A second circumstance was that Schoenheimer, forced from his position as head of the Institute of Pathology at the University of Freiburg by the policies of the Third Reich, had accepted a position in Clarke’s department in 1933.
While Schoenheimer could formulate problems in metabolism, Rittenberg was perhaps the only individual at that time with the necessary background and training to tackle the difficult experimental details required for biochemical work with 2H.
With considerable foresight Rittenberg and Schoenheimer stated that cholesterol “is formed by the coupling of smaller molecules, possibly those which have been postulated to be intermediates in the fat and carbohydrate metabolism.” In another laboratory, yeast grown in the presence of [2-2H] acetate contained a high 2H level in unidentified sterols.

Rudolph Schadow - Encyclopedia Glossary Meaning Explanation Rudolph Schadow.
Rudolph Schadow (1786-1822), sculptor, was born in Rome, and had his father at Berlin for his first master.
His last composition, commissioned by the king of Prussia, was a colossal group, "Achilles with the Body of Penthesilea"; the model, universally admired for its antique character and the largeness of its style, had not been carried out in marble when in 1822 the artist died in Rome.

Rudolph A. Marcus publishes the first papers describing his theory of electron-transfer reactions.
When de Hevesy's colleague Rudolf Schoenheimer was forced from Germany by the Nazi government in 1933, he fled to Columbia University, where Harold C. Urey had discovered deuterium the year before.
For the remainder of the decade, Schoenheimer worked out methods to introduce first deuterium (which is not radioactive) and later other isotopes at specific locations in fatty acids and amino acids, which he then fed to animals to determine how these molecules are metabolized.

 Harold C. Urey - Wikipedia, the free encyclopedia
At Berkeley, Urey was influenced by the work of physicist Raymond T. Birge and soon joined Niels Bohr in Copenhagen to work on atomic structure at the Institute for Theoretical Physics.
On his return to the US in 1924 he taught at Johns Hopkins University, and then at Columbia where he assembled a team of associates that included Rudolph Schoenheimer, David Rittenberg and T.
During this time, Urey isolated deuterium by repeatedly distilling a sample of liquid hydrogen.

Rudolf Schoenheimer and David Rittenberg first used isotopes as tracers in the study of intermediate metabolism of carbohydrates and lipids.
Rudolf Schoenheimer applied radioactive tracers to the study of the biosynthesis of cell structures and concluded that the body is in a state of dynamic equilibrium.

 Nobel Laureates solve 72 year old, dietary cholesterol puzzle
72 years ago, the first evidence for end-product feedback regulation of a biosynthetic pathway was demonstrated when Rudolph Shoenheimer observed that mice synthesized large amounts of cholesterol when fed a low-cholesterol diet, but this synthesis stopped when the mice were fed cholesterol.
In later years, many details of this cholesterol feedback were worked out, but the main mechanism by which cells in the liver sense cholesterol and thus regulate cholesterol production remained unknown.
Further, this pathway is responsible for the synthesis of cholesterol as well as the feedback suppression of synthesis when cholesterol is taken in from the diet.

He joined the laboratory of Rudolph Schoenheimer, another refugee, who had started to use stable isotopes to trace biochemical pathways.
After Schoenheimer's untimely death in 1941, his students divided the work among themselves and, by chance, Bloch inherited lipids as his research area.
He is survived by Lore to whom he was married for 59 years, a son Peter, a daughter Susan, and two grandchildren.

In 1933, Gluecksohn-Schoenheimer and her husband, the noted physiologist Rudolph Schoenheimer, fled to America.
The first papers on the T-locus mutants make it clear that Gluecksohn-Schoenheimer interpreted these phenotypes as being caused by a genetic defect in the induction of the posterior neural tube by the notochord.
In doing these studies on the T-locus, Gluecksohn- Schoenheimer made a virtue out of necessity and founded the first version of developmental genetics.

As long ago as 1969, Rudolph Arnheim published his 'Visual Thinking' [Arnheim, 1969] in which he argued that humans think in terms of visual images - pictures, symbols, signs - as much as in verbal concepts.
This notion was later further developed by Howard Gardner [1983] with the proposal that we need to recognise a wide range of 'intelligences' as different ways in which humans achieve ordered knowledge.
