Erwin Madelung (18 May 1881 –
1 August 1972) was a German physicist. He was born in 1881 in Bonn. His father
was the surgeon Otto Wilhelm Madelung. He earned a doctorate in 1905 from the
University of Göttingen, specializing in crystal structure, and eventually
became a professor. It was during this time he developed the Madelung constant,
which characterizes the net electrostatic effects of all ions in a crystal
lattice, and is used to determine the energy of one ion.
In 1921 he succeeded Max Born
as the Chair of Theoretical Physics at the Goethe University Frankfurt, which
he held until his retirement in 1949. He specialized in atomic physics and
quantum mechanics, and it was during this time he developed the Madelung
equations, an alternative form of the Schrödinger equation.[1]
He is also known for the
Madelung rule, which states that atomic orbitals are filled in order of
increasing n + l quantum numbers
