Historical Footnote on Design Patterns

When it rains, it pours. I recently attended an excellent talk on "Design Patterns Reconsidered" by Alex Miller. Around the same time, I was listening to a Software Engineering radio podcast (on Adrenalin Junkies) and heard a comment that merits amplification.

Many people know (or would know, if they attended Alex's talk) that the seminal book, Design Patterns, was heavily influenced by books on architecture by Christopher Alexander. In Design Patterns, the now-famous Gang of Four certainly discuss Alexander, and list patterns-based literature of the era, vis-a-vis software architecture -- but there isn't much on the semantic gap between architecture and computer science. How did we discover Alexander in the first place?

On the podcast, a woman points out that Peopleware is one of the first known books on software to reference Alexander's works (though note that the context is organizing office space).

Tom deMarco acknowledges the comment, but states that Edward Yourdon was a major factor in bringing the book into consciousness of IT (in the early 1970s). Though he can only comment for himself (and not the Gang of Four), deMarco goes on to say that he owes "a personal debt" to Yourdon.

Perhaps, we all owe thanks?
