Herbert Marshall McLuhan was born on this day, July 21, in 1911 (d. 1980). McLuhan was a Canadian philosopher whose work is among the cornerstones of the study of media theory. He coined the expression “the medium is the message” in the first chapter in his Understanding Media: The Extensions of Man, and the term “global village.” He predicted the World Wide Web almost 30 years before it was invented. McLuhan was photographed by Karsh in 1967 and 1974.
