From the National Flag Day Foundation:
In Waubeka, Wisconsin, in 1885 Bernard John Cigrand a nineteen year old school teacher in a one room school placed a 10” 38 star flag in an inkwell and had his students write essays on what the flag meant to them. He called June 14th the flag’s birthday. Stony Hill School is now a historical site. From that day on Bernard J. Cigrand dedicated himself to inspire not only his students but also all Americans in the real meaning and majesty of our flag.
This observance, commemorated Congresses adoption of the Stars and Stripes as the flag of the United States on June 14, 1777. This observance was also the beginning of Cigrand’s long years of fervent and devoted effort to bring about national recognition and observance of Flag Day. The crowning achievement of his life came at age fifty when President Wilson, on May 30, 1916, issued a proclamation calling for a nation wide observance of Flag Day. Then in 1949, President Truman signed an Act Of Congress designating the 14th day of June every year as National Flag Day. On June 14th, 2004, the 108th U.S. Congress voted unanimously on H.R. 662 that Flag Day originated in Ozaukee County, Wisconsin.
Happy Flag Day - and remember to display it proudly and properly.
