Legacy | Commemoration

Institutions, Prizes and Memorials

Ramanujan's name lives through prizes, institutes, memorial houses, museums, stamps and public mathematical culture.

Prizes

The SASTRA Ramanujan Prize and other honors keep his name connected with young mathematical talent.

Institutions

Institutes, university programs and memorial spaces in India and abroad preserve different parts of his legacy.

Public Memory

Commemoration helps the public encounter Ramanujan, but the archive should always bring memory back to the mathematics and historical person.
