Review
Roy Clay has written a masterpiece that is captivating from its action-packed introduction to its soul stirring ending. His inspirational words re-count a near century long journey that captures his unlikely rise from humble Midwest beginnings to an American technology pioneer and Silicon Valley entrepreneur. I highly recommend this accurate account of how his unrelenting vision and determination helped pave the way for me and many executives who came behind him. Thanks Roy, for opening doors, and thumbs up for this brilliant memoir that is a must read for all. John W. Thompson, Chairman of the Board, Illumina (former Chairman of the Board, Microsoft)
I first met Roy in 2000 and he instantly embraced the Rainbow PUSH Coalition's campaign for equity, diversity and inclusion in Silicon Valley and the tech industry. He talked to me about his personal experience, where his peers in several companies rose to the highest heights while he was stifled. There was no talent deficit, but an opportunity deficit. But Roy proved as he has all of his life - battling segregation in St. Louis to breaking down walls of exclusion in Silicon Valley - that he would be unstoppable. Roy's exhilarating story is a model for all to keep hope alive and never give up on your fight for dignity and respect. Roy's book is a must read and a guide for all those striving for excellence and equality. Reverend Jesse L. Jackson, President and Founder, Rainbow PUSH Coalition. American civil rights leader and activist
Roy Clay was among the founding fathers of Silicon Valley. Everyone should know his story and now they can through Unstoppable Shellye Archambeau, Fortune 500 board director, Advisor and Author
Unstoppable' is the perfect title for this autobiography. As long as we've known Roy, he's never let anything get in his way or made an excuse for not getting the right things done. He is truly unstoppable; and that one word describes his actions and his heart Caretha Coleman - Chairman of the Board, The Leverage Network, Ken Coleman - Chairman of the Board, EIS

About the author

Roy Clay Sr. was born in Kinloch, Missouri in 1929. After attending segregated public schools, he became one of the first African-Americans to graduate from Saint Louis University (SLU) with a B.S in mathematics in 1951. He relocated to California and began working as a programmer at Lawrence Livermore National Laboratory. His early work involved creating a radiation tracking system to study the aftermath of a nuclear explosion.
Hired by David Packard at Hewlett-Packard (HP) in 1965, Clay became a founding member of the Computer Division, where he was director of the team that developed the HP 2116A, Hewlett-Packard’s first minicomputer. He established Roy L. Clay and Associates and worked closely with Tom Perkins (Kleiner Perkins) to become a contributor to the formation of Silicon Valley as we know it today. Clay founded Rod-L Electronics in 1977 and, as CEO, led it until 2015.
Mr. Clay was the first African American to join the City Council of Palo Alto, California and become Vice Mayor in 1976. He became the first African American member of the Olympic Club of San Francisco in 1989. He was inducted into the Silicon Valley Hall of Fame in 2003. Clay was married to the late Virginia Clay, and has three sons, Roy, Jr, Rodney, and Chris. He is known as the Godfather of Silicon Valley.
