Serial found of consultancy firms - and one bought by TI. And then wikip says,
"According to Computerworld’s 25th anniversary issue, he was ranked fourth among the 25 individuals who have most influenced the world of computer science."
But I'm outside of the inside-joke: why he gets no love from Edsger W. Dijkstra in the OP.
EDW believed that the real "computer science" is not "selling snake oil," like Object Oriented Design Methods, which he considered a kind of selling "business management" in software. He believed that the real "computer science" is only in developing mathematical methods that enable fundamentally new possibilities by using them. James Martin personifies a "snake oil seller" for him.
By the way the Wikipedia entry for James Martin sounds to me a lot like it was written by James Martin himself. Reading the entry it appears that JM invented all by himself "Information Engineering," "Computer-Aided Software Engineering," and "Rapid Application Development."
All three concepts would anyway be despised by EDW who here implies that academics should work only with Buxton Index of 50.
My attempts to disambiguate at wikipedia and google leave me still feeling out of the loop on this one.
