Lecture notes, circulated for the Summer School on Computer Programming, Copenhagen, August 1967, duplicated typescript with manuscript corrections and revisions, 17 pages.

The lectures were originally given from these notes, which were the basis for all subsequent written versions.

This was a course of lectures given at the International Summer School in Computer Programming, Copenhagen, August 1967. Publication of the Proceedings was held up by editorial dilatoriness for so long that it was shelved, and Strachey continued to revise and rewrite his paper in the hope of having it published elsewhere as an extended journal article or a monograph. It remained unpublished, though some 250 copies were privately circulated.

Strachey described Fundamental Concepts as 'an important paper; it describes the basic principles underlying computing in a relatively unmathematical manner'.
