The following is a history of the Sinclair Oil Corporation. From its founding by Harry F. Sinclair in 1916, Sinclair has grown to become one of the largest and most respected oil companies in the United States.

Our online history and photo album includes many pictures that are preserved in high quality here for your enjoyment. Because of the quality and quantity of photographs, download time may exceed 30 seconds or more per page. This history is intended for the true collector, fan, employee, former employee and those who have received inspiration from Sinclair and the "Dino" logo throughout their lifetime.

This illustrated history is dedicated to the men and women who made Sinclair what it is today. In their work they established and enjoyed a extraordinary fellowship. In their work they have grown a fierce loyalty to each other, and to that corporate entity that proudly flies the Sinclair banner. We thank you.
