Isaac H. Williamson was born in Elizabeth, New Jersey on September 27, 1767. His early education was attained in the common schools of his native state. He later studied law, and was admitted to the bar in 1791. Williamson established a successful legal career, serving as the Morris County deputy attorney, where he earned a reputation for his legal expertise. He first entered politics as a member of the New Jersey House of Representatives, a position he held from 1815 to 1817. After Governor Mahlon Dickerson resigned from office on February 1, 1817, the legislature elected Williamson the new governor. He went on to win reelection annually until 1829. During his tenure, the chancery court was improved; and the construction proposal for the Delaware and Raritan canal was strongly promoted. After completing his term, Williamson served as mayor of Elizabethtown from 1830 to 1833. He also was a member of the New Jersey State Senate from 1831 to 1833; and served as president of the 1844 State Constitutional Convention. Governor Isaac H. Williamson passed away on July 10, 1844 in Elizabeth.
