Heramba Lal Gupta( C.1884-1950) was an Indian Nationalist linked to the Berlin Committee and the Ghadar Party extensively involved in the Hindu–German Conspiracy, who later turned a British agent and passed in intelligence on Mahendra Pratap's Kabul Government. He was the son of Umesh Chandradasgupta of Kolkata. He left in 1911 to London for studies, and got involved in revolutionary activities. Janice Mc Kinnon and Stephen Mc Kinnon in their book, Agnes Smedley:The Life and Times of An American Radical, accuse that Gupta raped the American journalist and revolutionary, Agnes Smedley. The rape has been described in her autobiographical novel, Daughter of Earth.
