Meghnad Saha FRS (6 October 1893 – 16 February 1956) was an Indian astrophysicist best known for his development of the Saha ionization equation, used to describe chemical and physical conditions in stars. Meghnad Saha's best-known work concerned the thermal ionisation of elements, and it led him to formulate what is known as the Saha equation.
The expression was developed by the Indian astrophysicist Meghnad Saha in 1920, and later (1923) by Irving Langmuir.

During his early schooling he was forced to leave Dhaka Collegiate School because he participated in the Swadeshi movement.

Saha Institute of Nuclear Physics

Institute of Nuclear Physics
Saha also invented an instrument to measure the weight and pressure of solar rays and helped to build several scientific institutions, such as the Physics Department in Allahabad University and the Institute of Nuclear Physics in Calcutta. A lasting memorial to him is the Saha Institute of Nuclear Physics, founded in 1943 in Kolkata.
The institute is named after the famous Indian physicist Meghnad Saha.

Planning Commission (India)

He was on his way to the office of the Planning Commission in Rashtrapati Bhavan, when he collapsed a few yards away from there.
Rudimentary economic planning, deriving from the sovereign authority of the state, was first initiated in India in 1938 by Congress President and Indian National Army supreme leader Netaji Subhash Chandra Bose, who had been persuaded by Meghnad Saha to set up a National Planning Committee.

Indian Physical Society

He was the leading spirit in organizing several scientific societies, such as the National Academy of Science (1930), the Indian Physical Society (1934), Indian Institute of Science (1935).
It was formally established in 1934 by pioneering Indian physicist Meghnad Saha.
