Professor Anatol Roshko Passes Away
Anatol Roshko (MS '47, PhD '52), Theodore von Kármán Professor of Aeronautics, Emeritus, at Caltech, passed away on January 23, 2017. Known for his research in several areas of gas dynamics and fluid mechanics, Professor Roshko made contributions to problems of separated flow, bluff-body aerodynamics, shock-wave boundary-layer interactions, shock-tube technology, and the structure of turbulent shear flows. With pioneering aerodynamics researcher Hans Liepmann, he coauthored the widely used textbook Elements of Gasdynamics, published in 1956. [Caltech story]
Professor Rolf Sabersky Passes Away
Rolf H. Sabersky, Professor of Mechanical Engineering, Emeritus, passed away on October 24, 2016 at the age of 96. Professor Sabersky joined the faculty in 1949 having obtained his BS ’42, MS ’43, and PhD ’49 from Caltech in Mechanical Engineering. He became professor emeritus in 1988. He worked with luminaries throughout his distinguished career including Theodore von Kármán at Aerojet. James Van Allan sought his expertise for the development of the Ajax and Bumblebee rocket programs. Professor Sabersky made pioneering contributions to our understanding of boiling heat transfer, free convection, granular flows, and indoor air quality. He taught courses in thermodynamics, fluid mechanics, and heat transfer. He was renowned for his commitment to education, mentoring, and promoting diversity. He was the author of two popular textbooks, Elements of Engineering Thermodynamics, and Fluid Flow: A First course in Fluid Mechanics, which he coauthored with Professor Allan Acosta. He received the Heat Transfer Memorial Award from the American Society of Mechanical Engineers in 1977.
