I had the privilege of spending a great deal of time with Prof. Dhawan. He could hold the listener enthralled because of the logical, intellectual acumen he could bring to bear on his analysis of any subject. He had an unusual combination of degrees—a B.Sc. in Mathematics and Physics, an M.A. in English Literature, B.E. in Mechanical Engineering, M.S. in Aeronautical Engineering followed by a Ph.D. in Aeronautics and Mathematics from the California Institute of Technology (Caltech) in USA.
