Then: Old Laboratory, 1838, Now: Conservatory of Music, 1964, Minoru Yamasaki
The Old Laboratory, located south of Colonial Hall, was built in 1838 according to plans obtained by Dr. Dascomb when a student at Dartmouth and Yale. It was a one-story brick building, 30 by 50 feet. It contained a laboratory, a lecture room, and a private work-room for Professor Dascomb. Dr. Dascomb continued to use this building for nearly forty years. In 1868 the building was remodeled, the seats were lowered, and the lecture room was used later as a general recitation room. It was torn down in 1883, to provide a site for Sturges Hall.
