The Pioneer Celebration was held on campus Friday, May 20, 2011.
Alumni are considered pioneers on or after the fiftieth anniversary of their IUP graduation.
Any of those alumni who have not yet been inducted into the Pioneer Society—which includes awarding of a bronze medallion and lapel pin—are invited to campus to receive those honors during the Pioneer Celebration Luncheon.
As part of the celebration, pioneer classes are invited back for reunions in five-year increments. This year’s celebration welcomed the classes of 1931, 1936, 1941, 1946, 1951, and 1956.
In addition to the luncheon in Sutton Hall’s Blue Room, pioneers attending Friday’s event were invited to tour Sutton Hall and the campus.
The induction ceremony for pioneer classes takes place the day of Spring Commencement. Members of the Class of 1961 were inducted into the Pioneer Society on Saturday, May 7, and took part in the Commencement ceremony that day. See photos from the Commencement ceremony.
