Life and work

Principal of Agra College, 1960–1970

Manohar Ray was a mathematician and educationist from Nasigram.[1] Agra College’s official list records his principalship from 1960 to 1970, alongside his doctorates and fellowships in Indian scientific academies.[2]

His research addressed mathematical problems in fluid motion. His paper on an elliptic cylinder moving through a fluid with constant vorticity appeared in Proceedings of the Royal Society A on 3 February 1937.[3]

The Royal Society also preserves Geoffrey Ingram Taylor’s assessment of the revised paper. Received on 31 August 1936, the report recommended publication in full, providing a surviving record of how this work was reviewed.[3]

Dutta includes the mathematician from Nasigram among Ugra Kshatriya intellectual figures, pp. 313–314. “Ray” follows the college and Royal Society records; Dutta uses “Roy.”[1]
