Samuel Wilson was a businessman (meat packer) from Troy, New York who was known by his friends, family, and coworkers as "Uncle Sam." During the War of 1812, Uncle Sam (Samuel Wilson) supplied beef to the U.S. army. On his barrels were stamped the letters "U.S." to indicate that it was United States government property. Then, accordingly, a resolution was passed by the U.S. Congress in 1961 to recognize and link Samuel Wilson, the businessman, to the U.S. symbol of Uncle Sam.

However, even before Wilson was selling beef to U.S. government, in the original song "Yankee Doodle", the lyrics in 1775 included the name Uncle Sam. Individuals truly enjoyed singing this song "Yankee Doodle" during the American Revolutionary War.

There was no actual person or depiction of anyone called Uncle Sam in 1775.

Today, everywhere in America, Uncle Sam is one of the most familiar icons and represents a manifestation of patriotic emotion.
