When I first became an entrepreneur the one person whom I especially wanted to work with was Dr. Alejandro Zaffaroni. I was blessed to have some unique experiences working with him that I thought would be worth sharing. As many of you know, Dr. Zaffaroni was involved in fundamental biotech innovations ranging from the birth control pill to the patch to the Affymetrix gene chip. Generally he’d be involved on the technical, business, and people sides. On March 1 2014, at age 91, Dr. Zaffaroni passed away. His inventions of course impact many lives, yet how he worked directly with people was equally compelling. Mario Rosati once mentioned to me that Dr. Zaffaroni was the best he had seen in a board room. I thought I would share a few personal stories from my own interactions with him that have stuck with me over the years.
