Satyendranath Bose, Indian physicist

was a student of J. C. Bose in Calcutta, and clarified the relation between waves and particles by deriving the Planck distribution from the statistical mechanics of electromagnetic waves; Einstein saw in his work the reconciliation of the concepts of waves and particles, provided that the particles of light are indistinguishable, leading to a new idea in the statistics of particles, now called Bose-Einstein statistics.

I met S. N. Bose in 1958, introduced to me by Abdus Salam; it must have been during the visit of Bose to London on the occasion of the election of Bose to the Royal Society; see the nice article.
