Charles J. Limb might have been a jazz saxophonist. He grew up in a musical family and showed early signs of talent. He idolized John Coltrane and, as a student at Harvard, directed a jazz band. Although he ultimately went to medical school, he chose his specialty (otolaryngology) in part because of his musical interest. As a hearing specialist and surgeon at Johns Hopkins Medical Center, he performs cochlear implants in patients to restore hearing and enable the deaf to appreciate music. His sensibility and passion as an artist continue to inform his research. At least half of his studies during the past 10 years have focused on regions of the brain activated during moments of deep creativity. As he puts it, he wants to understand what went on in Coltrane’s head when he performed brilliant improv on his sax night after night.
