Meghnad Saha FRS (6 October 1893 – 16 February 1956) was an Indianastrophysicist best known for his development of the Saha ionization equation, used to describe chemical and physical conditions in stars.
Meghnad Saha was born in Shaoratoli village near Dhaka, British India (present Bangladesh). Son of Jagannath Saha, Meghnad Saha belonged to a poor family and struggled to rise in life. During his early schooling he was forced to leave Dhaka Collegiate School because he participated in the Swadeshi movement. His Indian School Certificate was earned from Dhaka College. He was also a student at the Presidency College, Kolkata; a professor at Allahabad University from 1923 to 1938, and thereafter a professor and Dean of the Faculty of Science at the University of Calcutta until his death in 1956. He became Fellow of the Royal Society in 1927. He was president of the 21st session of the Indian Science Congress in 1934.
Saha was fortunate to have brilliant teachers and class fellows. In his student days, Jagadish Chandra Bose, Sarada Prasanna Das and Prafulla Chandra Ray were at the pinnacle of their fame. Amongst his class fellows were Satyendra Nath Bose, Jnan Ghosh and J. N. Mukherjee. In later life he was close to Amiya Charan Banerjee, a renowned mathematician at Allahabad University.
