History

Porter Wright traces its roots to 1846, when founding father Richard Harrison set up shop at a small desk in the London, Ohio courthouse. A Cincinnati Law School graduate, he grew his practice by riding from town to town to provide legal services to people in need throughout central Ohio. In 1861, at the start of the Civil War, Richard Harrison became a member of the Ohio Senate and wrote its resolution of support of the State of Ohio and the maintenance of the Union. In 1873, after serving in Congress, Harrison started a practice in Columbus with Judge Joseph Olds and Samuel Franklin Marsh. In 1889, William Olin Henderson, a Yale Law College graduate, joined the firm, changing its name to Harrison, Olds and Henderson. In 1914, the firm's name changed to Henderson & Burr, to include attorney Karl Burr.
