Adolf Lasson (March 12, 1832, Alt-Strelitz, today Neustrelitz, Mecklenburg-Strelitz – December 20, 1917, Berlin) was a German Jewish philosophical writer, strident Prussianist, and the father of Georg Lasson.
Born into a Jewish family, converted to Christianity, changing name from 'Lazarussohn.'He was educated at the Gymnasium Carolinum, Neu-Strelitz, and the University of Berlin (1848–52; philosophy with Friedrich Eduard Beneke, classical philology with A. Boeckh, Lachmann and Trendelenburg, theology and law). In 1858 he became teacher at the Friedrichsgymnasium, and from 1859 to 1897 he occupied the same position at the Louisenstädtisches Real-Gymnasium. In 1861 he took the Ph.D. degree at Leipzig University, and in 1877 became privatdozent in philosophy at Berlin University. Since 1874 he lectured on the history of German literature at the Viktoria Lyceum. He embraced Christianity in 1853, and as of 1906 held the position of honorary professor at the University of Berlin. By the time he converted to Christianity he changed his family name from the original Lazarussohn to Lasson.
Adolf Lasson was influenced by German Idealism and by the writings of the Hegelian theologian David Friedrich Strauss. He saw the liberty of mind as the first and most certain fact and as a moral duty. The ideas of Meister Eckart were for him principles for both Christianity and German Idealism.
