R is a dialect of the S language that was developed in 1976 by Rick Becker and John Chambers at the Bell Laboratories.
Rick Becker gave an excellent keynote talk “Forty Years of S” at the UseR!2016 conference:
Rick Becker @ UseR!2016 where he talked about the development of the S language that gives explanations for many characteristics of R as we know it, including “<-” assignment operator.
In 1993 Bell Labs gave StatSci (later Insightful Corp.) an exclusive licence to develop and sell the S language. Insightful sold its implementation of the S language under the product name S-PLUS.

In the early nineties at the University of Auckland in the Department of Statistics R was created by Ross Ihaka and Robert Gentleman.
They used GNU General Public License to make R open source free software.

Currently R is developed by the R Development Core Team, of which John Chambers is a member.
