B.F. Skinner was an American psychologist, inventor, social scientist, and author. He invented the operant conditioning chamber, innovated his own philosophy of science called radical behaviorism, and founded his own school of experimental research psychology-- the experimental analysis of behavior. His analysis of human behavior culminated in his work Verbal Behavior. He has been cited as the most influential psychologist of the 20th century. 
"He wrote for the school paper but saw himself as an outsider, being an atheist in a religious school, and often criticized the school and its beliefs."
