From R4RS (e.g.,,
sub "Introduction", sub "Background", one might pick December 1975:

	The first description of Scheme was written in 1975 [SCHEME75].
	A revised report [SCHEME78] appeared in 1978, which described
	the evolution of the language as its MIT implementation was
	upgraded to support an innovative compiler [RABBIT]. Three
	distinct projects began in 1981 and 1982 to use variants of
	Scheme for courses at MIT, Yale, and Indiana University [REES82]
	[MITSCHEME] [SCHEME311]. An introductory computer science textbook
	using Scheme was published in 1984 [SICP].

	     Gerald Jay Sussman and Guy Lewis Steele Jr. Scheme: an
	     interpreter for extended lambda calculus. MIT Artificial
	     Intelligence Memo 349, December 1975. 

But they'd probably been playing around with it for a while before then...
