Alexander Kaiser (February 26, 1819 - October 25, 1872) was an Austrian lithographer and painter. Born in Graz, Austria, Kaiser was the second son of Joseph Franz Kaiser, a bookbinder who owned a lithographic firm in Graz. Kaiser is said to have received his first training in lithography from his father before attending the Vienna Academy of Fine Arts. After graduation he became a lithographer that worked primarily in city views, with his views of Brno, Innsbruck, Linz, and Salzburg being recognized as particularly important. He died in Graz, Austria.
