This organ was installed by organ builder Adam Jerscheid (1867-1928), who worked for the Baltimore Branch of Roosevelt (A. Stein manager), in the late 1880s, then worked for Henry Niemann, and this, the first indication of returning to work for Stein, after Stein established his own firm, in Baltimore c1895.
Adam Jershceid was the son of Henry J. Jershceid, also an organ builder, in Baltimore. The document which places Jerscheid at Florence is a notice of his traveling to Florence, in the Baltimore Sun Paper June 11, 1901.
