The Ruckelshaus law firm originated in 1895. John C. Ruckelshaus, grandfather of current senior partner, John C. ("Jack") Ruckelshaus, first started practicing law individually, and later formed an association with Russell Ryan, giving the firm its first name, "Ruckelshaus & Ryan." The firm name and associations continued until the elder Ruckelshaus' son John K. Ruckelshaus, joined the firm, and it was renamed Ruckelshaus & Ruckelshaus.
Later, the firm expanded to include two attorneys from Washington, D.C.-Gerald Reilly, the primary author of the Taft-Hartley Act, and Charles Rhetts both of whom specialized in labor law. When John C. O'Connor joined the firm, the name was changed to Ruckelshaus, Reilly, Rhetts & O'Connor. This association continued until 1957, when George Craig joined the partnership upon completion of his term as Governor of the State of Indiana. By then Reilly had retired from the practice of law, so the practice was renamed Craig, Ruckelshaus, Rhetts & O'Connor. After the departure of Gov. Craig and Charles Rhetts years later, the firm's name was changed to Ruckelshaus, O'Connor & Ruckelshaus. Shortly thereafter, former Indiana Supreme Court Justice Arch Bobbitt joined the partnership, and the name was again changed to Ruckelshaus, Bobbitt & O'Connor.
Upon his graduation from law school, Jack Ruckelshaus joined the firm. During the 1960's, both Jack and his brother, Bill, were members of the firm. In 1968, Bill moved to Washington, D.C. to accept an appointment with the U.S. Department of Justice. Bill would eventually serve as Acting Attorney General, Acting FBI Director and first Director of the Environmental Protection Agency.
Paul G. Roland joined the firm in 1968, and William A. Hasbrook in 1974. The firm name was thereafter changed to Ruckelshaus, Roland, Hasbrook & O'Connor. John F. Kautzman joined the firm in 1985, Leo T. Blackwell in 1991, and M. Elizabeth Bemis in 1992. Each of these individuals are now partners with the firm. In the year 2000, the firm changed to Ruckelshaus, Roland, Kautzman, Blackwell & Hasbrook. After over one hundred years of legal service to the Indianapolis community, the current firm Ruckelshaus Kautzman Blackwell Bemis & Hasbrook looks forward to its next century of service.
