In 1843 Abraham Lincoln and Stephen T. Logan relocated their law office to the third floor of a recently constructed Greek Revival brick building on the corner of Sixth and Adams Streets. The building, partly visible in this contemporary photograph, was owned by Springfield merchant Seth M. Tinsley. Lincoln and Logan dissolved their partnership the following year, and Lincoln, retaining the office, brought in William H. Herndon as his new partner. With a federal courtroom and post office in the same building, and the county courthouse one block away, the location was ideal.
