Kurd von Mosengeil
Encyclopedia
Kurd Friedrich Rudolf von Mosengeil, also Curd Friedrich Rudolf von Mosengeil (* 7 March 1884 in Bonn; † 5 September 1906 at Wildgall in Rieserfernergruppe), was a German
physicist
.
Kurd von Mosengeil was a student of Max Planck
. In 1905 the latter defended as the first one the theory of special relativity
of Albert Einstein
. In the subsequent years Planck published several works, in which he explained further conclusions of Einstein's theory. He convinced his assistant Max von Laue
and his student Kurd of Mosengeil, as being the first physicists to habilitate as well as to graduate in relativity related subjects.
Through a tragic accident-death of von Mosengeil during a mountain-tour in Tyrol
in September 1906 he couldn't continue his researches. Planck and Wilhelm Wien
shortened the dissertation von Mosengeil's and published it in the Annalen der Physik
in 1907. The paper (Theorie der stationären Strahlung in einem gleichförmig bewegten Hohlraum, en:Theory of stationary radiation in a uniformly moving cavity) contains some relations of thermodynamics
and the mass-energy equivalence
and was partly related to the work of Friedrich Hasenöhrl
(1904). He vouched personally for its content and believed in the permanent value of von Mosengeil's examinations. In fact, the dissertation was groundbreaking for further researches which were used by Planck (1907) and Einstein (1908).

Mass-energy equivalence
In physics, mass–energy equivalence is the concept that the mass of a body is a measure of its energy content. In this concept, mass is a property of all energy, and energy is a property of all mass, and the two properties are connected by a constant...
