- Named for Josef Hopmann (December 22, 1890 - October 11, 1975), a German astronomer. His research work was, among other things, in the areas of fixed star parallaxes, star clusters and double stars, as well as profile measurements on the moon. He was director of the Vienna Observatory (1951 - 1962). Asteroid 1985 Hopmann is named in his honor.
- Hopmann was among the long list of IAU-approved farside lunar feature names published in Menzel, 1971.
- Danny Caes notes that Hopmann was labeled Lamarck on Antonín Rükl's 1972 Maps of lunar hemispheres. Lamarck was one of six nearside names that were deemed sufficiently indistinct to merit deleting the nearside names and reusing the names on the farside (IAU Transactions XIVB, 1970). However, subsequent to the October, 1970 printing of provisional ACIC maps illustrating the new IAU farside nomenclature, these six nearside names were reinstated (Menzel, 1971), so Rükl's use of the name Lamarck for the farside feature was incorrect (as he notes in the booklet accompanying his maps). - Jim Mosher
