Christopher Alexander(1936-) 克里斯托弗•亚历山大

(born October 4, 1936 in Vienna, Austria) is an 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 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.

The processes of nature can make an infinite number of human faces, each one unique, each one beautiful. The same is true for daffodils, streams, and stars. But man-made creations-especially the towns and buildings of the 20th century-have only occasionally been really good, more often mediocre, and in the last 50 years have very often been deadly. What is the reason for the difference?

In Book 2, Alexander explains in detail the kinds of process that are capable of generating living structure. The unfolding of living structure in natural systems is compared to the unfolding of buildings and town plans in traditional society, and then contrasted with present-day building processes.

The comparison reveals deep and shocking problems which pervade the present day planning and construction of buildings. Pervasive changes are needed to create a world in which living process-and hence living structure-are possible; these are changes which are ultimately attainable only through a transformation of society.

It is the use of sequences which makes it possible for each building to become unique, exactly fitted to its context, and harmonious. And it is also this use of sequences which makes it possible for people to participate effectively in the layout of their own buildings and communities.
