A great little autobiography. Traces the life and times of a conchologist who knew what he wanted to be from the time his elementary-school teacher brought in some shells she picked up on vacation in Florida. From there the author paddled upstream through years of science courses, very competitive university work, his doctoral thesis, and a variety of teaching and research jobs, with a lot of amazing-sounding trips to beaches all over the world to collect shells and study their living architects. What makes it more than just the story of a guy who's way, way too focused on snails is that he was blind from a very early age and had to have someone read every textbook to him, among other hassles.
