Those of us from Bihar/Jharkhand and into science have all heard about the legend of the man.
Brilliant math mind but disturbed due to mental illness. Passed away in Patna today in poverty.
Vashishth Narayan studied from Netarhat school in Ranchi, which is even today one of the top most (if not the best) school in Jharkhand.
His adviser was John L Kelley, who is one of the most prominent topologists ever.
Kelley literally "wrote the book" on topology that every kid reads in 1st year today.
Hilbert spaces are one of the key notions that connect mathematics to physics.
He published his work in the very highly regarded Pacific Journal of Mathematics in 1974.
However, he was constantly tormented by mental illness and could not live up to his potential, withdrawing from the world and becoming a recluse.
The government of Bihar briefly appointed him as a faculty member at a university in Madhepura.
He finally breathed his last in Patna today.
