Jimmy Scott

After success in the 1940s and 1950s, Scott's career faltered in the early 1960s. He slid into obscurity before a comeback in the 1990s. His unusual singing voice was due to Kallmann syndrome, a rare genetic disorder that limited his height to 4 feet 11 inches (150 cm) until the age of 37, when he grew by 8 inches (20 cm). The syndrome prevented him from reaching classic puberty and left him with a high voice and unusual timbre.
