Constructed in 1894 as the first structure on the present Tulane University campus, Gibson Hall was designed by architects Harrod and Andry in the Richardsonian neo-Romanesque style and constructed of stone over brick. It was named for Randall Lee Gibson, U.S. Senator from Louisiana and the first President of the University Board of Administrators.
The building houses most of the senior level administration as well as the Office of Undergraduate Admission, Financial Aid Office, Accounts Receivable, the department of Mathematics, and general pool classrooms.
