Image: Professor Emeritus Roger Thomas, who will be 81 in September, has published in six decades (1965-2019)! When the print version of the Encyclopedia of Animal Cognition and Behavior appears, he will have published in seven decades. Years ago he set two goals after he turned 80, to publish and to solo canoe the Nantahala River one more time, but he said the latter may not happen. Congratulations, Dr. Thomas!
