Pierre Koenig (October 17, 1925 – April 4, 2004) son of a salesman was an American architect who was born in San Francisco, enrolled in architectural studies and received his B. Arch. in 1952 from the University of Southern California.
Koenig worked with Raphael Soriano, among others, and began private practice in 1952. Koenig practiced mainly on the west coast and was most notable for the design of the Case Study Houses No. 21 and 22 in 1960. Both 21 and 22 were constructed on dramatic, otherwise-unbuildable sites.
