Many of us in the greater turtle conservation and biology community were deeply inspired by him, and he most generously shared of himself and his passion for turtles with all of us. He introduced us to the wonder of turtle diversity and natural history through his seminal 1967 book "Living Turtles of the World", followed by his even more impactful 1979 book, the "Encyclopedia of Turtles" and many other major books and articles over his lifetime. For many of us he was not only a catalyzing inspiration and much-admired role model, but also a trusted mentor and close friend and energetic travel companion to many remote and wild places on Earth, always in enthusiastic and passionate pursuit of fascinating turtles or tortoises. He loved the natural world and the people in it, always celebrating the diversity of turtles and other animal life, as well as the people he met and befriended. He treated everyone as equals and saw in all the potentials of friendship, camaraderie, and collegiality. He was a true Renaissance man with broad interests in humanity, the natural world, and art in its many forms.
