Robert Sheldon Harte

Robert Sheldon Harte (1915 – 1940) was an American Communist who worked as one of Leon Trotsky’s assistants and bodyguards in Coyoacán, Mexico. During the Stalinist attack against Trotsky’s household on May 24, 1940, Harte was abducted and later murdered by the Stalinist agents. Harte's body was found alongside the road to Desierto de los Leones and Trotsky commissioned a plaque and had it placed at the front of the house with the text: "In Memory of Robert Sheldon Harte, 1915-1940, Murdered by Stalin."

In "The Assassination of Trotsky", he is portrayed under the name "Sheldon Harte."
