Where was the creator of the The Tolman surface brightness test a professor at?
Tolman surface brightness test: The Tolman surface brightness test is one out of a half-dozen cosmological tests that was conceived in the 1930s to check the viability of and compare new cosmological models. Tolman's test compares the surface brightness of galaxies as a function of their redshift (measured as "z"). Tolman surface brightness test:  Such a comparison was first proposed in 1930 by Richard C. Tolman as a test of whether the universe is expanding or static. Richard C. Tolman:  He was a professor of physical chemistry and mathematical physics at the California Institute of Technology (Caltech).
