C. Lorenz AG (1880–1958) was a German electrical and electronics firm primarily located in Berlin. It innovated, developed, and marketed products for electric lighting, telegraphy, telephony, radar, and radio. It was acquired by ITT in 1930 and became part of the newly founded company Standard Elektrik Lorenz (SEL) Stuttgart in 1958, when it merged with Standard Elektrizitätsgesellschaft and several other smaller companies owned by ITT. In 1987, SEL merged with the French companies Compagnie Générale d'Electricité and Alcatel to form the new Alcatel SEL.
