In page Mattoon, Illinois:

"

In 1861, the town was officially named after William B. Mattoon, the chief construction engineer working for the Terre Haute and Alton Railroad and partner of the Massachusetts firm "Phelps, Mattoon, and Barnes." The reason for the honor is unclear; some say he won the naming rights because his rail crew arrived first. Others say he beat other claimants in a card game, or that Pegtown residents hoped the wealthy Mattoon would invest in the town if they named it after him. With its combination of excellent transportation and remarkably fertile prairie soils, Mattoon expanded rapidly. By the dawn of the 20th century, Mattoon's growing population and rail access brought manufacturing and industry.
