National American Red Cross Founder’s Day is observed every year on May 21, primarily in the United States. This day commemorates the establishment of the American Red Cross and honors its founder, Clara Barton. The American Red Cross was officially founded on May 21, 1881, in Washington, DC, following Barton's efforts to create a U.S. branch after being inspired by the International Committee of the Red Cross. The organization specializes in emergency assistance and disaster relief, with a workforce that is 90% volunteer-based. Key services include blood donation, disaster services, and support for U.S. Armed Forces members and their families. The day serves to recognize both the organization's mission and Clara Barton's significant contributions to its founding.
