Johns Hopkins University, where he earned a bachelors, masters and doctoral degree in 1951, 1955, and 1957 in chemical engineering. As an undergraduate, he starred on the Hopkins football team as a defensive end and later served as line coach while continuing graduate studies.
For his doctoral work, Dr. Schwarz studied with the late Stanley Corrsin, one of the leading turbulence experts of his generation. After receiving his Ph.D., Schwarz went to Stanford University, where his 1963 article, co-authored with Carl Gibson, is considered a landmark in the field. In 1968, Dr. Schwarz returned to Johns Hopkins to join Stan Corrsin after having been promoted to professor of mechanics.
At Hopkins, the interdisciplinary nature of the then-Department of Mechanics provided fertile ground for Schwarz’s other research interests, including acoustics, the mechanics of swallowing, biophysics, and bacteria that cause drag when they attach to sea vessels. In 1977, Schwarz developed a plan for reestablishing chemical engineering at Hopkins and served as the re-established department’s chair from 1979-1981.
Schwarz also loved sailing and skippered his boat, Good Times, to victory in a division of the 1993 Governor’s Cup yacht. The legacy of Bill Schwarz lives on through his students who have gone on to lead successful careers.
