Already in 1932 he became a voluntary collaborator of the Mineralogical - Petrographical Department of the Natural History
Museum. In 1934 he became a candidate for assistant, and in 1936 he was made provisional scientific assistant. Then followed
his military service. After the war, in 1948, he was promoted to curator of the first order and was given the duty of heading
the Mineralogical-Petrographical Department. In 1953, he became Director of the Department.
He was greatly hindered in undertaking his scientific work by the ravages of the times and his poor state of health. His main concerns were the occurrence of gold and other minerals in the area of the Hohe Tauern. He developed a lively activity within the Austrian Mineralogical Society of which he was the President for many years. Schiener died in Vienna on 23 August 1962.
