William "Willie" Julius Champion Jr. (June 15, 1880 – February 12, 1972) was the inventor of Kalah, a game in the Mancala family.
William Julius Champion Jr. was born on June 15, 1880, in Trinidad, Colorado, to US Civil War veteran William Julius Champion Sr. and Elvira Hellen Gammons, a descendant of Mayflower passenger Thomas Rogers.
Champion graduated cum laude from Yale University in the class of 1905 after walking from his childhood home in White Cloud, Michigan, to Yale's campus in New Haven, Connecticut (over 850 miles), and "earning all of his expenses" as he put it.
The jobs he worked to pay for school included a sales agent for the Saturday Evening Post and a summer on the road with the Barnum and Bailey Circus (which later became the Ringling Brothers and Barnum and Bailey Circus).
A local newspaper obituary called him a "radio pioneer", saying that after graduating from Yale, Champion moved to the Boston area and went to work with Lee DeForest, inventor of the vacuum tube, and goes on to say that he "helped set up and operate Boston's first radio transmitters".
