Eddie was mentioned in two issues of the Mar-Ken Journal, although it is not certain from these mentions that he actually attended Mar-Ken.
From the January 24, 1940 Mar-Ken Journal:
SNOOPER: Jo Stern and Eddie Walsh at the Biltmore.
From the October 25, 1940 Mar-Ken Journal:
SNOOPER: Cheering lustily at the Loyola – St. Mary game were Jo Stern and Eddie Walsh. How’d you like the score, Jo?
