Manohar Ray received DSc (1939) from University of Calcutta. He was Postgraduate Lecturer, FC College, Lahore (1936-43); Professor and Head, Mathematics Department (1943-59), Registrar (1959-60) and Principal (1960-70), Agra College, Agra.

Academic and Research Achievements: Ray’s researches were concerned with the flow of fluids, theories of turbulence and flow of compressible fluids. He produced an ingenious solution of the motion of a circular disc by making use of the discontinuous integrals of Weber and Schafheithion and found that the drag for broadside motion is one-and-a half times that for edgeways motion.

Awards and Honours: Professor Ray was elected Fellow of the National Academy of Sciences (India), Allahabad; and President, Mathematics Section, Indian Science Congress (1958-59).
