The following information was submitted by Stephanie Frederick, a descendent of the artist:
Amos was born on February 2, 1840 and died January 7, 1913. He started out working full-time as a barber and used portrait painting only as a supplemental income until he could afford to pursue it as his sole career. A great deal of Amos' subjects were actually post-mortem, as he was hired by loved ones to immortalize them with the brush. I had always been told that Amos did achieve a nominal amount of fame for his talents, but I have a difficult time finding any mention of him anywhere outside the city of Reading, Pennsylvania (his home town).
