Following his studies, he became involved in the Zagreb art scene, especially those circles surrounding the Secession movement.
Croatian painters of that time were distancing themselves from the traditional style of painting and, like their colleagues in Vienna and Munich, brought a new freedom into art.
His work also received a special prize at the exhibition of Croatian painting at the Paris World's Fair in 1906[1] He established his art studio in his own home in Rokovo Perivoj (Roko's Park), which was near the Vila Auer, his parents' villa, where he had grown up.
Following a 70-year hiatus in exhibitions, a retrospective of over one hundred of Auer's works was held at the Klovićevi Dvori Gallery in 2010.
