CUMMINS INC.

The Cummins Engine Company was founded in Columbus, Indiana on February 3, 1919, by mechanic Clessie Cummins and banker William Glanton Irwin. The company focused on developing the diesel engine, which was invented 20 years earlier. Despite several well-publicized endurance trials, it was not until 1933 that their Model H engine, used in small railroad switchers, proved successful.

In the 1960s, the company opened an assembly plant in Shotts, Scotland (closed in 1996). By 2013, Cummins had operations in 197 countries and territories.
