Magirus GmbH[1] is a truck manufacturer based in Ulm, Germany, founded by Conrad Dietrich Magirus (1824–1895). The parent company was Klöckner Humboldt Deutz AG, maker of the well-known Deutz engines, so the brand commonly used was Magirus Deutz, and for a short time Klöckner. The logo of Magirus Deutz was a stylised M with a sharp, long centre point to represent the spire of Ulm Minster.
