Christopher Alexander

Christopher Wolfgang John Alexander (4 October 1936 – 17 March 2022) was an Austrian-born British-American architect and design theorist. He was an emeritus professor at the University of California, Berkeley. His theories about the nature of human-centered design have affected fields beyond architecture, including urban design, software design, and sociology. Alexander designed and personally built more than 200 buildings, both as an architect and a general contractor.

In software, Alexander is regarded as the father of the pattern language movement. According to creator Ward Cunningham, the first wiki—the technology behind Wikipedia—led directly from Alexander's work. Alexander's work has also influenced the development of agile software development.

In architecture, Alexander's work is used by a number of different contemporary architectural communities of practice, including the New Urbanist movement, to help people to reclaim control over their own built environment. However, Alexander was controversial among some mainstream architects and critics, in part because his work was often harshly critical of much of contemporary architectural theory and practice.^{[page needed]}

Alexander is best known for his 1977 book A Pattern Language, a perennial seller some four decades after publication. Reasoning that users are more sensitive to their needs than any architect could be, he collaborated with his students Sara Ishikawa, Murray Silverstein, Max Jacobson, Ingrid King, and Shlomo Angel to produce a pattern language that would empower anyone to design and build at any scale.

His other books include Notes on the Synthesis of Form, A City is Not a Tree (first published as a paper and re-published in book form in 2015), The Timeless Way of Building, A New Theory of Urban Design, The Oregon Experiment, the four-volume The Nature of Order: An Essay on the Art of Building and the Nature of the Universe, about his theories of "morphogenetic" processes, and The Battle for the Life and Beauty of the Earth, about the implementation of his theories in a large building project in Japan.

Alexander was born in Vienna, Austria to his Catholic father, Ferdinand Johann Alfred Alexander, and Jewish mother, Lilly Edith Elizabeth (née Deutsch) Alexander. As a young child, Alexander emigrated in fall 1938 with his parents from Austria to England, when his parents were forced to flee the Nazi regime.^{[page needed]} In England, his parents worked as German language teachers. Alexander spent much of his childhood in Chichester and Oxford, England, where he began his education in the sciences. He moved from England to the United States in 1958 to study at Harvard University and Massachusetts Institute of Technology. He moved to Berkeley, California in 1963 to accept an appointment as Professor of Architecture, a position he would hold for almost 40 years. In 2002, after his retirement, Alexander moved to Arundel, England, where he continued to write, teach and build up to the time of his illness and death. Alexander was married to Margaret Moore Alexander, and he had two daughters, Sophie and Lily, by his former wife Pamela Patrick. Alexander held both British and American citizenship.^{[citation needed]}

On 17 March 2022, Alexander died of pneumonia in his home in Binsted, England.

Alexander attended the Dragon School in Oxford and then Oundle School. In 1954, he was awarded the top open scholarship to Trinity College, Cambridge, in chemistry and physics, and went on to read mathematics. He earned a Bachelor's degree in Architecture and a master's degree in mathematics. He took his doctorate at Harvard (the first PhD in Architecture ever awarded at Harvard University). His dissertation "The Synthesis of Form: Some Notes on a Theory" was completed in 1962. He was elected fellow at Harvard. During the same period he worked at MIT in transportation theory and computer science, and worked at Harvard in cognition and cognitive studies.
