This is home to our College of Science and Engineering, and its departments of Chemistry and Biochemistry, Computer Science, Geosciences, Mathematics, and Physics and Astronomy.
The building honors Robert A. Thornton, the first dean of SF State's School of Science, and the University's first African American dean. A theoretical physicist, Thornton worked with Albert Einstein before joining the SF State faculty in 1956.
Our observatory, located on the roof, is open Monday and Wednesday evenings. The Charles Hagar Planetarium is on the fourth floor.
