Henry Onderdonk (d. 1895) was president from 1861 to 1864.
He was previously an educator in Baltimore. Under his three-year tenure at the college, only eight students received degrees.
Onderdonk resigned under accusations, never substantiated, that he willingly harbored and entertained Confederate troops under the command of Gen. Bradley T. Johnson, who had encamped on the college grounds.
He opened a private academy in Baltimore after resigning and concluded his education career as headmaster of St. James School in Hagerstown, Md., a position he held until his death.
