Ethan Gruber, MA
Director of Data Science

Ethan Gruber is the Director of Data Science at the American Numismatic Society. With more than fifteen years of experience in digital humanities and cultural heritage web development projects, Ethan is responsible for developing all of the Society’s digital collections (MANTIS), library, archives (Archer), and research information systems, like Online Coins of the Roman Empire (OCRE) and PELLA. Specializing in Semantic Web technologies, Ethan is on the scientific committee for and chief software developer of, an international collaboration to define the intellectual concepts of numismatics following Linked Open Data methodologies and aggregate numismatic content that makes projects like OCRE and PELLA possible. He is also on the scientific committee and co-PI for the NEH-funded University of Virginia-affiliated project,, a Linked Open Data project for Greek pottery.


The work of Ethan Gruber focuses primarily on Knowledge Engineering, a computer science subdiscipline, modeling complex humanistic knowledge in machine-actionable terms according to network theory. He is interested in applying these principles to both numismatics and Greek pottery, hoping eventually to enable cross-disciplinary research in iconography, in particular, and has begun to experiment with new methods for visualizing relationships between Hellenistic monograms that appear on clusters of coin types.

Some recent work includes “Linked Open Data and Hellenistic Numismatics” and “Linked Open Data Vocabularies and Recognizing Intellectual Contributions via ORCID: The Example of” (forthcoming) authored with Tyler Jo Smith, Abigail Bradford, and Renee Gondek.
