My Contribution: I was a veteran of the Civil War from 1864-1865, a well-regarded local musician at community and organizational gatherings, and an assessor of the Eighth Ward. I lead the Excelsior Cornet Band.

My Legacy: I synthesized musical talents, political passion, and a spirit of community engagement in order to serve Harrisburg as an agent of change in the North after the Civil War. My work as a community-engaged, politically-active musician served as a precursor to the work of future generations of African American musicians, who used their work to support community change and activism.
