Ulrich, Edward Oscar
ULRICH, EDWARD OSCAR
(b. Cincinnati, Ohio, 1 February 1857; d. Washington, D.C., 22 February 1944)
Ulrich’s career was typical of those nineteenth-century American paleontologists who, beginning as self-taught amateur collectors, reached professional status through initial independent publication, then commissions for state or territorial geologic surveys, and finally, a permanent position with the federal survey, a large museum, or a major university.1
Ulrich was one of eight children of an immigrant Alsation carpenter,2 later a contractor in the Cincinnati area. Ulrich’s formal education was limited to intermittent terms at two Ohio colleges during the 1870’s.3 He resumed carpentry with his father and continued collecting from the extensive and highly fossiliferous Upper Ordovician rocks of Cincinnati. In 1877 the Cincinnati Society of Natural History recognized his abilities with a small-salaried curatorship. He resigned the post in 1879 and spent a lively two years superintending silver mines near Boulder, Colorado.
Relocated at Newport, Kentucky, by 1884 Ulrich had published in the Journal of the Cincinnati Society of Natural History six brief paleontological papers and one major systematic investigation of American Paleozoic bryozoans, to which he expanded the new techniques of thin sections.4
With contracts from the Illinois and Minnesota geologic surveys for further studies of Paleozoic bryozoans, sponges, and mollusks, he combined efforts in 1885 with Charles Schuchert.5 Both men became able lithographic illustrators.
Ulrich made fundamental taxonomic contributions to a dozen major marine invertebrate taxa. Preparation of bryozoan collections for the British Museum (Natural History) and the museum of the University of Munich led to his contributions on the bryozoans and ostracod crustaceans in the first English edition of Karl A. von Zittel’s Text-book of Palaeontology, Charles R. Eastman, trans. (London, 1896). Between 1885 and 1897 Ulrich also described Paleozoic faunas and conducted stratigraphic studies for the Ohio and Kentucky surveys, served five years as curator of geology for the Cincinnati Society, and for nine years was associate editor of the American Geologist.
In 1897 Ulrich’s reputation brought him a temporary appointment to the U.S. Geological Survey. This post, which became permanent in 1901, marked a significant shift in research emphasis from paleontology to stratigraphy. Relocation at Washington, D.C., renewed Ulrich’s association with Schuchert until 1904; they wrote “Paleozoic Seas and Barriers in Eastern North America” during this interval. When Raymond Smith Bassler, who had been Ulrich’s assistant during the previous decade at Newport, joined the U.S. National Museum, they continued close professional ties in major studies of bryozoans (1904).6 Paleozoic ostracods (1923), and the enigmatic conodonts (1926).
In later years Ulrich considered himself first and foremost a stratigrapher and believed stratigraphic syntheses to be his most lasting contributions. Geologic mapping experience in the Upper Mississippi Valley7 and Appalachians culminated in the article “Revision of the Paleozoic System” (1911). Among modifications and proposed additions to the standard geologic time scale were two new lower Paleozoic time-stratigraphic units of systemic rank, the Ozarkian and Canadian, inserted between the restricted Cambrian and Ordovician systems.
In his publications on stratigraphic methods and philosophy, Ulrich wholeheartedly adopted Thomas Chrowder Chamberlin’s concept that records of diastrophic events were the natural and ultimate bases for defining and correlating stratigraphic units. In Ulrich’s view, the differential isostatic adjustments yielded oscillatory littoral displacements, which produced abrupt discontinuities in geologic and faunal sequences deposited in multiple isolated epicontinental basins. These basins were alternately flooded from opposite directions by oceans flanking the North American continent. Rock units and their faunal assemblages bounded by these disconformities were discontinuous both spatially and temporally. Mutually exclusive, they were terminated by nondeposition rather than facies–lateral gradation to coeval units, formed in different depositional enivronments, an alternate concept popularized in the United States by Amadeus William Grabau8 and adopted by Schuchert.
Ulrich’s stratigraphic models were initially of value in interpreting the midcontinent region but failed to explain the more complex Appalachian geology. Ulrich used index or guide-fossil techniques at the most discrete taxonomic levels to make the initial identifications of the datum planes, not to define or correlate tectonic event-based broader stratigraphic units. He considered recognition of the introduction of new generic types a complementary and less than precisely coincident verification of physical boundaries, in contrast to Schuchert’s insistence that the nonrepetitive aspect of organic evolution made fossils fundamental determinants of time and event.
Albertina Zuest, whom Ulrich married in Cincinnati in 1886, died in 1932 after a decade of disabling illness; their union was childless. The following year he married Lydia Sennhauser, his first wife’s nurse during the early stages of her illness. Ulrich was appointed associate in paleontology at the U.S. National Museum in 1914, and occupied that position after his formal retirement from the U.S. Geological Survey in 1932. He continued his studies, accumulating paleontologic evidence for his Ozarkian and Canadian systems, and supplying stratigraphic data for systematic investigations contributed mostly by younger museum associates. These studies failed to provide an acceptable paleontological base9 for Ulrich’s systemic units; the Ozarkian is not part of present usage, which considers the Canadian the basal series of the Ordovician system.
Ulrich was an eminent authority on American lower Paleozoic stratigraphy during the first three decades of the twentieth century. His vast experience and encyclopedic knowledge enabled him to dominate the discipline. Perhaps his most important influence during his years on the U.S. Geological Survey was the controversial aspect of his research and his disputative nature, which caused contemporaries to reexamine critically their own investigations.

2. Edward was the eldest of the five children born to Charles Ulrich and his first wife, Julia Schnell.
3. German Wallace College, now Baldwin-Wallace College, Berea, Ohio, which Ulrich attended in 1874–1875, awarded him the honorary degrees of Master of Arts (1886) and Doctor of Science (1892).
4. Henry Alleyne Nicholson’s work in the previous decade had shown the need for continuing investigations of bryozoans by this method, one that disclosed the usefulness of internal structures in recognizing widespread external homeomorphy.
5. Schuchert later recalled their association in Newport (1881–1888), especially the four years during which he worked as Ulrich’s assistant. See unpublished MS autobiography, ch. 7, p. 30; box XLIII, Charles Schuchert Papers, Manuscripts and Archives Division, Sterling Library, Yale University.
6. Bassler, who prepared the bryozoan section for the 2nd ed. (1913) of the work by Karl A. von Zittel, culminated his systematic work within the Ulrichian framework of ideas in Treatise on Invertebrate Paleontology, Part G. Bryozoa (Lawrence, Kansas, 1953): its excellent organization and bibliography reflect his abilities as a compiler. In Ulrich and Bassler’s investigations, thin sections were studied primarily with the 10-power hand lens. Their contemporaries, Edgar Roscoe Cumings and Jesse James Galloway at the University of Indiana, made initial microscopic studies of bryozoan modes of growth and functional morphology, techniques now being applied to investigations of systematics and phylogeny for the revision volume of the Treatise.
7. The only major unpublished work from this period is the joint geologic mapping and stratigraphic study with Nevin Melancthon Fenneman in 1904–1914 of the Cincinnati East 15-minute quadrangle. The map and accompanying MS formerly in the survey’s Washington open files is no longer extant. The Department of Geology of the University of Cincinnati presently holds a photostatic copy. Ulrich’s adamant positioning of the Richmondian stage as basal Silurian disagreed with the usage of the Geological Names Committee of the U.S. Geological Survey, and most contemporary usage, which held it to be uppermost Ordovician. See William Henry Shideler, “The Ordovician-Silurian Boundary,” in Ohio journal of Science, 16 no.8 (1916), 329–335.
