President Lyndon B. Johnson officially recognized Waterloo, New York, as Memorial Day’s birthplace in 1966.
Johnson signed Presidential Proclamation 3727 on May 26, 1966. The proclamation recognized Waterloo’s May 5, 1866, community observance as the first formal, complete, and planned community-wide Memorial Day observance. It gave federal recognition to a claim that had been preserved and promoted locally for decades.
The recognition did not erase evidence of other early post-Civil War commemorations. Communities in several states decorated soldiers’ graves before and after Waterloo’s event, and the national holiday’s development involved many local traditions. Waterloo’s distinction rests on the organized and community-wide character of its ceremony.
This 1966 recognition also predates the Uniform Monday Holiday Act, which later standardized the federal holiday’s Monday observance. The two facts are related to Memorial Day history but concern different issues: origin recognition and calendar scheduling.
