&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;The Hillside Group is a group of software developers that gathered to develop [[Erich Gamma]]'s use of object-oriented patterns, which was in turn inspired by [[Christopher Alexander]]'s use of patterns in architecture.&lt;br /&gt;
&lt;br /&gt;
In August of 1993, [[Kent Beck]] and [[Grady Booch]] sponsored a mountain retreat in Colorado, inviting [[Ward Cunningham]], [[Ralph Johnson]], [[Ken Auer]], [[Hal Hildebrand]] and [[Jim Coplien]]. The Group agreed to build on [[Erich Gamma]]'s work studying object-oriented patterns, but proposed to use patterns in a ''generative'' way, as [[Christopher Alexander]] used patterns in architecture, thus distinguishing the creative use of patterns from ''Gamma patterns'', which captured observations. The Group held these discussions on the side of a hill, whence the name.&lt;br /&gt;
&lt;br /&gt;
The HillsideGroup met again in April 1994 to plan the first PLoP conference, joined this time by [[Richard Gabriel]]. The PLoP conference was held in August 1994 near Monticello, Illinois. The PLoP proceedings came out in May 1995 as Pattern Languages of Program Design.&lt;br /&gt;
&lt;br /&gt;
Other members of the Hillside Group include [[Desmond DeSouza]] and [[Norm Kerth]].&lt;br /&gt;
&lt;br /&gt;
When [[Ward Cunningham]] created [[WikiWikiWeb]] in early 1995, he posted an invitation to the members of the [[PatternsList]], many of whom were members of the Hillside Group.&lt;br /&gt;
&lt;br /&gt;
The Hillside Group has been incorporated as an educational non-profit. It has sponsored various conferences since the first Plop Conference (EuroPlop, ChiliPlop, KoalaPlop, Mensore PLoP, SugarloafPLoP and UP97) and has been responsible for the PatternLanguagesOfProgramDesign series of books.&lt;br /&gt;
