5803 Ötzi           Discovered 1984 July 21 by A. Mrkos at Klet.
Ötzi, or Iceman, is a popular name for a prehistoric man of the late Stone Age. His mummified body was found on the Similaun Glacier in the Tirolean Ötztal Alps, on the Italian-Austrian border in 1991. The name was proposed by M. Tichy.
