The Purduettes must credit their formation to a brief absence of the Purdue Varsity Glee Club. During World War II, members of the Glee Club were leaving for service so rapidly that the Glee Club schedule had to be curtailed. Al Stewart, the director of PMO, responded by forming an entertainment group of thirteen young women who were chosen and organized as the Purduettes.
Al Stewart originally designed four costumes for the Purduettes including a simple black and white choir gown and the well known white satin off-the-shoulder formal. Al took the women on a tour of the east coast which included a performance at the Eastman Kodak Company in Rochester, New York. The Purduettes were a hit and began entertaining audiences nationwide.
Although Al restored the Men's Glee Club as soon as the war was over, the Purduettes had made their mark in history and the women added a new flare to the Purdue Musical Organizations. Even today, the Purduettes remain the choice group for many audiences.
