As a young man, Hirth took up gliding and was soon drawn to the
Wasserkuppe, then the focus of the German gliding movement, earning his pilot's licence in 1920. In 1924, Hirth lost a leg after a
motorcycle accident. From then on, he would fly while wearing a wooden
prosthesis. He had the
fibula from his amputated leg fashioned into a cigarette holder In 1928, he graduated from the Technical
University of Stuttgart with a diploma in engineering and began to focus on aircraft construction. Later in the year, he became the first to correctly identify the phenomenon of
wave lift, the highest form of lift source available to soaring pilots. In Jan. 1934, he joined Professor Georgii's South America expedition, along with
Peter Riedel,
Hanna Reitsch, and
Heini Dittmar, to study thermal conditions, with his sailplane "Moatzagotl". While in Argentina, Wolf set a record of seventy-six successive loops. Wolf Hirth also took part in International Championships of Touring Aircraft
Challenge 1929,
Challenge 1932 (6th place) and
Challenge 1934 (13th place). After some time in the USA he returned to Germany in 1934 because of US economic depression. ==Glider company==
