Observation • Documentation • Public Preparedness
The Society dates its formal beginning to 14 November 1878, when six residents of Bethlehem and South Bethlehem met to preserve testimony arising from a sequence of disturbances along the Monocacy drainage. The surviving record does not identify the cause of those events. It does show why the participants believed informal storytelling was no longer an adequate record.
Between 29 October and 11 November 1878, households along a short section of the Monocacy reported repeated nighttime whistles, unexplained movement at fence lines, and displacement of small objects from sheds and yards. Three reports were made independently before the witnesses were known to have compared accounts.
On the night of 9 November, surveyor Isaac Brann and physician Amos Weller were called to a mill property after two employees refused to re-enter a lower service passage. Brann’s notebook records intermittent movement beyond lantern range and a sequence of three spaced whistles from the drainage side. Weller recorded no direct observation and cautioned against assigning an animal identity.
The following morning, schoolteacher Margaret Hollenbach interviewed the mill employees separately. Their statements disagreed on size and distance but agreed on direction of movement, timing, and the whistle sequence. Her insistence that the statements be retained separately became the basis of the Society’s later witness protocol.

Provided measured site plans, distances, drainage alignments, and the first standardized location sketches preserved in the archive.
Insisted that witnesses be interviewed independently and that original wording survive later cataloging. The 1978 Hollenbach Protocol was named for this practice.

Location: rear schoolroom, Second Ward, Bethlehem.
Persons recorded: Weller, Brann, Hollenbach, Elias Kern, Samuel Diehl, and “M. Rausch” (first name uncertain).
Resolved: that accounts of “unclassified night disturbances” be collected without requiring agreement as to cause; that original statements be retained; that locations be drawn where practicable; and that correspondence from neighboring counties be accepted.
The common name “Cock Goblin” does not appear in the surviving founding minutes.
The 1878 members did not claim discovery of a species, possession of a specimen, or proof that all Monocacy reports had one cause. The original constitution describes the subject as a recurring class of local reports requiring preservation.
The modern Council recognizes the 1878 Society as its institutional predecessor because the archive, case-numbering practice, and independent-statement rule passed through each later reorganization.
