The modern-day city of Longview was founded in 1869. In 1870, O.H. Methvin, Sr. sold 100 acres (40 ha) to the Southern Pacific Railroad for one dollar to persuade them to build their line in the direction of land he owned. Later that year, he sold another 100 acres (40 ha) for $500 in gold. He hoped the coming of the railroad would increase the value of the rest of his land.

Two railroad surveyors coined the name of the town when they stated, "What a long view!" from the porch of Methvin's home. In June 1871, Longview was incorporated as the first town in Gregg County.

In 1884, the Mobberly Hotel opened for business servicing railroad travelers and as the center of social gatherings for Longview.

Mobberly was located in the junction part of town near the train depot. The hotel was destroyed by fire on June 13, 1965.[citation needed]
