Introduction
Joël Scherk (French: [jɔɛl ʃɛʁk]; 1946 – 16 May 1980), often cited as Joel Scherk, was a French theoretical physicist who studied string theory and supergravity.
Work
In 1974, together with John H. Schwarz, Scherk realised that string theory was a theory of quantum gravity. In 1978, together with Eugène Cremmer and Bernard Julia, Scherk constructed the Lagrangian and supersymmetry transformations for supergravity in eleven dimensions, which is one of the foundations of M-theory.
He died unexpectedly, and in tragic circumstances, months after the supergravity workshop at the State University of New York at Stony Brook that was held on 27–29 September 1979. The workshop proceedings were dedicated to his memory, with a statement that he, a diabetic, was trapped somewhere without his insulin and went into a diabetic coma.
The high-energy theory library of the Laboratoire de Physique Théorique at École Normale Supérieure (Paris) is dedicated in his honor. A conference in Paris, on 16–20 October 2006, celebrating 30 years of supergravity, was dedicated to Scherk.
