A perhaps definitive biography of the New Hampshire-born Cass, whose unwavering faith and energy transformed his adopted Michigan from a sodden, by-passed wilderness, away from the main routes of travel and settlement, into a large and important state. Cass, though educated at Phillips Exeter, was stung early with the western fever, and followed his family to Ohio while still in his late teens. There he became a lawyer, was elected in 1806 to the Ohio state legislature, and attracted Jefferson's attention at the time of the Burr conspiracy. Involved in the scattered western frontier battles of the War of 1812, Cass came out of that conflict the appointed civil governor of Michigan Territory, and for the remaining 50 years of his life- save for an interlude of six years as Minister to France- his political life was inseparable from that of Michigan. His biographer is a Detroit newspaper columnist and journalist.
