History
The concept of a graph reduction that allows evaluated values to be shared was first developed by Chris Wadsworth in his 1971 Ph.D. dissertation. This dissertation was cited by Peter Henderson and James H. Morris Jr. in 1976 page, “A lazy evaluator” that introduced the notion of lazy evaluation. In 1976 David Turner incorporated lazy evaluation into SASL using combinators. SASL was an early functional programming language first developed by Turner in 1972.

Famous quotes containing the word history:
“In nature, all is useful, all is beautiful. It is therefore beautiful, because it is alive, moving, reproductive; it is therefore useful, because it is symmetrical and fair. Beauty will not come at the call of a legislature, nor will it repeat in England or America its history in Greece. It will come, as always, unannounced, and spring up between the feet of brave and earnest men.”
—Ralph Waldo Emerson (1803–1882)
“It is the true office of history to represent the events themselves, together with the counsels, and to leave the observations and conclusions thereupon to the liberty and faculty of every man’s judgement.”
—Francis Bacon (1561–1626)
“When the history of guilt is written, parents who refuse their children money will be right up there in the Top Ten.”
—Erma Brombeck (20th century)
