Donald Redfield Griffin (August 3, 1915 - November 7, 2003) was an American professor of zoology at various universities who did seminal research in animal behavior, animal navigation, acoustic orientation and sensory biophysics. In 1938 he began studying the navigational method of bats, which he named echolocation in 1944. In Question of Animal Awareness, he argued that animals have conscious minds like those of humans.
