Emfinger's father brought the family to Aldrich in 1942 so he could work in the mines there. When the mines were depleted later that year, the company sold the houses to the miners. Henry soon began documenting his adopted home town with his first camera.
Emfinger founded the Aldrich Coal Mine Museum in the mine's old company store to house his collection of historical artifacts and photographs. He and his wife, Rose, rent out the adjacent Farrington Hall for events and receptions.
Emfinger has also written histories of Aldrich, the Montevallo area, and the Aldrich First Baptist Church.
