Locke Lord LLP is an American law firm of approximately 650 lawyers with 11 domestic and two overseas offices. Locke Lord was formed on October 2, 2007, after the combination of Texas-based Locke Liddell & Sapp PLLC and Lord Bissell & Brook LLP, a national law firm headquartered in Chicago. The firm changed its name from Locke Lord Bissell & Liddell LLP to Locke Lord LLP on September 27, 2011.
Legacy Locke Liddell & Sapp
The oldest component of Locke Lord traces back through the legacy Locke Liddell & Sapp side to a firm founded in Dallas, Texas by Maurice Locke in 1891. It is the second oldest continuously operating firm in Dallas. The firm became Locke & Locke when Maurice Locke's sons ran the practice, and his grandsons renamed it Locke Purnell. In 1916, another predecessor firm, Huggins & Kayser, began developing independently in Houston, Texas. Frank Liddell, known as an outstanding trial lawyer, became a partner in the Houston-based Huggins & Kayser firm in 1921. Charles Sapp then joined the predecessor Houston firm in 1946. Back in Dallas, six young attorneys spun out of the oldest firm in Dallas and formed another predecessor firm in 1965 under the name Rain Harrell & Emery. In 1987, Maurice Locke’s original Dallas firm and the newer Rain Harrell Emery Young & Doke firm merged to create one of the then-largest law firms in the Southwest: Locke Purnell Rain Harrell. In 1999, the Dallas firm Locke Purnell Rain Harrell merged with the Houston firm of Liddell Sapp Zivley Hill & LaBoon to form Locke Liddell & Sapp. At the time, this was the largest law firm merger in United States legal history. Locke Liddell & Sapp continued to exist until the 2007 national merger with Chicago-based Lord Bissell & Brook.
Legacy Locke Liddell & Sapp was known for its work in the real estate investment trust and energy sectors.
Legacy Lord Bissell & Brook
Legacy Lord Bissell & Brook began in 1914 when three lawyers—Donald Richberg, Harold L. Ickes, and John Lord—formed a Chicago law practice. In 1924, John Lord left that firm to open a Chicago predecessor firm by the name of Lord, Wire & Cobb. Cushman Bissell, Sr. joined Lord’s firm in 1931 as a named partner. In 1954, Herbert Brook became a named partner and the firm’s name changed from Lord Lloyd & Bissell to its legacy name—Lord Bissell & Brook. The firm would operate under that name until its 2007 merger with Texas-based Locke Liddell & Sapp.
Legacy Lord Bissell & Brook was known for its work in insurance and reinsurance litigation, particularly in the Chicago market. The firm was known as an “insurer-side firm” that tended to represent insurance companies and not individual policy holders.
Merger of legacy firms
In May 2007, management of each firm first proposed that legacy Locke Liddell & Sapp and legacy Lord Bissell & Brook merge into one national firm. On September 12, 2007, the partnership of each firm approved the merger, to be effective October 2, 2007. Locke Lord Bissell & Liddell LLP gross revenues and size place it within The American Lawyer’s “AmLaw 100” annual rankings of the top United States law firms.
