Pieter Zeeman (1865—1943) was a Dutch physicist, who taught at the University of Amsterdam (1900—35) and since 1908 served as director of its Physical Institute. Based on suggestions of Hendrik A. Lorentz, Zeeman discovered in 1896 the Zeeman effect, the resolution of single spectral lines into several components in a magnetic field. In 1902 he was awarded jointly with Lorentz the Nobel prize for physics.
Paul Ehrenfest (1880-1933) was an Austrian physicist, who succeeded Hendrik Lorentz as professor of theoretical physics at the University of Leiden in 1912. He remained there until his death in 1933.
