He was a writer of both scientific and popular books on birds and served as editor of the avicultural periodical Gefiederte Welt. In 1940 he replaced Gunther Niethammer, who had moved to Vienna, as head of the ornithological department at the Alexander Koenig Museum in Bonn. After Niethammer's return after the Second World War, Steinbacher moved to the Senckenberg Museum where he became curator in 1954.
