He was first instructed by his father, a wood-carver, and later studied at the Academy, Vienna. In 1846 he went to Rome, where a government stipend enabled him to remain several years. On his return in 1852 he settled in Vienna. His brother Hanns Gasser was also a noted sculptor.
Gasser was professor at the Academy of Fine Arts Vienna from 1865 to 1873; among his most notable students were Viktor Oskar Tilgner and Theodor Khuen. Glasser was awarded a knighthood in 1879. Despite many public commissions, his career was neglected within his own lifetime, with little or no influence on the development of modern sculpture in Austria.
