Buchanan Ingersoll & Rooney, founded just seven years after The Legal Intelligencer, is one of the longest-standing and prosperous law firms in the commonwealth of Pennsylvania. Throughout the years, both The Legal and Buchanan Ingersoll have seen the legal industry evolve far beyond what either of their founders could have imagined. And both have successfully transformed their approach to legal service delivery.

History of Buchanan Ingersoll & Rooney

Buchanan’s roots began in Pittsburgh in 1850, when Moses Hampton and his son set up a legal shop in Pittsburgh. The present firm began to take shape at the turn of the century with William Watson Smith and John B. Gordon. In 1912, they were joined by John G. Buchanan, a highly revered appellate lawyer and, several years later, by Frank B. Ingersoll, a corporate finance attorney.
