Nathan was the son of Samuel Beman and Silence Douglass. He married twice, to Lorane Eliza Smith (1811), and Caroline Bird.
Nathan graduated from Middlebury College, Vermont, in 1807. He then studied theology and preached in Portland, Maine (1810–12), and Mount Zion, Georgia (1812–22).
In 1818, he became president of Franklin College in Athens, Georgia (the founding college of the University of Georgia), though he served only a year in that position. He later served as pastor of the First Presbyterian Church, Troy, New York (1823–63).
In 1824, Beman became a trustee of Middlebury College, his alma mater, a position he held until his death. He was elected president of Middlebury College in 1846, but declined the position.
Beman also served as vice president of Rensselaer Polytechnic Institute in Troy (1842–45), and as its fourth president (1845–65).
