Williams Companies, Inc.
A builder of natural gas infrastructure, Williams runs interstate pipelines like Transco, plus gathering, processing, and marketing operations that move gas and natural gas liquids to roughly 800 customers across the United States. It began in 1908 when brothers Miller and David Williams took over an abandoned sidewalk-paving job in Fort Smith, Arkansas, then rode the Oklahoma oil boom into pipeline construction and moved to Tulsa. The company still bears the family name from those early days.
