In 1955, the Physics Department was moved from East College to the newly completed Olin Science Building, and the space was remodeled into administrative offices. In 1960, the entire building was remodeled, and stair towers were added. It was renamed Trax Hall for Harland A. Trax, Trust ee from 1937 to 1952. The building housed 226 men, with additional rooms on the fifth floor to accommodate visiting athletic teams and other male groups.

The "quadrangle entrance" to the building, which was used in former years, had been where the bay window is located. Stair towers, which had been constructed at both ends of the building, now served as entrances.
