Upham and Francis Bellamy of the magazine's staff. In 1939, after a study of the controversy, the United States Flag Association decided that authorship be credited to Bellamy.

Moss, an authority on the flag and its history, was first given national publicity through the official program of the National Public School Celebration of Columbus Day in October 1892. The Pledge had been published in the Youth's Companion for September 8, 1892, and at the same time sent out in leaflet form throughout the country. During the Celebration it was repeated by more than 12,000,000 public school pupils in every state in the Union.
