Ottokar Tumlirz

He received his education at the University of Prague, obtaining his doctorate with a thesis on the expansion of sound and light waves (1879).

At Prague he worked as an assistant to Ernst Mach (1838–1916) in the institute of experimental physics.

After serving as a lecturer for several years in Prague, he relocated to the University of Vienna in 1890 as an assistant to Joseph Stefan (1835–1893).

He was the author of well-regarded books on the electromagnetic theory of light and electric potential.

In 1908 Tumlirz described careful and effective experiments which demonstrated the effect of the rotation of the Earth on the outflow of water through a central aperture, in a paper entitled "New physical evidence on the axis of rotation of the earth".
