Frederick Wayman 'Duke' Slater was a pioneering Black professional football lineman and later a Chicago judge, whose career connects the earliest years of the National Football League to Chicago's civic history. Born December 9, 1898, in Normal, Illinois — not Chicago — Slater starred at the University of Iowa from 1918 to 1921, becoming the school's first Black All-American and playing on Iowa's 1921 national championship team. Turning professional in 1922, he became the first Black lineman in NFL history and, over ten seasons with the Milwaukee Badgers, the Rock Island Independents and the Chicago Cardinals (1926–1931), was the longest-tenured Black player of his era, earning multiple All-Pro selections as a two-way tackle. After football he built a legal career in Chicago, becoming the city's second Black judge. Slater was inducted into the College Football Hall of Fame in 1951 and, nearly seven decades after his playing career, into the Pro Football Hall of Fame as a member of its Centennial Class of 2020. He died August 14, 1966, in Chicago.

Notes
Sports Encyclopedia roster CTL-SPE-0383. Roster note verified: Slater was born in Normal, Illinois, NOT Chicago, so no 'from Chicago' relationship is emitted; his Chicago connection runs through the Chicago Cardinals (not a homed endpoint in this pass) and his later Chicago judgeship. Curator's Judgment (DRAFT): Slater is a cornerstone record for CTL — the first Black lineman in NFL history, a Chicago Cardinal and a Chicago judge — and his late Hall of Fame recognition in the Centennial Class of 2020 is itself a documented case of delayed institutional recognition.
