The Steppingstone Museum is a non-profit educational and cultural institution on the Susquehanna River, northwest of Havre de Grace, Maryland, whose mission is to preserve and interpret the rural heritage of Harford County, Maryland. The museum displays and preserves the private collection of 7,000 tools and artifacts amassed by J. Edmund Bull along with later accessions. The Bull collection was first displayed at his home, which he called Steppingstone.
