The cichlid fishes of the genus Labeotropheus were first described in 1927, when the type species, L. fuelleborni, was described as a new species by the German ichthyologist Ernst Ahl. A second species, L. trewavasae, was described in 1956 by the British zoologist Geoffrey Fryer.
The Celestial Globe (H57842/29193) was donated to the Milwaukee Public Museum in 1903 along with its companion terrestrial globe (H59492) and a manual of cosmic and terrestrial observations (H57843). The globe was developed by Johann Oelrich Kroehnke (1810-1897), an immigrant to New Holstein, Wisconsin in 1847. Kroehnke was a merchant, farmer and community leader and was intensely interested in intellectual pursuits and education, often at the expense of his personal fortune.
