- Confidence
- Very low. Born after 1850, so outside the Cox 1926 study. No IQ test result is known.
Chandrasekhar has no test score. 160 is an editorial marker for a theorist who found the limit on white dwarf masses at 19.
Subrahmanyan Chandrasekhar in brief
Subrahmanyan Chandrasekhar was born in Lahore in 1910 and grew up in Madras; his uncle was the Nobel physicist C. V. Raman. He studied at Presidency College, then at Cambridge on a scholarship, and moved to the University of Chicago in 1937, where he stayed for the rest of his career. He worked through stellar structure, radiative transfer, hydrodynamics and black holes, and shared the 1983 Nobel Prize in Physics.
What was Chandrasekhar's IQ?
No test score is known. LifeScore lists about 160 as an editorial marker, range 145 to 175. It rests on the limit he derived at 19, a Nobel Prize and a career of definitive monographs in several areas of astrophysics.
What is the Chandrasekhar limit?
It is the largest mass a white dwarf star can have, about 1.4 times the mass of the Sun. Above it, electron pressure cannot hold the star up and it collapses further, towards a neutron star or a black hole. The limit explains a class of supernovae used to measure the universe.
Why did Eddington reject Chandrasekhar?
At a 1935 meeting of the Royal Astronomical Society, Eddington, the most famous astrophysicist of the day, mocked the idea that stars could collapse without limit. Chandrasekhar, then in his twenties, was humiliated, but later work confirmed his result.

How Chandrasekhar thought
Chandrasekhar combined relativity and quantum statistics in a problem nobody had joined them in before, and he followed the mathematics even when it gave an unwelcome answer. His habit was total mastery: work through a whole field, then write the book on it.
The evidence behind the estimate
An estimate built from the historical record, not a recovered test score.
What supports it
- He derived the white dwarf mass limit in 1930, at 19.
- He shared the 1983 Nobel Prize in Physics.
- His series of monographs are standard references in several fields.
What it cannot prove
- Edmund Stoner and Wilhelm Anderson worked on related calculations.
- Achievement reflects education, opportunity, persistence and collaboration as well as raw reasoning ability.
- An editorial marker is a comparison aid built from achievement, not a measurement, and two careful readers could place it ten points apart.

Psychological profile
Subrahmanyan Chandrasekhar's IQ is represented here by a retrospective estimate of 160, not a verified test result. Subrahmanyan Chandrasekhar is best known for exceptional mathematical physics. The useful question is what the surviving evidence shows, not whether a precise modern score can be recovered.
Disciplined, courteous and austere. He mastered one field at a time, wrote the definitive book on it, then moved on.
The dominant archetype here is The Master. This archetype shapes decision patterns: what feels natural, what creates friction, and what blind spots tend to emerge.
Estimated IQ is 160. This is a rough estimate based on documented accomplishments and contemporary accounts, not a literal measurement.
Key traits

He worked out his famous limit on the sea voyage from India to England in 1930, aged 19.Discipline
Arthur Eddington publicly ridiculed the result in 1935; time proved Chandrasekhar right.Persistence
He edited the Astrophysical Journal for nearly twenty years.
One thing most people do not know
Chandra means "luminous" or "moon" in Sanskrit, which NASA noted when naming its telescope.
