Wilhelm Lautenbach (* 26 August 1891 in Zwinge; †24 May 1948 in Davos) was a German official at the Economics Ministry at the beginning of the 1920s.
He is known primarily for the so-called Lautenbach Plan, which was discussed at a secret conference on 16 and 17 September 1931 and first rejected but parts of it later implemented by the Papen and Schleicher governments.
He has been called "a pre-Keynes Keynesian".The German economist Wolfgang Stützel who developed the Balances Mechanics (German: Saldenmechanik) appreciates Wilhelm Lautenbach regarding his credit theory of money (Kreditmechanik), calls it "Lautenbachsche Kreditmechanik".
