History
While platted and settled a few years earlier, "New Jefferson" was organized in the winter of 1855–56 and officially incorporated in January 1872. It began as a farming community and remains so today. The first settlers of the new city were the family of George S. Walton who built there in 1855. During the Civil War, Jefferson as well as Greene County contributed its sons to raising Company H, 10th Iowa Infantry (1861) and Company E, 39th Iowa Infantry (1862). The railway came to Jefferson in the decades after the Civil War. Jefferson's first mayor was Mahlon Head, elected in 1872. Jefferson's library was completed in 1904 through the generosity of the Carnegie library fund. The stretch of Lincoln Highway that runs through Jefferson was completed c. 1924.

Arts and culture
Mahanay Memorial Bell Tower
Completed in October 1966 at nearly 14 stories or 168 feet (51 m) in height, the Mahanay Memorial Bell Tower is named for Floyd Mahanay who left an endowment of $350,000 to have the tower built. However, the funds were not sufficient to provide for a full carillon of bells on top. In 2016, upon the 50th anniversary of the tower being built, $440,905 funds were acquired to add a four-octave, 47-bell carillon at the top of the tower. The bells are expected to be chiming the summer of 2017 and will be operated by a digital piano to give tunes for weddings, birthdays, funerals and even the local high school's fight song after games. For many years, the tower provides the current time with a recording of the Westminster Chimes. An elevator in the tower takes visitors to the observation deck which overlooks five Iowa counties. As of 2016, there were more than seventeen other buildings in Iowa taller than the Mahanay Tower: 12 in Des Moines, 3 in Cedar Rapids, and 2 in Davenport.
Festivals
Since 1980 annually on the second Saturday of June, the Bell Tower Festival has a parade in the morning and a street dance in the evening.
