Caldwell, Zenas, brother of Merritt, was born in Hebron, Oxford county, Me., on the 31st of March, 1800, graduated at Bowdoin College in 1824, and soon after leaving college took charge of the Academy of Hallowell. In 1825 he was licensed as a local preacher, and for most of the time of his connection with the Hallowell Academy he supplied the Methodist congregation in Winthrop. In the same year he was unanimously elected principal of the new Methodist Seminary at Kent's Hill, Readfield, Me., and proved himself abundantly adequate to any service that devolved upon him. But his whole work was to be performed within six months; his lungs became seriously affected, and he died triumphantly on Dec. 26, 1826. In 1855 a small duodecimo volume by the Rev. S. M. Vail, D.D., was published, containing a memoir and several of his productions, in prose and poetry. — Sprague, Annals, 7:699 sq.
