High Quality Content by WIKIPEDIA articles! Rudolf Otto (September 25, 1869 6 March 1937) was an eminent German Lutheran theologian and scholar of comparative religion. Born in Peine near Hanover, Otto attended the Gymnasium Andreanum in Hildesheim and studied at the universities of Erlangen and Göttingen, where he wrote his dissertation on Martin Luther's understanding of the Holy Spirit, and his habilitation on Kant. By 1906, he held a position as extraordinary professor, and in 1910 he received an honorary doctorate from the University of Giessen. In 1915, he became ordinary professor at the University of Breslau, and in 1917, at the University of Marburg's Divinity School, then one of the most famous Protestant seminaries in the world. Although he received several other calls, he remained in Marburg for the rest of his life. He retired in 1929 and died of pneumonia eight years later, after he had suffered serious injuries falling some 20 m from a tower. Persistent but unconfirmed rumors identified this as a suicide attempt. He is buried in Marburg cemetery.
