As pointed out by P. Laurentius Koch, "Die Brüder Hölzl, Maler aus Dietramszell", in Beitrage zur Heimatforschung, 1991, p.95), the artist was the most successful portrait painter in Ingolstadt in the 18th century. See for his artistic output E. Braun, who wrote the catalogue to the exhibition on Hölzl's work in 1985 in the Diözesanmuseum, Eichstätt. Ingolstadt housed the university of Bavaria, which later moved to Landshut and subsequently to Munich. Hölzl's style reflects the influence of Anton Raphael Mengs.
