Lis Hartel (14 March 1921 – 12 February 2009) was a Danishequestrian athlete. Hartel became the first woman in the equestrian sports to win an Olympic medal when she won silver medals at the 1952 and 1956 Summer Olympics in dressage. She accomplished this feat despite being paralysed below the knees as a result of polio and required assistance on and off her horse. She has had a large impact on horsemanship in Denmark. She also was given a lot of credit for starting the movement for therapeutic riding schools, in fact one in Holland is named the Lis Hartel in honor of her.
