​​KBR was created in 1998 when M.W. Kellogg merged with Brown & Root Engineering and Construction creating one of the world's premiere engineering, procurement, construction (EPC) and services companies.   

M.W. Kellogg

In 1901, Morris Woodruff Kellogg opened M.W. Kellogg as a tiny pipe fabrication business in New York and grew it into a world-class engineering firm. Kellogg's engineering expertise and thirst for innovation led to the creation of new technologies and industry milestones, including the world's first catalytic cracking facility and Europe's first crude oil-based liquid ethylene cracking facility. In the 1960s, Kellogg revolutionized fertilizer production through the creation of a new ammonia process, making a rapid growth in global food production possible. Many of the innovations that originated in the Kellogg laboratory are now the foundation for the petroleum refining and petrochemical processing facilities — and remain a major part of KBR today. In the late 1980's M.W. Kellogg was acquired by Dresser Industries, which was then merged with Halliburton in 1998.

Brown & Root Engineering

Brown & Root Engineering and Construction, the pioneering international road builder and general contracting company, was started in 1919 when brothers George and Herman Brown partnered with Herman's brother-in-law, Dan Root, to create a Texas-based construction company. Brown and Root began building roads but quickly expanded into other areas. After the end of World War II, Brown & Root set its sights offshore. In 1947, the company achieved a global milestone when it constructed the first offshore oil platform 43 miles off the coast of Morgan City, LA. More industry firsts and record-setting projects would follow over the coming decades throughout the world and in its hometown of Houston.  

Brown & Root built many of Houston's landmark projects, including the Gulf Freeway, Rice University's football stadium, NASA, Minute Maid Park and other initiatives that helped shape Houston into the premier city it is today, as well as the refineries, petrochemical plants and offshore platforms that power the global economy. Many of the tools and resources now standard in the construction industry were created by Brown & Root. In 1962, Brown & Root was acquired by Halliburton.


In 2006, KBR reached a major milestone when the company separated from Halliburton and completed a successful initial public offering on the New York Stock Exchange. Today, KBR employs approximately 22,000 people globally with customers in more than 80 countries and operations in 40 countries.

In 2014, KBR streamlined operations to focus on its core strengths as a global technology, engineering, procurement and construction company serving the hydrocarbons and government services industries across three distinct global businesses: Technology & Consulting, Engineering & Construction, and Government Services.
