Editor's note: Professor Hans Einstein, a son of the famous physicist Albert Einstein, was a pioneer in river bed-sediment transport, with a detailed account of his life and accomplishments in the book by R. Etterna and C.F. Mutel, Hans Albert Einstein: His Life as a Pioneering Engineer, ASCE Press, 2014, and for a shorter version of the book, the paper by R. Ettema and C.F. Mutel, Hans Albert Einstein: Innovation and Compromise in Formulating Sediment Transport by Rivers, Journal of Hydraulic Engineering, Vol.130, No.6, June 2004, which was published to “mark the hundredth anniversary of the birth of Hans Albert Einstein (1904–1973)”.

Editor's note: Since it is rare to have quality photos of a professor in the act of teaching in the pre-Internet era, particularly taken by a Life photographer, and with space allowed, I took up the offer of Ms. Marlys Ray to also include the above photo, just for the pleasure of looking at these quality photos.
