Hermann Traugott Rüdisühli (1864-1944) was born in Lenzburg (Switzerland) in 1864 as one of 14 children of the engraver and painter Jakob Lorenz Rüdisühli (1835-1918). Hermann Traugott Rüdisühli was a disciple of his father first, then he attended Bazel School of Applied Art. In 1883-1887 he studied in Karlsruhe Academy of Arts under Ferdinand Keller and Karl Brünner.  In 1888-1892 he was the head of the painting school in Stuttgart, then in 1892-1898 – in Bazel. In 1898 Hermann moved to Munich, where he achieved much success with his paintings, above all in noble circles.
Hermann Rüdisühli became a reputable sculptor and painter, best known for his landscape paintings. Together with his younger brother, Paul Eduard (1875-1940), he produced more than 4500 such pictures over the years, of which many fell victim to World War II and do not exist anymore. These paintings were in such demand that the brothers reproduced them as postcards. His paintings made Hermann Rüdisühli a very wealthy man, he could for example afford buying Wartensee Castle near Rorschach (Switzerland) as residence.
Despite his tremendous success as an artist, Hermann Rüdisühli's life ended in a sad way, it was tragically broken off in 1944. His death concluded the line of family painters Rüdisühli.
