Question for Sep 14-Gaurav Kane

Identify 'X'

Samuel Wilson (September 13, 1766 - July 31, 1854) was a meat-packer in Troy, New York whose name is purportedly the source of the term 'X'.
At the time of the War of 1812, Samuel Wilson was a prosperous middle-aged meat-packer in Troy. He obtained a contract to supply beef to the Army in its campaign further north, which he shipped in barrels. The barrels, being government property, were branded with the initials "U.S.", but the teamsters and soldiers would joke that the initials referred to "X", who supplied the product. Over time, it is believed, anything marked with the same initials (as much Army property was) also became linked with his name.
