Great article!
Omitted were colleges out West. Where, Ernie Tanner (1889-1956) integrated the Whitworth College football team (1908-09). Frequently compared to Jim Thorpe, Tanner was professed to be "the greatest athlete ever produced in the state of Washington" in his 1956 obituary. He was a phenomenal four sport/four year athlete in high school, who led tiny Whitworth College to an upset victory over the University of Oregon on the gridiron in 1908 (16-10).
He was also an influential African American labor leader on the Tacoma waterfront for decades. Just picked up the ca. 1905-07 Tacoma track photo with Ernie Tanner below (never thought I'd get an image of him, my favorite pick-up in years).
