Odysseys in Technology: How I Became Interested in Programming Languages, lecture by Nikalus Wirth
From abstract: "In 1960, the opportunities for building computers in universities were fading. Computers had become too big, complex, and expensive. The focus shifted to programming and to bringing order into the new subject of software design. Even though this task seemed elusive, mainly because it involved not only designing better languages, but also educating people to make use of such improvements. Nevertheless, for Dr. Wirth, the goal was worthwhile—a goal he pursued for more than three decades, during which time he designed and implemented Algol W, Pascal, Modula-2, and Oberon."
