Dr. Albert Ellis was sometimes called the Lenny Bruce of psychotherapy: He was funny, profane and controversial. His theories on cognitive therapy, first presented in the mid-1950s, challenged the thinking of Sigmund Freud. By the time he died this week at age 93, Ellis had become considered by many to be as influential as Freud.
His friend and former colleague John Norcross talks to Scott Simon about Ellis' work. Norcross is a clinical psychologist and professor at the University of Scranton.
