Jay Last, a pioneer who founded Fairchild Semiconductor, which laid the technical, financial, and cultural foundation for Silicon Valley, dies at 92
He and seven others left the Shockley Semiconductor Laboratory to create their own silicon company, Fairchild Semiconductor … Tweets: @vypointjch , @mattblaze , @jacquiemcnish , @aadetugbo , and @andreasharsono Tweets: John C Hollar / @vypointjch : Hail and farewell to Jay Last, Ph.D, of the Traitorous Eight You and your colleagues changed the world, Jay So happy to see my friend @dcbrock quoted in the @nytimes story.

Context & Ripple Effects
Jay Last was one of the Traitorous Eight who walked out of [[entity:the Shockley Semiconductor Laboratory|Shockley Semiconductor Laboratory]] to found Fairchild Semiconductor, the company credited with laying the technical, financial, and cultural groundwork for Silicon Valley. His death lands amid a string of farewells to that founding cohort — Bill Campbell in 2016 and, per the related coverage, Intel co-founder Gordon Moore — thinning the ranks of people who personally built the Valley's origin story.
The timing also sharpens a contrast the coverage has been tracking: the industry Last helped create drew more than $12B from equity investors in 2020, up eightfold since 2016, while analysts have long argued Silicon Valley runs on a unique, self-perpetuating culture that Fairchild itself seeded. An obituary at this moment is less a eulogy than an audit of how durable that inheritance is.
First-order effects
- Historians and archivists of the semiconductor era lose one of the last primary witnesses to the Shockley split and Fairchild's founding — firsthand accounts of the Traitorous Eight now depend entirely on recorded interviews like those cited in the Times obituary.
Second-order effects
- Each passing of a Fairchild-era founder (Moore, Campbell, now Last) triggers a fresh round of corporate and press retrospectives on the Fairchild lineage, which tends to re-center Fairchild Semiconductor — not later giants — as the Valley's common ancestor in public memory.
Third-order effects
- If the pattern holds, Silicon Valley's founding story completes its shift from living memory to curated history: institutional knowledge migrates from founders' recollections to archives, museums, and written records, changing how the next generation of chip entrepreneurs — backed by record equity flows — understands the culture they inherit.
The trend: The deaths of the Fairchild and Shockley generation are closing out living memory of Silicon Valley's founding, turning its origin myth into documented history even as the startup economy it created hits new funding highs.
