Inventor and manufacturer, born in Rutland.

He received his education in a Vermont primary school, served a four-year blacksmith apprenticeship, and entered the trade in 1825. In 1827 he married Demarius Lamb; by 1836 the couple had four children, with a fifth on the way. Facing bankruptcy, Deere sold his shop to his father-in-law, and departed for Illinois.
