"Demolition has already begun on a row of buildings along San Antonio Road, including the International Halal Market and the Barron Park Plumbing Supply sites. The unassuming-looking market was the former site of Shockley Semiconductor a seminal, albeit unsuccessful, business credited with kicking off the silicon chip industry in the South Bay and considered by many to be the true birthplace of Silicon Valley. As of now, the only mark left of the former building is a signpost mounted years ago summarizing the history of the Shockley site.
As part of their plans, Geiser said the finished development would include a variety of silicon-transistor-themed artwork as well as a plaque and photos to commemorate the Shockley building. (http://www.paloaltoonline.com/news/2015/06/01/big-changes-af...)
