Charles Donald Jacob

Charles Donald Jacob (June 1, 1838 – December 25, 1898) was an American politician who served four terms as mayor of Louisville, Kentucky, two consecutively in 1873–78, then later in 1882–84 and 1888–90. He also served as the U.S. minister to Colombia in 1885–1886. He was a member of the Democratic Party.

In Mayor Jacob's third term, he oversaw the opening of the Southern Exposition. Perhaps Jacob's most lasting contribution was his fourth-term establishment in 1889 of a large park in Louisville, today called Iroquois Park, which was landscaped by Frederick Law Olmsted.
