Influential psychiatrist Dr. Robert Spitzer passed away on Christmas Day at the age of 83 from complications with heart disease. Dr. Spitzer is perhaps best known for brokering the 1973 agreement that led the American Psychiatric Association to remove homosexuality as an illness from the Diagnostic and Statistical Manual of Mental Disorder (DSM). He also later helmed the DSM, pushing for uniform standards throughout the profession. He is survived by his wife, three children, and four grandchildren.
