Hans Queisser

Hans Queisser’s life story is interwoven with the very fabric of Silicon Valley’s birth. From surviving the Dresden air raid as a young boy to working alongside William Shockley, Queisser witnessed the nascent days of the semiconductor revolution. His journey is a testament to the power of scientific curiosity, unwavering determination, and a touch of serendipity.

From Rubble to Research:

Driven by a belief that scientific knowledge held the key to survival, Queisser pursued physics with unwavering passion. He navigated the challenges of post-war Germany, even working under the renowned Nobel Laureate Max von Laue. His thirst for knowledge led him to the University of Kansas, and eventually, to the doorstep of William Shockley, the “father of the transistor.”

Silicon Sunbeams:

Queisser’s work on silicon solar cells at Shockley Labs was groundbreaking, laying the theoretical foundation for future advancements in solar energy. Despite initial rejection, his research with Shockley, now known as the “Shockley-Queisser limit,” has become a cornerstone of the field, inspiring scientists to push the boundaries of solar cell efficiency.

A Front-Row Seat to History:

Queisser was present for Richard Feynman’s iconic “There’s Plenty of Room at the Bottom” lecture, a talk that ignited the imaginations of scientists and engineers, paving the path for the miniaturization revolution. He also witnessed firsthand the birth of the integrated circuit, recognizing its potential even in its rudimentary form.

The Will to Think:

Queisser’s relationship with Shockley was complex. He describes him as a brilliant, demanding, and sometimes stubborn individual, driven by a deep patriotism and an unwavering belief in the power of scientific thinking. He recalls Shockley’s insistence on precision and clarity, his intolerance for vagueness, and his unwavering belief in the potential of silicon.

Silicon Valley’s Moses:

Though Shockley’s own company ultimately faltered, Queisser recognizes his immense contribution to Silicon Valley. He calls him the “Moses of Silicon Valley,” a figure who led the way to the promised land of technological innovation, even if he himself did not reach it.

Inspiring Anecdotes and Quotes:

• “In order to survive, you had to have something that was a skill.” - This belief, forged in the harsh realities of post-war Germany, fueled Queisser’s pursuit of scientific knowledge.
• “There is no law against making small, good junctions.” - Shockley’s unwavering belief in the potential of silicon, despite the challenges, spurred on his team’s research.
• “It sure extracts energy out of people.” - Queisser’s reflection on the demanding nature of Silicon Valley’s early days, where relentless work ethic and innovation were paramount.

Hans Queisser’s story is a reminder that groundbreaking innovation often arises from a potent mix of intellectual curiosity, unwavering dedication, and a willingness to embrace risk. His journey through the early days of Silicon Valley serves as an inspiration for future generations of scientists and engineers who dare to dream big and push the boundaries of what is possible.
