“The highest badge of honor a person can wear is honesty. Be truthful at all times.”

Countless children in the 1930s, ‘40s and ‘50s were familiar with these words -- the first of Hopalong Cassidy’s Creed for American Boys and Girls.

An idol to children everywhere, William Boyd portrayed the Western hero “Hoppy,” known as the “epitome of gallantry and fair play.” As noted on his official website (, Hoppy “battles crime and upholds justice with his quick-draw shooting, clear thinking, fists of steel and steadfast character.” Some of Boyd’s papers have been digitized and are one of the most popular collections at the University of Wyoming American Heritage Center.
