Henry Erben
1850

From Bruce Brewer, application for historic organ certification:
"...the instrument is solidly attributed to be the work of Henry Erben, (2) The original point of installation was Saint Mary’s Catholic Church in Rockville MD, and (3) because of the Maryland installation, fabrication occurred in the factory on South Eutaw Street in Baltimore (reference “Henry Erben, Portrait of a Nineteenth Century American Organ Builder, page 11, Erben maintained a factory at No. 7 South Eutaw Street in Baltimore between 1847 and 1863. “with full service facilities as well as a shop for the manufacture of cases and actions; only pipes needed to be sent from New York to complete organs”.

"The casework is Victorian Gothic in style, with two “towers” flanking a center panel which pivots forward near the top to permit access to the organ swell shades. The display pipes in the front of the case are false, being original guilt on Gesso on a wooden-slat base. Each of the two towers. The entire display has a 3-3-9-3-3 configuration, with three pipes, in each of the pedal towers, the center panel is subdivided into three facets configured 3-9-3, each section is contained in a separate arch unit, and all three of these arch units are encompassed by one binding arch assimilating the entire center section into one panel. This pipe display rises above the keyboard section, forming the majority of the upper half of the casework."
