Robert David Hall

Hall attended Tustin High School in California and went on to graduate from UCLA in 1971 with a degree in English literature. Hall is a former professional musician and accomplished guitarist, and is also proficient on piano, percussion and mandolin. For several years he was a high-profile radio DJ in Los Angeles. His musical talent has been alluded to in CSI: Crime Scene Investigation several times, as his character Dr. Al Robbins would sometimes sing while performing the autopsy or with Gil Grissom when the latter came to the morgue to collect evidence. He has also done extensive voice work on television commercials and cartoons.

In 1978, Hall was critically injured after being involved in a car crash. An 18-wheeler truck struck and crushed his car. The crash also caused the gasoline tank of the car to explode, causing burns over 65% of his body. He almost died in the crash; both of his legs were amputated afterwards. Hall now comfortably uses prosthetic limbs, allowing for personal mobility. Several of his characters, including his CSI character, have openly shared this disability. Hall (as Dr. Robbins) mentioned once that he has prosthetic legs, but never alluded to the accident in reality. He is a prominent advocate for disabled Americans.In addition to starring on CSI: Crime Scene Investigation, Hall has appeared in such films as Starship Troopers and The Negotiator and has made guest appearances in a number of TV programs including The West Wing and L.A. Law. He also furnishes the narration on CourtTV's documentary series North Mission Road. Currently, Hall is working on the short thriller "The Roymann Closure in the Netherlands", written by writer/director David Grifhorst and executive producer Jop Douma.

Hall was married to Susan Petroni from 1969 until their divorce in 1974, and Connie Cole from 1979 until their divorce in 1987. His son, Andrew, was born of his second marriage. Hall's third and current marriage is to Judy Sterns in 1999.
