"Reinhold Maier (16 October 1889 – 19 August 1971) was a German politician and the leader of the FDP from 1957–1960. From 1946 to 1952 he was Minister President of Württemberg-Baden and then the 1st Minister President of the new state of Baden-Württemberg until 1953.
He served as the 4th President of the Bundesrat in 1952/53, the only FDP politician in German history to do so to date, as well as one of only two Presidents to not come from either the CDU/CSU or the SPD (the other one is Winfried Kretschmann, who is member of Alliance ´90/The Greens and was the 67th President of the Bundesrat in 2012/13)." - (en.wikipedia.org 31.01.2020)
