His fans include Al Gore, Norman Lear and singer Bjork who credited Shlain 's Alphabet vs. The Goddess with inspiring her in her single "Wanderlust" and the album Volta.Dr. Shlain was a surgeon for 38 years at California Pacific Medical Center where he headed the Laparoscopic Surgery Department and an Associate Clinical Professor of Medicine at UCSF.

His ability to synthesize not only information but also genuine wisdom across multiple and disparate disciplines was extraordinary. His talent for communicating to the rest of us what he had discovered was a rare gift"Shlain died in May 2009 at the age of 71 after a battle with brain cancer.

He was the archetypal genius. A painter. A scientist. An inventor. An engineer. Even today, he remains the dictionary definition of a Renaissance man: Leonardo da Vinci. In Leonardo's Brain, surgeon and best-selling author Leonard Shlain undertakes a hypothetical dissection of the ancient master's intellect, attributing the roots of his creativity to a particular arrangement of his gray and white matter...Shlain applies modern neuroscience to probe one of history's most innovative brains and uses da Vinci as a lens through which to view the broader issues of brain organization, creativity, and consciousness... The work stands as the last in a line of probing and entertaining books from a thinker who possessed his own brand of genius. The Scientist Shlain succeeds in keeping Leonardo's Brain accessible and enjoyable. It is intellectual while remaining conversational and is certainly unlike the many, many other books written about da Vinci. Civil Engineering Leonardo's 500-year-old story continues to compel because, as Shlain writes, 'No other individual in the known history of the human species attained such distinction both in science and art as the hyper-curious, undereducated, illegitimate country boy from Vinci.' RappNews.com The importance of Shlains's end of life research offers us hopeful foundations that we can build upon in the areas when neurology and psychology meet. Now, not only are we able to study the effects of a stroke with a clearer idea of how to counteract the damage, we understand the differences in basic personality types.
