Frank Aretas Haskell was born at Tunbridge, Vermont, the son of Aretas and Ann (Folson) Haskell, on the 13th of July, 1828. Graduating from Dartmouth College with distinguished honors, in the class of 1854, the young man came to Madison in the autumn of that year, and entered the law firm of Orton, Atwood & Orton. His career in this profession was increasingly successful, until in 1861 it was interrupted by the outbreak of the War of Secession.
