James Victor "Jimmy" Scott (July 17, 1925 – June 12, 2014), also known as "Little" Jimmy Scott, was an American jazz vocalist famous for his unusually high contralto voice, which was due to Kallmann's syndrome, a very rare genetic condition. The condition stunted his growth at four feet eleven inches until, at the age of 37, he grew another 8 inches to the height of five feet seven inches. The condition prevented him from reaching puberty, leaving him with a high, undeveloped voice.
