Fritz Wintersteller ( 21 October 1927 – 15 September 2018) was an Austrian mountaineer who made the first ascent of Broad Peak together with Hermann Buhl, Kurt Diemberger, and Marcus Schmuck in 1957.
Although never a professional climber, he climbed almost every 4000m-mountain in the Alps, including first ascents of Hochkogel (north face) and Wiesspitze. Three other side summits over 4000m were apparently considered by him to be "not beautiful enough" to climb.
In his later years, he made several trips to Alaska for long ski tours and rafting several rivers. As of 2010 he was living in Salzburg, Austria. Due to difficulties with his hips he spent most of his time bicycling.
