History
Johnson County was established in December 1837 by the legislature of the Wisconsin Territory, one of thirteen counties established by that body in a comprehensive act.[4] The county's area was partitioned from Dubuque County, and was not initially provided with a civil government, instead being governed by Cedar County officials. It was originally named for the US Vice President Richard M. Johnson (1780–1850).[5] In 2020, the Johnson County Board of Supervisors voted unanimously to change the county's namesake to be Lulu Merle Johnson (1907–1995), the first black woman in the state to earn a doctorate; Vice President Johnson was a slaveowner who had sexual relations with several of his slaves.[6]
The first courthouse in the county was a two-story log cabin structure, built in 1838 in the settlement of Napoleon,[7] about two miles south of the current courthouse.[8] The building stood across from what later would become the James McCollister Farmstead on land later owned by Philip Clark.
After Iowa City was established by fiat as the new territorial capitol of Iowa, the county seat was removed there.[9] The second Johnson County Courthouse, the first in Iowa City, was built on Lot 8 Block 8 of the County Seat Addition to Iowa City in 1842 for $3,690.[8] This location was in the southeast corner of the intersection of Harrison and Clinton Streets. The building was 56 x 28 feet and two stories tall.[10] It was built by James Trimble, who had previously built the first jail.[8]
A third courthouse was built in 1857 in the courthouse square on Clinton Street between Court and Harrison Streets. It was used until 1901, after cracks appeared in its south wall in 1899.[11] The building was apparently built of brick with stone and wood ornamentation.[12]
