Don C. Hoefler (c. 1922 – April 15, 1986) was an American journalist, well-known for using the term "Silicon Valley" for the first time in print. His friend Ralph Vaerst suggested the name "Silicon Valley" in a series of articles entitled "Silicon Valley, USA" in the weekly trade newspaper Electronic News starting on January 11, 1971.
From the mid 1970s until his death in 1986, Hoefler published a newsletter called "Microelectronics News," which was the definitive "tabloid" of the emerging American semiconductor industry. The Smithsonian's National Museum of American History has most issues of the newsletter available for viewing on the internet.
