Taft Stettinius & Hollister, commonly known as "Taft", is a major law firm based in Cincinnati, Ohio. It has offices in Cleveland, Columbus and Dayton, Ohio; Chicago, Illinois; Indianapolis, Indiana; Covington, Kentucky; Ann Arbor, Michigan; and Phoenix, Arizona. Taft traces its roots back to 1885, when Worthington & Strong was founded by Judge William Worthington and Edward W. Strong. John L. Stettinius and John B. Hollister joined the firm after its founding, at which point the firm became known as Worthington, Strong, Stettinius & Hollister. In January 1923, Judge Worthington died. In the following year, a young firm headed by Robert A. Taft and Charles P. Taft II, sons of former President William Howard Taft, joined the older firm to become Taft Stettinius & Hollister LLP. The firms labor department, led by J. Mack Swigert, was instrumental in helping Senator Robert Taft draft and pass the groundbreaking Taft-Hartley Act in 1947.
