The Cadillac Motor Company was founded by the notable automotive pioneer Henry Leland in 1902 in Detroit, Michigan. Leland had previously worked for several manufacturers, and his expertise was pivotal in establishing Cadillac as a leader in precision automobile manufacturing. The company emerged out of the former Detroit Automobile Company, which had previously struggled to find its footing in the burgeoning automotive landscape. By focusing on quality craftsmanship and advanced manufacturing techniques, Cadillac quickly distinguished itself from its contemporaries.

In 1903, Cadillac produced its first car, the Cadillac Model A, which was notable for its innovative features such as interchangeable parts, a concept that was revolutionary at the time. This approach to manufacturing not only enhanced the brand's reputation but also contributed significantly to the standardization processes in the automotive industry. Cadillac was among the first companies to adopt mass production techniques, aligning with and eventually leading developments in the automotive assembly line inspired by Henry Ford’s production methods.

Within a few years, Cadillac solidified its position as America's luxury car manufacturer, winning the first-ever Dewar Trophy in 1908 for its precision engineering. This established not only a standard for Cadillac itself but also for the entire automotive industry. The company began to cater more profoundly to affluent consumers, and its vehicles became synonymous with luxury, quality, and technological advancement. Throughout the years, Cadillac has introduced several innovations, including electric starters and advanced automotive accessories that paved the way for the modern automotive experience.
