The chronology at Prokudin-Gorsky.org （页面存档备份，存于互联网档案馆） (accessed 26 September 2012) reports six weeks of study with Miethe in 1902. Other accounts give the year as 1889, but a primary source for that extremely early date is not apparent and it does not accord with the circa 1889 biographical details of either man. The major English-language source reporting 1889 (Adamson and Zinkham, p. 108) describes Miethe as "A brilliant young professor at the Charlottenburg Technische Hochschule..." and states (footnote, same page) that "While in Berlin, Prokudin-Gorskii is said to have given technical courses in photochemistry and spectrum analysis at the Technische Hochschule...", which evidences confusion of the facts somewhere along the line: biographies of Miethe all agree that he, not Prokudin-Gorsky, was the professor of photochemistry and spectroanalysis at the Königlich Technischen Hochschule (Royal Technical University) in Berlin, a post he accepted by invitation in 1899 after the sudden death (17 December 1898) of its previous longtime occupant, Hermann Wilhelm Vogel, the discoverer of dye sensitization and himself a color photography experimenter. It was apparently Miethe's first teaching position and the beginning of his involvement with color photography. Until then he had been employed by optical firms such as Voigtländer but was already a notable author, journal editor and inventor in the field of (black-and-white) photography.
