Lorraine-Dietrich was a notable French company that produced cars and aircraft engines from 1896 to 1935. It was formed when Société Lorraine des Anciens Etablissements de Dietrich et Cie de Lunéville, a railway locomotive manufacturer established by Jean de Dietrich in 1884, diversified into car production. The company's production plants were split between Niederbronn-les-Bains, Alsace, and Lunéville, Lorraine, due to the Franco-Prussian War. Lorraine-Dietrich quickly established itself as a major player in the automotive industry, producing luxury cars and race cars that were renowned for their advanced engineering and high performance. The company also supplied aircraft engines during World War I. However, Lorraine-Dietrich struggled financially in the 1920s and 1930s, and ultimately ceased production in 1935. Despite its relatively short lifespan, Lorraine-Dietrich remains an important part of French automotive history, with many of its cars and engines now highly sought-after by collectors and enthusiasts.
