Edit: OK, I found it.  His name is Arthur D. Carr (1885-1966).  He was the QB on the Ohio team in '03 and '04.  He graduated in '05.  He as an Athens native and graduated from Athens High School in 1902.  I have a copy of the team photo in a book that I could scan and place here, but the quality won't be too great. 

 

You can see Arthur Carr in the back row.  According to "A Significant Presence: A Pictorial Glimpse of the Black Experience in Athens County, Ohio," by Ada Woodson Adams & Nancy E. Aiken, Carr was an Athens native and his family once owned part of the property where Peden Stadium is now located.  This same source says that he was the QB in '03 and '04 and that after graduating from Ohio in 1905 Carr attended Howard University Medical School and graduated in 1912.  He was then reported to have been a medical professor at Howard for about 45 years and a prominent black physician in the Washington, D.C., area.

Thanks for the story; and yes, I think it quite plausible that that experience was a key influence on Rickey's decision to play Jackie Robinson.  Of course, the fact that Rickey had a strong religious belief in the equality of the races is probably why he was agreeable to be Follis roommate in the first place.  (BTW, my wife's sixth grade teacher was Branch Rickey's niece.)  Those kinds of personal interactions are what it often takes to break down racial prejudice.  In the Late Rebellion it was not uncommon for soldiers to have ephiphanies.  One of the most dramatic being by General Benjamin Butler who after viewing a battlefield strewn with black bodies dedicated the rest of his life to black equality not only in the military but in civil society after the war as member of Congress.
