A Bethlehem, Pa. minister and amateur geologist, Steinhauer's 165 page notebook of information and observations on fossils, particularly those found in coal measures is not dated, but tentatively ascribed to the period following his publication in the American Philsophical Society's Transactions, 1817 and before his death. The Academy's 1835 catalogue of the library describes this item as: "Steinhaur, MS. Geological Notes of the late Rev. Henry Steinhaur."
