Jay Last

Jay Last. An American physicist, entrepreneur, and prominent art collector, he was a pivotal figure in the dawn of the Silicon Valley technology industry. As a member of the famed Traitorous Eight, he co-founded Fairchild Semiconductor, where his work in photolithography and integrated circuit packaging was fundamental. His later career spanned successful venture capital, archaeological philanthropy, and building one of the world's premier collections of African art.

Early life and education

Born in Butler, Pennsylvania, he displayed an early aptitude for science. He pursued his undergraduate studies in physics at the University of Rochester, graduating with a bachelor's degree. He then earned his PhD in physics from the Massachusetts Institute of Technology, where his research focused on spectroscopy under the guidance of notable professors. His academic work provided a strong foundation in the fundamental principles that would later prove critical in the nascent field of solid-state physics.

Career at Fairchild Semiconductor

In 1956, he joined the pioneering Shockley Semiconductor Laboratory in Palo Alto under William Shockley, but grew dissatisfied with the management. The following year, he became one of the eight key scientists and engineers, the Traitorous Eight, who resigned en masse to form the seminal startup Fairchild Semiconductor, backed by Fairchild Camera and Instrument. At Fairchild Semiconductor, he led the development of critical manufacturing processes, making significant advances in the photolithographic techniques used to pattern silicon wafers. His team's innovations in die separation and packaging were essential for the practical production and commercialization of the first commercially viable planar integrated circuits.

Contributions to Silicon Valley and entrepreneurship

The founding of Fairchild Semiconductor is widely regarded as the catalytic event that established the culture of venture capital-backed high-tech entrepreneurship defining Silicon Valley. After leaving Fairchild Semiconductor in 1961, he co-founded another significant early chip company, Amelco Semiconductor, which later became part of Teledyne Technologies. Along with his Traitorous Eight colleagues Eugene Kleiner and others, he was instrumental in creating the dynamic ecosystem where engineers and scientists could spin off new companies, a model replicated for decades. His success provided both capital and a template for future generations of entrepreneurs in the region.

Later career and legacy

Shifting his focus in the late 1960s, he became a founding partner of the Atlantic Richfield Company's venture capital arm. He also served for many years as a director of Teledyne Technologies. His passion turned toward archaeology and art, leading to major philanthropic support for institutions like the Fowler Museum at the University of California, Los Angeles and the Archaeological Institute of America. With his wife, he assembled an extraordinary collection of African art, particularly from the Kingdom of Benin and the Côte d'Ivoire, which has been exhibited at premier museums including the Metropolitan Museum of Art and the Los Angeles County Museum of Art.

Personal life and death

He was married to Deborah Last, with whom he shared his deep interests in art and archaeology. They were known as generous philanthropists, supporting educational and cultural institutions. He passed away in Los Angeles, California at the age of ninety-two. His life bridged the transformative worlds of microelectronics innovation and profound cultural patronage, leaving a lasting imprint on both Silicon Valley history and the global appreciation of African art.
