(Thematic - Business) Silicon Valley Genealogy, Hoefler & Yelverton, 1986 An chart for the business ecosystem as it evolved in Silicon Valley. As with so many "new" innovations they have close roots to a successful predecessor, or build right on the foundations of the previous infrastructure, and indeed the first company shown is "Bell Telephone Laboratories" in 1947. From the great intellectual pool of inventors and scientists at Bell came numerous important figures like Claude Shannon, or William Shockley, and it was Schockley that would help anchor tech in the South Bay Area. From his firm would flee the disaffected employees, the "traitorous eight", as Shockley called them, to found "Fairchild Semiconductor", and from there on new firms would sprout and momentum would build. This chart well documents the explosive growth throughout the 1960's and 70's, and the businesses of the 1980's that still persist today (Atmel, Xilinx, etc). A great look at the hardware based underpinnings of early Silicon Valley and how it branched and changed. Condition is very good, bordering on crisp. Overall size is approximately 24 x 36 (inches)
