The Free On-line Dictionary of Computing (30 December 2018):

Mel Kaye

    The hero of The Story of Mel, a Real Programmer.
   The preface to the manuals for the Royal McBee LGP-30 ACT
   1 (Algebraic Compiler and Translator) compiler (dated
   1959) contain the following attribution from Clay S. Boswell,
   Jr. (apparently ACT 1's designer):

    I wish to acknowledge my appreciation to the many people who
    offered suggestions and criticisms of the ACT 1 System.  In
    particular, Mel Kaye of Royal McBee who did the bulk of the
    programming.
