"introduced design patterns"
Did he? I hate to short change Kent, but I would give credit to Gang of four ?

Don't confuse popularizationwith introduction 
No, the contribution of the Gang of four was to popularize the notion of patterns in software development, outside of the already established patterns community which had been developing for at least the eight years prior to its publication.
I'm pretty sure that the credit does in fact to to Kent (and Ward Cunningham), who as far as I know were the first to introduce patterns to software development, based on the work of Christopher Alexander in architecture and community design. They first presented this during OOPSLA in 1987 and their paper is even referenced in the bibliography of this article. The patterns community had already emerged years prior to the publication of Gamma, Helm, Ralph Johnson, and Vlissides, "Design Patterns". in 1995.
Kent started writing a column on "Smalltalk Patterns" in "The Smalltalk Report" in 1993, a fact which is acknowledged on page 357 of "Design Patterns." These later formed the basis of his "Smalltalk Best Practice Patterns" book

Implementation Patterns 
Completely off topic, but does anyone know what Implementation Patterns is like? Is it merely a generic version of Smalltalk Best Practice Patterns? → 22.214.171.124 20:23, 2 November 2007 (UTC)
Sorry folks, the whole introduction to this entry is completely incoherent to anyone who isn't a software-type person (i.e. me). Just read the first paragraphs, I'm sure you'll see what I mean. What is this guy, a software developer? What? Silky Slim (talk) 11:50, 11 February 2008 (UTC)
The publication date for Extreme Programming Explained is listed as 2005. I checked the history and see that it's because a second edition is listed. Shouldn't the first edition of books be listed instead? Otherwise it seems to distort the publication timeline which could be confusing to those trying to correlate publication dates with influence on other publications, etc.
The first and second edition of Extreme Programming Explained are very different books. Core concepts are maintained, but the meat of the discussion is different. Since they are vastly different publications shouldn't both be included?
