Christopher Alexander

Christopher Alexander is an Austrian-born British-American architect and design theorist who served as Professor Emeritus of Architecture at the University of California, Berkeley, and was President of the Center for Environmental Structure. He is best known for his 1977 book A Pattern Language, which proposed a practical architectural system empowering ordinary people to design and build at any scale, and his work on the nature of human-centered design has influenced fields beyond architecture including urban design, software development, and sociology. He designed and built more than 200 buildings across five continents over his career. Alexander passed away on March 17, 2022, at his home in Sussex, England.
