High Quality Content by WIKIPEDIA articles! Christopher Wolfgang Alexander (born October 4, 1936 in Vienna, Austria) is a registered architect noted for his theories about design, and for more than 200 building projects in California, Japan, Mexico and around the world. Reasoning that users know more about the buildings they need than any architect could, he produced and validated (in collaboration with Sarah Ishikawa and Murray Silverstein) a "pattern language" designed to empower anyone to design and build at any scale. Alexander is often overlooked by texts in the history and theory of architecture because his work intentionally disregards contemporary architectural discourse. As such, Alexander is widely considered to occupy a place outside the discipline, the discourse, and the practice of Architecture. In 1958 he moved from England to the United States, living and teaching in Berkeley, California from 1963. He is professor emeritus at the University of California, Berkeley. Now retired (though still active), he is based in Arundel, Sussex, UK.
