The observance that Henry Welles and General John B. Murray organized in Waterloo on May 5, 1866 was not a spontaneous gesture. Welles had proposed the idea the previous year, arguing that the community should set aside a day to honor the soldiers from Waterloo who had died in the Civil War. Murray helped coordinate the village-wide participation: every business closed, every flag flew at half-staff, every grave at the local cemetery received flowers. The ceremony preceded the national holiday by two years. The National Memorial Day Museum on East Main Street documents the 1866 observance through period artifacts, photographs, and the legislative history that led to congressional recognition, when President Johnson signed a proclamation formally naming Waterloo the holiday's birthplace. The museum sits within walking distance of the M'Clintock House. Two American origin stories on one main street.
