Jack Arnold Weil (March 28, 1901 – August 13, 2008) was the founder and CEO of the Denver-based Western clothing manufacturer Rockmount Ranch Wear and was believed to be the oldest working CEO in the United States. Weil was well known for coining the phrase "The West is not a place, it is a state of mind." He was the first person to put snaps on Western shirts, patented the saw-tooth pocket design seen on many Western shirts, and is credited with inventing the bolo tie. Weil's wife died in 1990, followed by his son Jack B. in 2008. Weil died at home, surrounded by family, on August 13, 2008.
