How to find the "HP Garage", and other interesting places in and around the Valley...

Taken from http://ohp.parks.ca.gov/landmarks/santa_Clara.htm:

NO. 1000 SITE OF INVENTION OF THE FIRST COMMERCIALLY PRACTICABLE INTEGRATED CIRCUIT - At this site in 1959, Dr. Robert Noyce of Fairchild Semiconductor Corporation invented the first integrated circuit that could be produced commercially. Based on 'planar' technology, an earlier Fairchild breakthrough, Noyce's invention consisted of a complete electronic circuit inside a small silicon chip. His innovation helped revolutionize 'Silicon Valley's' semicondutor electronics industry, and brought profound change to the lives of people everywhere. Location: 844 E Charleston Rd, Palo Alto

NO. 836 PIONEER ELECTRONICS RESEARCH LABORATORY - This is the original site of the laboratory and factory of Federal Telegraph Company, founded in 1909 by Cyril F. Elwell. Here, Dr. Lee de Forest, inventor of the three-element radio vacuum tube, devised the first vacuum tube amplifier and oscillator in 1911-13. Worldwide developments based on this research led to modern radio communication, television, and the electronics age. Location: In sidewalk, SE corner of Channing Ave and Emerson St, Palo Alto

NO. 952 SITE OF WORLD'S FIRST BROADCASTING STATION - On this corner stood the Garden City Bank Building, where Charles D. Herrold established Station FN, the first radio broadcasting station in the world. As a pioneer in wireless telephony (radio), Herrold established the first station in 1909 to transmit radio programs of music and news to a listening audience on a regular basis. Location: SW corner of First and San Fernando Sts, San Jose

NO. 976 BIRTHPLACE OF SILICON VALLEY - This garage is the birthplace of the world's first high-technology region, 'Silicon Valley.' The idea for such a region originated with Dr. Frederick Terman, a Stanford University professor who encouraged his students to start up their own electronics companies in the area instead of joining established firms in the East. The first two students to follow his advice were William R. Hewlett and David Packard, who in 1938 began developing their first product, an audio oscillator, in this garage. Location: 367 Addison Ave, Palo Alto
