Abner Hazeltine, son of Daniel and Susannah (Jones) Hazeltine, was born on June 10, 1793 in Wardsboro County, Vermont. After graduating from Williams College in Williamstown, Massachusetts, he moved to Jamestown, New York on November 2, 1815 where he founded the Jamestown Academy.
While teaching at the Jamestown Academy, he continued to study law with Jacob Houghton and Samuel A. Brown and began practicing law in Chautauqua County in 1819. Abner Hazeltine wrote editorial pieces for the Jamestown Journal from 1826-1829 and served as a New York State Assemblyman from 1829 to 1830. Hazeltine held office in the twenty-third United States Congress and the twenty-fourth United States Congress from 1833 to 1837.
After serving in the United States Congress, he acted as the District Attorney of Chautauqua County from 1847 to 1850. Hazeltine was denied the right to act as the special judge of Chautauqua County in 1873 because he had exceeded an age restriction of 70 years of age but carried on as the United States Commissioner of the Courts of the Northern District of New York from 1873 until his passing on December 20, 1879.
Abner Hazeltine (1793-1879) is buried in the Hazeltine family plot in the Lake View Cemetery in Jamestown, New York.
