Singer Jimmy Scott died of natural causes Thursday morning at his home in Las Vegas at age 88, according to his booking agent, Jean-Pierre Leduc.

Scott suffered from Kallmann's syndrome, a lifelong affliction that prevented his body from maturing through puberty. The condition slowed his growth, leaving his stature at 4 feet 11 inches until his late 30s. It also affected his vocal cords, giving him a high voice that was often misidentified as a woman's.

Marian McPartland, who gave the world an intimate, insider's perspective on one of the most elusive topics in music — jazz improvisation — died of natural causes Tuesday night at her home in Long Island, N.Y. She was 95.
