"A brilliant scholar with a remarkable memory for details, Bill Dayton, as his friends called him, was an encyclopedia of knowledge about plants. He had an excellent command of words and languages, particularly of classical Greek and Latin. This bibliophile assembled a valuable personal library on plant sciences which he so generously shared with others."
