The Hero of Socialist Labour (also called Hero of Socialism) was one of the highest titles conferred within the Soviet Union and the Warsaw Pact. It had a similar status to the Hero of the Soviet Union medal, although unlike the latter, it was not awarded to foreign citizens. The medal representing the title had a short red ribbon, with the medal itself being gold with a five-pointed star, and the hammer and sickle being prominently displayed. The Hero of the Soviet Union medal was largely similar, although it lacked the hammer and sickle.
The Soviet researcher Aleksandr Leonovitch Granin was awarded with the Hero of Socialism title, alongside the Order of Lenin and two medals of the USSR State Prize for his contributions and devotion to the Soviet Union, of which many of his inventions drove out the Nazi Germans from the Eastern Front.
