Robert Mosher

Robert Mosher (born September 27, 1920[1]) was an apprentice to Frank Lloyd Wright who worked on Fallingwater, and is mentioned in Wright's diary's of Fallingwater. NOTE: there are TWO Robert Moshers. One worked with Frank Lloyd Wright, ONLY, the other designed the Coronado Bridge, among other buildings and structures, and met with Frank Lloyd Wright when working with House Beautiful Magazine.[2][3][4]

"Every material has its own eloquent message, its own lyrical song, and no one has made them sing so beautifully as Frank Lloyd Wright." [5]

He is also known for his own works which include the San Diego-Coronado Bridge on which he was the principal architect .[6]

Mosher also was the architect of the University of California, San Diego's John Muir College[7][8] which was built in the late 1960s, and whose powerful concrete architecture represents the focal point of San Diego's modernist design heritage, which has won a recently won a $100,000 grant from the Getty Foundation to protect its distinctive buildings.

"Even at a relatively young age of 40, the college still finds it necessary to devise a program to protect its signature cluster of buildings and connecting courtyards, which have strong ties to local architects," said Susan Smith, Muir College provost.

Smith said the grant will allow UCSD to hire an outside consultant to survey Muir College's architectural heritage and to devise initial steps for a long-term preservation plan. The award is part of a wider Getty program focused on preservation of important architecture at colleges and universities nationwide.
