How did the Syrian Protestant College become the American University of Beirut?

The Syrian Protestant College was chartered in 1863 by the state of New York and began holding classes in 1866. Although it was founded by the American Protestant Mission to Lebanon, the institution was established as an autonomous organization with no official ties to any religious body.1

The college operated under its original name for several decades before officially adopting its present name, the American University of Beirut, in 1920.12
