The Salvation Army Celebrates the True Meaning of National Donut Day Fun foodie holiday is among few with deeper roots News provided by Share this article Share this article ALEXANDRIA, Va., June 1, 2021 /PRNewswire/ -- Many Americans don't know that National Donut Day actually has its roots in doing good. Celebrated on the first Friday in June, this sweet tradition dates back to World War I, when nearly 250 Salvation Army volunteers known as "Donut Lassies" traveled overseas to provide emotional and spiritual support as well as fried confections, supplies, and other services to troops on the front lines. The original donuts were fried in small pans on the front lines, and the Lassies are credited with popularizing the donut in the United States when troops returned home from war. The Salvation Army in Chicago celebrated the first National Donut Day in 1938 to commemorate their work and help those in need during the Great Depression.
