1867—Bethlehem, Pennsylvania
A photograph of 3 trombonists of the Moravian community shows, from left to right, Charles F. Beckel, Jedidiah Weiss, and Jacob Till, with an empty chair in honor of their deceased colleague, Timothy Weiss. At least one of the instruments pictured is very likely an alto trombone (see below image; public domain) (Moravian Archives, Bethlehem, PA).
