Penn-Ohio Intercollegiate Hockey League

The Pennsylvania-Ohio Intercollegiate Hockey League, sometimes called the Penn-Ohio Intercollegiate Hockey League, Ohio-Penn Intercollegiate Hockey League or Cleveland-Pittsburgh Intercollegiate Hockey League, was a varsity men's collegiate ice hockey conference from 1937-41.

History
The conference existed as early as 1930 as a loose affiliation of varsity and non-varsity programs.

In Pittsburgh, Duquesne University had a desire to align themselves with local schools who had a commitment to varsity intercollegiate hockey. In Cleveland, Al Supthin, owner of the Cleveland Barons was looking to fill the schedule of his newly completed Cleveland Arena. Supthin helped establish the league by offering Cleveland Arena as a home rink for local colleges. The league was officially formed in 1937 and divided into Eastern (Pittsburgh colleges) and Western (Cleveland area colleges) divisions.

The original members were Baldwin Wallace College, Carnegie Institute of Technology, Case Institute of Technology, Duquesne University, Fenn College, John Carroll University, University of Pittsburgh, and Western Reserve College.

Just before the 1939-40 season, Pittsburgh abruptly discontinued their hockey program leaving just two teams in the Eastern division. The league abandoned the two-division format for 1939-40. The other Pittsburgh colleges, Duquesne and Carnegie Tech, dropped hockey after 1940 leaving the league with only the Ohio colleges of Case, Fenn, John Carroll and Western Reserve. The four schools continued competing as a league dropping the "Penn-Ohio" name for the 1940-41 season.

The league ceased to exist after 1941.

''Note: The Case Institute of Technology and Western Reserve University would merge in 1967 to form Case Western Reserve University. However, both institutions would work closely together dating back to the 1890's. The Case Western Reserve Spartans is the present name of the athletic teams at the university.''

After Baldwin Wallace College and the University of Pittsburgh dropped hockey in 1939, the two division structure was abandoned.

Unbeaten Streak
John Carroll's hockey team went undefeated for a record 41 straight games between a January 11, 1939, loss to Duquesne and a March 21, 1941, triple overtime loss to Case in game two of the playoffs. The record is three games better than the modern record of 38 games by Rensselaer Polytechnic Institute in NCAA Division I and St. Norbert College and University of Massachusetts Dartmouth in NCAA Division III.
