When the previous mayor, Nehemiah Ford, refused to stand for a second term, Milton Davis moved that the alderman choose Kerr as mayor. Kerr himself seconded the motion.
The council vote resulted in a tie, so Andrew Miller, the councillor listed highest on the assessment rates, cast the deciding vote in favour of Kerr. Kerr also served on the Board of Trustees for Common Schools in 1855 and 1858.
He was Methodist. Kerr died on May 20, 1861.
