1877, Dr. William Kershaw was appointed headmaster. Under his leadership, the Academy gained prominence and expanded its activities with the introduction of the Inter-Academic League (1887), The Belfry Club, one of the oldest high school drama clubs in the country (1894), and The Academy Monthly (1885), one of the oldest student literary magazines still in existence. During his headmastership, GA graduated a future University of Pennsylvania president, a Supreme Court justice, and a primate of the Episcopal Church. 20th century In 1915, Dr. Kershaw retired and Dr. Samuel E. Osbourn was appointed headmaster. Under Dr. Osbourn's leadership, the school increased in size, focused on scholarship and continued to produce some of Philadelphia's finest citizens. Under Osbourn, GA established the eighth oldest Cum Laude Society chapter in the nation and started an endowment. After the World Wars, GA was led by headmaster Donald Miller who was instrumental in the move from Germantown to the current Fort Washington campus. By the 1960s, more and more lower income minority families moved into Germantown and GA families left Germantown for the nearby suburbs. In five years, "The Miracle of Fort Washington" (a term coined by Judge Jerome O'Neill, '28) occurred as the school moved from city to suburb. In this transition, GA coeducated, accepting girls in 1961 with the first co-ed class graduating in 1968. Traditions and symbols The school colors are red, black, and blue. Originally, red, white, and blue, the white was changed to black upon the death of Abraham Lincoln in 1865. Another legend suggests that GA changed its colors so its cricket team would not be confused with the nearby Philadelphia Cricket Club (with red, black, and yellow as club colors) team, as the white would turn to yellow after long and hot matches. GA/PC Day is an annual tradition where GA plays against its rival William Penn Charter School in football, soccer, field hockey, cross country, girls' tennis, water polo, and golf. The football game brings alumni back from both schools and reunions are held the weekend of the games. The competition is the oldest of its kind dating back to 1886. Lower School Field Day is an annual tradition that brings the red and blue teams into fierce competition. The teams are generational for existing GA families and is a staple to the school spring calendar. The Belfry serves as a symbol of the old and new school
