Today, June 1, marks National Donut Day (or, as some might spell, doughnut). According to holidayinsights.com, National Donut Day is always the first Friday in June, and "was established in 1938 by the Chicago Salvation Army to raise much-needed funds during the Great Depression, and to honor the work of World War I Salvation Army volunteers who prepared doughnuts and other foods for thousands of soldiers."
Also from holidayinsights.com, is the following excerpt concerning the history of National Donut Day:
"The original Salvation Army Doughnut was first served by Salvation Army in 1917. During WWI, Salvation Army "lassies" were sent to the front lines of Europe. These brave volunteers made home cooked foods, and provided a morale boost to the troops. Often, the doughnuts were cooked in oil inside the of the metal helmet of an American soldier. The American infantrymen were commonly called doughboys. Salvation Army lassies were the only women outside of military personnel allowed to visit the front lines. Lt. Colonel Helen Purviance is considered the Salvation Army's "first doughnut girl."
