The first Clayton High School classes met in the upper floors of the Forsyth School beginning in 1908. In 1911, the school graduated its first class. Designed by William B. Ittner, the first Clayton High School building opened in September 1917 at 7500 Maryland Avenue. The building, which cost slightly less than $111,000 to construct and $14,000 to partially equip, included six main classrooms and a large study hall-library. The building also featured a chemistry, biology and physics laboratories, an art room, a music room, and several vocational and technical classrooms. The school also included a combined gymnasium and 700-seat auditorium. By the 1940s, however, the building was overcrowded, and the district considered multiple options for its replacement. Although planned to open in 1948, postwar supply shortages delayed the construction of a new building until the early 1950s. In 1952, the school building was sold to the department store chainFamous-Barr, and the school was demolished for the store parking lot. The new building opened in 1954 at 1 Mark Twain Circle, and the first class graduated in 1955. At the start of the schools 1954 opening, the school's entrance featured a six-foot diameter granite globe sculpture weighing nearly ten tons. A block of ice was used to set the globe in place.
