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.
This 2600 pound sandstone contains 500 million year old animal tracks . The fossil, donated by Eden Stone Company , is from Marathon County, Wisconsin and dates to the middle to late Cambrian period. The rock surface contains ripple marks and a fossil track named Diplichnites. The footprints were produced by a euthycarcinoid—an extinct, primitive arthropod.
