Lewis Lund Judd was born in Los Angeles on February 10, 1930. He was the first of two sons of Dr. George Ezra Judd, an obstetrician-gynecologist, and Emmeline (Lund) Judd, a housewife. His younger brother, Howard, also a doctor, died in 2007. In addition to his wife, he is survived by three daughters: Stephanie Judd, psychologist; Catherine Judd, professor of English at the University of Miami; and Allison Fee, occupational therapist – and five grandchildren.

After graduating from Harvard School, a preparatory school for boys in Los Angeles (which is now part of the Harvard-Westlake School co-education), Dr. Judd entered the University of New York. Utah, where he graduated in psychology in 1954. He studied medicine at George Washington. Then at the University of California, Los Angeles, where he graduated from medical school in 1958. He did his internship and residency in psychiatry at UCLA. After serving in the military as a psychiatrist at Griffiss Air Force Base in Rome, New York, he joined U.C.L.A. faculty of psychiatry.

In 1970, Dr. Arnold J. Mandell, founding president of the Department of Psychiatry at the University of California at San Diego, recruited Dr. Judd. Both created the ministry from the ground up, making it a leader in federal funding for research. It was during a consultation on an external program to help teens struggling with drug problems that Dr. Judd met a social worker, Patricia Hoffman, with whom he married .

Dr. Judd became chairman of the department in 1977 and, after three years as head of the MNI, returned to British Columbia. San Diego. He remained there for 36 years and became a recognizable public face in the field of brain sciences. He also maintained a small clinical practice, specializing in the treatment of severe depression.

When he retired as president in 2013, a press officer from a university questioned Dr. Judd about his legacy.

"What I'm most proud of is that psychiatry is increasingly recognized as a true biomedical science," he said. "That was scornful. A broken spirit was not as real as a broken bone. We have practiced physical medicine, but we have dismissed brain biology, which has a huge effect not only on our behavior, but also on our body. "
