He has authored two major books on the history of the Smithsonian Institution and the life of C. D. Walcott (founder of the Smithsonian and discoverer of the famous Middle Cambrian Burgess Shale fossil beds in British Columbia). Dr. Yochelson is the original organizer and prime mover of the North American Paleontological Convention. Anyone and everyone are invited to all three of his special lectures, all of which will be given in Room 517 of the William Browning Building on campus. At the University of Utah in Salt Lake City, I think I'll get sick tommorow and go to the one on Mollusks.
