Dijkstra and Dahle may have introduced the the formalism of structured
programming, but it is widely recognized that they were inspired by
Bohm and Jacopini's research.  Dijkstra's 1968 letter to the ACM,
"GO TO Statements Considered Harmful", has only two references:

    1. Wirth, Niklaus, and Hoare C. A. R. A contribution to the
       development of ALGOL. Comm. ACM 9 (June 1966), 413-432.
    2. Bohm, Corrado, and Jacopini Guiseppe. Flow diagrams, Turing
       machines and languages with only two formation rules. Comm. ACM 9
       (May 1966), 366-371.

The use of COBOL cripples the mind; its teaching should, therefore, be
regarded as a criminal offence.
