Braddock, Dunn & McDonald, later known as BDM, then BDM International, was a technical services firm founded in 1959 in New York City. Its founders were Dr. Joseph V. Braddock, Dr. Bernard J. Dunn, and Dr. Daniel F. McDonald, who each received a PhD from Fordham University in the Bronx, New York. In 1997, TRW purchased BDM, and in 2002 Northrop Grumman bought TRW. Move to Texas Within a year of its founding, the company moved to El Paso, Texas, to be close to the U.S. Army's Air Defense Center at Fort Bliss, Texas, the White Sands Missile Range in New Mexico, and Holloman Air Force Base, also in New Mexico. The founders offered their experience in missile guidance, applied optics, electronic instrumentation, and radiation physics to the U.S. Defense Department, primarily to the U.S. Army.

He led the company through a time of rapid growth and expansion.

Along with Western Union and Honeywell, BDM was one of the first firms to locate in the Westpark section of Tysons Corner, occupying buildings on Jones Branch Drive (ca. 1978) and Westbranch Drive (ca. 1980). Rapid growth The company grew rapidly, along with Tysons Corner. In the early 1960s Tysons Corner was a sleepy crossroads, but has since grown into a classic "edge city", and a home of many government and military contractors. Williams promoted the area as a suitable place for technology-oriented firms. Tysons Corner and the surrounding towns became the home of many of BDM's competitors, including Planning Research Corporation, DynCorp International, and CACI. Although all competed with BDM, in the buildup of defense budgets in the
