Christopher Alexander (1936–2022) and Joseph Rykwert (b. 1926) were two giants of 20th century architectural theory who began their work in England and eventually created lasting legacies at two great American architectural schools: the University of California at Berkeley (Alexander) and the University of Pennsylvania in Philadelphia (Rykwert). Their careers not only coincided with a critical period of social and cultural research among designers and urbanists, but in many ways continue to inspire the current generation of committed critics of late capitalist development on our imperiled planet. Yet to many they are too little known.
