Dr. Barlet is the father of United States President Josiah Bartlet. He was the headmaster of an unnamed preparatory school in New Hampshire that his son attended. His one-time secretary Delores Landingham later served in the same capacity for his son.
He had a complicated relationship with his son and was known to strike or hit him in arguments. It is unknown when he died. According to the "spirit" of Mrs. Landingham speaking to Jed in the Oval Office, the doctor "was a prick who could never get over the fact that he wasn't as smart as his brothers."
