Overview
Dmitri Ilyich Ulyanov (; – 16 July 1943) was a Russian and Soviet physician and revolutionary, the younger brother of Aleksandr Ulyanov and Vladimir Lenin.
As a medical student at Lomonosov Moscow State University, he became involved with revolutionary activity and joined the illegal Marxist Rabochiy soyuz ("Workers' Union"). He was first arrested in 1897. The following year he was exiled to Tula, then Podolsk, where he was put under police supervision (equivalent to modern probation). As his brother's renown grew, he endured countless arrests. In 1900 he became a correspondent of Iskra. The following year he graduated from the medical school of the University of Tartu.
As a doctor and a Marxist, Ulyanov sought to apply his medical training to the revolutionary struggle. During the Revolution of 1905 he provided medical aid to strikers in Simbirsk. He became a trusted cadre of the Russian Social Democratic Workers' Party and was a delegate to its 2nd Congress. He served as the representative of the Central Committee in Kiev. His duties carried him throughout Russia and Ukraine, first to Serpukhov, then to Feodosiya and Crimea.
At the beginning of the First World War, Ulyanov was mobilized into the army. He served as a medical officer in Sevastopol, in Odessa, and on the Romanian front, continuing his revolutionary activities on the side. In 1916 he married Antonia Ivanovna Neshcheretova. He had a son, Viktor, and a daughter, Olga.
