In 1908 brothers David R. Williams and S. Miller Williams, Jr. were working for a contractor with an assignment to pave sidewalks in Fort Smith, Arkansas. The contractor abandoned the job when funding was delayed, but the brothers went ahead and took care of it. They then started The Williams Brothers Corporation, providing construction services, particularly for steel pipelines.

In 1919 they moved to Tulsa, Oklahoma, the oil and gas epicenter of the U.S. Within a matter of time, they began building pipelines for petroleum and natural gas. After many years, they graduated to cross-country pipelines. In 1949 they sold the firm to their nephew John, and it was renamed Williams Brothers Company. In 1957 it went public. By the 1960s it had become a leader in its sector.

In the decade that followed the company expanded its portfolio through service development and acquisitions. In 1966 it purchased Great Lakes Pipe Line Company, the then-largest petroleum products pipeline in the U.S. In 1971 it acquired The Suburban Companies, a liquid propane gas retailer. That same year, recognizing it had diversified, it was renamed The Williams Companies.
