The Nobel Prize's official nomination archive records seven nomination entries for Meghnad Saha across six years: 1930, 1937, 1939, 1940, 1951, and 1955, though he never won the award before passing away in 1956 at the age of 62.
Published in 1920, the Saha ionisation equation describes how temperature and pressure influence the proportion of atoms that lose electrons to become ions. This equation is a fundamental tool that allows astronomers to interpret stellar spectra and determine the physical conditions and elements present in stellar atmospheres.
Meghnad Saha played a significant role in developing the physics department at Allahabad University and the Institute of Nuclear Physics in Calcutta, which was later named the Saha Institute of Nuclear Physics. He also founded the journal Science and Culture and served as its editor until his death.
