Boris Nemtsov, Russian academic and politician, First Deputy Prime Minister of Russia (d. 2015)
Boris Yefimovich Nemtsov (Russian: Бори́с Ефи́мович Немцо́в, IPA: [bɐˈrʲis jɪˈfʲiməvʲɪtɕ nʲɪmˈtsof]; 9 October 1959 – 27 February 2015) was a Russian physicist and liberal politician. He was involved in the introduction of reforms into the Russian post-Soviet economy. In the 1990s under President Boris Yeltsin, he was the first governor of the Nizhny Novgorod Oblast (1991–97). Later he worked in the government of Russia as Minister of Fuel and Energy (1997), Vice Premier of Russia and Security Council member from 1997 to 1998. In 1998, he founded the Young Russia movement. In 1998, he co-founded the coalition group Right Cause and in 1999, he co-formed Union of Right Forces, an electoral bloc and subsequently a political party. Nemtsov was also a member of the Congress of People's Deputies (1990), Federation Council (1993–97) and State Duma (1999–2003).

From 2000 until his death, he was an outspoken critic of Vladimir Putin. He criticized Putin's government as an increasingly authoritarian, undemocratic regime, highlighting widespread embezzlement and profiteering ahead of the Sochi Olympics, and Russian political interference and military involvement in Ukraine. After 2008, Nemtsov published in-depth reports detailing the corruption under Putin, which he connected directly with the President. As part of the same political struggle, Nemtsov was an active organizer of and participant in Dissenters' Marches, Strategy-31 civil actions and rallies "For Fair Elections".

Nemtsov was assassinated on 27 February 2015, beside his Ukrainian partner Anna Durytska, on a bridge near the Kremlin in Moscow, with four shots fired from the back. At the time of his assassination, he was in Moscow helping to organize a rally against the Russian military intervention in Ukraine and the Russian financial crisis. At the same time, he was working on a report demonstrating that Russian troops were fighting alongside pro-Russian rebels in eastern Ukraine, which the Kremlin had been denying, and was unpopular externally but also in Russia. In the weeks before his death, he expressed fear that Putin would have him killed. In late June 2017, five Chechnya-born men were found guilty by a jury in a Moscow court for agreeing to kill Nemtsov in exchange for 15 million rubles (US$253,000); neither the identity nor whereabouts of the person who hired them is officially known.After Nemtsov's murder, Serge Schmemann of The New York Times paid tribute to him in an article headlined "A Reformer Who Never Backed Down." Schmemann wrote: "Tall, handsome, witty and irreverent, Mr. Nemtsov was one of the brilliant young men who burst onto the Russian stage at that exciting moment when Communist rule collapsed and a new era seemed imminent." Julia Ioffe, writing for The New York Times, described Nemtsov after his death as "a powerful, vigorous critic of Vladimir Putin", who was "a deeply intelligent, witty, kind and ubiquitous man" who "seemed to genuinely be everyone's friend".
