Architecture in Los Angeles has generated praise, innovation and scorn from the beginning. Great architects have designed important structures for Los Angeles, and altered the city’s landscape in ways residents do not always understand. This SDG will study selected Los Angeles architects and their unique architectural contributions to the city during the 20th century, starting with craftsmen architects Greene & Greene and ending with Frank Gehry. We will utilize the survey of L.A. architecture published by architect and UCLA professor Charles Moore, former Dean of Yale Architecture School, entitled The City Observed: Los Angeles; weekly topics will require some research by presenters from the internet, or from sources identified in Moore’s book, regarding the architects and works that our group will examine.
