D.D. Kosambi is best known today for his work on historiography, particularly the book An Introduction to the Study of Indian History. But during his extraordinary life, that was just one of the many roles he played; he was also a mathematician, numismatist, institution builder, Marxist and prolific author.In his new book D.D. Kosambi: One Life, Many Worlds, natural scientist Ram Ramaswamy traces his family and academic life, his journey as a peace activist, his relationships and more. He joins The Wire’s Managing Editor Jahnavi Sen in this episode of BookShook to talk about all of that.
