Henry Gibson also departed after the 1970–71 season. Johnson and he were replaced by former "Hogan's Heroes" stars Richard Dawson and Larry Hovis, both of whom had appeared occasionally in the first season. However, the loss of Johnson's many popular characters caused ratings to drop
Paul S. Martin Paul S. Martin Paul S. Martin (born in Allentown, Pennsylvania, 1928 - died in Tucson, Arizona September 13, 2010) was an American geoscientist at the University of Arizona who developed the theory that the Pleistocene extinction of large mammals worldwide was caused by overhunting by humans. Martin's work bridged the fields of ecology, anthropology, geosciences, and paleontology. In 1953, Martin received his bachelor's degree in zoology from Cornell University. In 1953 and 1956 he completed his master's and doctorate programs at the University of Michigan and then proceeded with postdoctoral research at the Yale University and the University of Montreal.
