Karl Eduard Nobiling (10 April 1848 – 10 September 1878) was a German attempted assassin, who in 1878 made an attempt on the life of Emperor Wilhelm I. Nobiling was born in Kolno near Birnbaum (Międzychód) in the Prussian Province of Posen, where his father was the tenant of the local manor. He attended school in Züllichau (Sulechów) and studied political science and agriculture at the University of Halle and Leipzig University, where he received a doctor's degree in 1876. During his studenthood he may have had some minor contact with Socialist circles, though an affiliation with the contemporary Social democratic movement has not been conclusively established.
