I am fairly certain that the man listed only as
"Fell" who umpired a June 8, 1885 American Association game between St. Louis and Philadelphia was Dr. Alexander Gray Fell of Wilkes-Barre, Pennsylvania (April 20, 1861 - May 1, 1913). There are
dozens of
results on Newspapers.com for "Alex Fell" and "Alexander Fell" of Wilkes-Barre working games in Pennsylvania in 1885, and even one of him referring a football game in 1891. There are
mentions in
early June of 1885 of Alex Fell receiving an offer to work in the American Association for $150 a month, though it appeared he decided the June 8 game was enough for him.
According to his obituary, he went to Princeton and University of Pennsylvania, and gained fame as an athlete at Princeton, setting the intercollegiate 100-yard dash record and played halfback on the football team.
Here are two photos of him, the first from his
Wilkes-Barre Times Leader obit from May 2, 1913 and the second
from Find a Grave.
