Veblen was an active member of the American Mathematical Society, serving the Society as Vice-President in 1915 and President in 1923-24. He was the Colloquium Lecturer for the Society in 1916 when he gave a series of lectures on topology.

He made important contributions in topology and in projective and differential geometries, including results important in modern physics.
