Longview was named for the "long view" from Rock Hill when surveyors laid off the townsite in 1870, and it was incorporated on June 24, 1871. It became the county seat of Gregg County and also a railroad, agricultural, and lumber center. Its history includes an 1894 bank robbery, the last raid of the notorious Dalton Gang. It was an early home of Governors Thomas M. Campbell and James S. Hogg. Since the nearby 1931 Lathrop Well extended the East Texas oil field into the world's largest, it has been a petroleum, financial, industrial, medical, cultural, and religious hub, and is home of LeTourneau College.
