Konrad Bernhard Schramm (23 August 1822, in Krefeld – 15 January 1858, in Saint Helier) was a German socialist revolutionary and as a result a member of the Communist League.
Following the suppression of the uprisings of 1848 and 1849, Schramm refugeed to London, England in 1849.
Schramm was also a friend and an associate of both Karl Marx and Frederick Engels.
In 1850, he challenged August Willich, an opponent of Marx, to a duel.
Schramm received a bullet wound to the head, but survived.
