(Neuhausen near Stuttgart 1902 – 1974 Villach) met Anton Kolig at the Stuttgart Art Academy and came several times in the 1920s to Carinthia, to the Gail valley, where he lived from 1931. Travels to Italy, where he always returns and exhibits.

Mahringer is one of the best landscape painters within classical modernism in Austria, and with increasing maturity also found more and more connection to contemporary currents in modern art.
His colourful and almost cubist structured paintings and watercolours with motifs from Carinthia and the Dolomites region are among the most sought-after pieces on the Austrian art market.
