Ward Cunningham, American computer programmer, developed the first wiki
Howard G. Cunningham (born May 26, 1949) is an American computer programmer who developed the first wiki and was a co-author of the Manifesto for Agile Software Development. A pioneer in both design patterns and extreme programming, he started coding the WikiWikiWeb in 1994, and installed it on c2.com (the website of his software consultancy) on March 25, 1995, as an add-on to the Portland Pattern Repository. He co-authored (with Bo Leuf) a book about wikis, entitled The Wiki Way, and invented the Framework for Integrated Tests.

Cunningham was a keynote speaker at the first three instances of the WikiSym conference series on wiki research and practice, and also at the Wikimedia Developer Summit 2017.
