What was the reason behind Feynman death?

Richard Feynman, possibly the most brilliant, iconoclastic, and influential theoretical physicist of the postwar generation, died on February 15, 1988, of liposarcoma, a rare form of cancer. He died on a Monday night in Los Angeles.

Feynman was experiencing significant abdominal pains when he went to the hospital and was diagnosed with liposarcoma, a rare form of cancer.

A “very huge” tumor that had crushed one kidney and his spleen was removed by surgeons.

Further procedures were carried out in October 1986 and October 1987.

On February 3, 1988, he was admitted to UCLA Medical Center for the second time.

A ruptured duodenal ulcer caused kidney failure, and he declined to undergo the dialysis that might have prolonged his life for a few months.

His wife Gweneth, sister Joan, and cousin Frances Dalaeue cared for him in his final days until his death on February 15, 1988.

Feynman, who was born on May 11, 1918, is best known for his contributions to the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, the physics of supercooled liquid helium superfluidity, and particle physics, for which he created the parton model.

Feynman shared the Nobel Prize in Physics in 1965 with Julian Schwinger and Shin’ichir Tomonaga for his contributions to the development of quantum electrodynamics.

He was named the seventh-greatest physicist of all time in a survey of 130 eminent physicists globally conducted by the British publication Physics World in 1999.
