Magirus GmbH is a truck manufacturer based in Ulm, Germany, founded by Conrad Dietrich Magirus (1824–1895). It was formerly known as Klöckner Humboldt Deutz AG, maker of the Deutz engines, so the brand commonly used was Magirus Deutz, and for a short time Klöckner. Most trucks from Magirus were also known as Magirus-Deutz. The logo of Magirus Deutz was a stylised M with a sharp, long centre point to represent the spire of Ulm Minster.
