FC Libertas Wien
Libertas was founded in 1914 by some high school students. Among them were Josef Gerö, later ÖFB President, UEFA Vice President and Minister of Justice, and Karl Zankl, later WFV President. The rapid-enthusiastic students chose green and white as the colors of their club. The club played  in the lower Viennese leagues for several years. A brief merger in 1922 with the Josefstädter Sportfreunde broke up, until 1928 the club did not get beyond the third class. Nevertheless, the club produced two later internationally very successful players in Josef Horejs and Walter Nausch, who were able to win the Mitropapokal with Sparta Prague and FK Austria Wien.
