Alfred Nobel's father, Immanuel, invented the underwater mine, built Russia's first rolling mill and constructed its first propeller-driven steamship. Robert and Ludvig Nobel, Alfred's brothers, developed the Russian oil industry at Baku and in 1914 their company Bratja Nobel--which had come to be known as Branobel--alone produced a quarter of the world's output of petroleum.
