Heterotic string theory was first developed by what American theoretical physicist and string theorist who was awarded the 2004 Nobel Price in Physics along with Frank Wilczek?
Heterotic string theory In string theory, a heterotic string is a closed string (or loop) which is a hybrid ('heterotic') of a superstring and a bosonic string. There are two kinds of heterotic string, the heterotic SO(32) and the heterotic "E" × "E", abbreviated to HO and HE. Heterotic string theory was first developed in 1985 by David Gross, Jeffrey Harvey, Emil Martinec, and Ryan Rohm (the so-called "Princeton String Quartet"), in one of the key papers that fueled the first superstring revolution.
