The Lincoln-Herndon Law Offices State Historic Site is a historic brick building built in 1841 in the U.S. state of Illinois. It is located at 6th and Adams Streets in Springfield, Illinois. The law office has been restored and is operated by the Illinois Historic Preservation Agency as a state historic site.
The office building is a surviving portion of what was the Tinsley Block, a brick structure built by local developer Seth M. Tinsley in 1840–1841 to provide office space for professionals working in the newly chosen state capital city. The Illinois General Assembly had moved the capital from Vandalia, Illinois to Springfield in late 1839, and local workers had begun to build a new limestone state house, now the Old State Capitol State Historic Site, on the parcel of land just north of the Tinsley Block.
Lawyer Abraham Lincoln and his partner Stephen T. Logan moved their partnership law offices to a third-floor office in the Tinsley Block in 1843. The Illinois Supreme Court, where the partners often pled cases, met in the State Capitol across the street, and the U.S. District Court rented space on the Tinsley Block's second floor.
The firm of Logan & Lincoln broke up in 1844. Lincoln continued to practice law in the Tinsley Block office and accepted a younger lawyer, William H. Herndon, as his junior partner. The firm of Lincoln and Herndon practiced from the Tinsley Block office from 1844 until about 1852.(Wikipedia)
