Blue & White Day was founded by beloved Physical Education teacher Kim Bedesem; when Bedesem died in 1993, it was decided that each subsequent Blue & White Day be dedicated to her. Each year, the Blue & White Day T-shirts distributed to students and faculty have the name "KIM" hidden somewhere in the design. While Bedesem created Blue & White Day in its present form in the 80s, similar events existed at Miss Fine's and PCD as much as 60 years earlier. James Howard Murch, PCD's first Headmaster, was remembered by his successor for "the pleasurable relish with which he took to interpret the decimal-splitting rivalries of the Blues and Whites." Miss Fine's School (whose school colors were voted Blue and Grey by the Class of 1918) had "similar challenges" in which Blues and Greys competed.
