Jack Corcoran was well respected in his day and ran the Wrestling and Boxing scene in Toronto much as Frank Tunney would in the years after Corcoran stepped aside. While Corcoran passed the office to Frank and brother John in 1939 he would stay on in the office for a time promoting the boxing side and later in a non-official role.
Frank later said that Jack had been a father figure to him and from all reports Corcoran had the same demeanor Frank would be known for, a sharp contrast to most of the Wrestling-Boxing promoters of the day. There is more on Corcoran on the Frank Tunney page at the MLW site.
