Praeger.
(1834-1907), chemist; creator of the periodic table of elements.
Dmitry Mendeleyev was born in Tobolsk, Siberia, where his father was the director of the local gymnasium. In 1853 he enrolled in the Main Pedagogical Institute in St. Petersburg, which
trained secondary school teachers. His early interest in chemistry focused on isomorphism-the groups of chemical elements with similar crystalline forms and chemical properties. In 1856 he earned a magisterial degree from St. Petersburg University and was appointed a private docent at the same institution. In 1859 a state stipend took him to the University of Heidelberg for advanced studies in chemistry. In 1861 he returned to St. Petersburg University and wrote Organic Chemistry, the first volume of its kind to be published in Russian. He offered courses in analytical, technical, and organic chemistry. In 1865 he defended his doctoral dissertation and was appointed professor of chemistry, a position he held until his retirement in 1890.
In 1868, with solid experience in chemical research , he undertook the writing of The Principles of Chemistry, a large study offering a synthesis of contemporary advances in general chemistry. It was during the writing of this book that he discovered the periodic law of elements, one of the greatest achievements of nineteenth-century chemistry. In quality this study surpassed all existing studies of its kind. It was translated into English, French, and German. In 1888 the English journal Nature recognized it as “one of the classics of chemistry” whose place “in the history of science is as well-assured as the ever-memorable work of [English chemist John] Dalton.”
An international gathering of chemists in Karlsruhe in 1860 had agreed in establishing atomic weights as the essential features of chemical elements. Several leading chemists immediately began work on establishing a full sequence of the sixty-four elements known at the time. Mendeleyev took an additional step: he presented what he labeled the periodic table of elements, in which horizontal lines presented elements in sequences of ascending atomic weights, and vertical lines brought together elements with similar chemical properties. He showed that in addition to the emphasis on the diversity of elements, the time had also come to recognize the patterns of unity.
Beginning in the 1870s, Mendeleyev wrote on a wide variety of themes reaching far beyond chemistry. He was most concerned with the organizational aspects of Russian industry, the critical problems of agriculture, and the dynamics of education. He tackled demographic questions, development of the petroleum industry, exploration of the Arctic Sea, the agricultural value of artificial fertilizers, and the development of a merchant navy in Russia. In chemistry, he elaborated on specific aspects of the periodic law of elements, and wrote a large study on chemical solutions in which he advanced a hydrate theory, critical of Svante Arrhenius’s and Jacobus Hendricus van’t Hoff’s electrolytic dissociation theory. At the end of his life, he was engaged in advancing an integrated view of the chemical unity of nature. Mendeleyev saw the future of Russia in science and in a philosophy avoiding the rigidities of both idealism and materialism.

The Menshevik Party was a moderate Marxist group within the Russian revolutionary movement. The Mensheviks originated as a faction of the Russian Social Democratic Workers Party (RSDWP). In 1903, at the Second Party Congress, Yuli O. Martov proposed a less restrictive definition of party membership than Vladimir I. Lenin. Based on the voting at the congress, Lenin’s faction of the party subsequently took the name Bolshevik, or “majority,” and Martov’s faction assumed the name Menshevik, or “minority.” The party was funded by dues and donations. Its strength can be measured by proportionate representation at party meetings, but membership figures are largely speculative because the party was illegal during most of its existence.
Russian revolutionaries had embraced Marxism in the 1880s, and the Mensheviks retained Georgy Plekhanov’s belief that Russia would first experience a bourgeois revolution to establish capitalism before advancing to socialism, as Karl Marx’s model implied. They opposed any premature advance to socialism. A leading Menshevik theorist, Pavel Borisovich Akselrod, stressed the necessity of establishing a mass party of workers in order to assure the triumph of social democracy.

During the 1905 Revolution, which established civil liberties in Russia, Akselrod called for a “workers’ congress,” and many Mensheviks argued for cooperation with liberals to end the autocracy. Their Leninist rivals vested the hope for revolution in a collaboration of peasants and workers. Despite these differences, Bolsheviks and Mensheviks participated in a Unification Congress at Stockholm in 1906. The Menshevik delegates voted to participate in elections to Russia’s new legislature, the Duma. Lenin initially opposed cooperation but later changed his mind. Before cooperation could be fully established, the Fifth Party Congress in London (May 1907) presented a Bolshevik majority. Ak-selrod’s call for a workers’ congress was condemned. Soon afterward the tsarist government ended civil liberties, repressed the revolutionary parties, and dissolved the Duma.
From 1907 to1914 the two factions continued to grow apart. Arguing that the illegal underground party had ceased to exist, Alexander Potresov called for open legal work in mass organizations rather than a return to illegal activity. Fedor Dan supported a combination of legal and illegal work. Lenin and the Bolsheviks labeled the Mensheviks “liquidationists.” In 1912 rival congresses produced a permanent split between the two factions.
During World War I many Mensheviks were active in war industries committees and other organizations that directly affected the workers’ movement. Menshevik internationalists, such as Martov, refused to cooperate with the tsarist war effort. The economic and political failure of the Russian government coupled with continued action by revolutionary parties led to the overthrow of the tsar in February (March) 1917. The Menshe-viks and another revolutionary party, the Socialist Revolutionaries, had a majority in the workers’ movement and ensured the establishment of democratic institutions in the early months of the revolution. Since the Mensheviks opposed an immediate advance to socialism, the party supported the concept of dual power, which established the Provisional Government and the Petrograd Soviet. In response to a political crisis that threatened the collapse of the Provisional Government, Menshe-viks who wanted to defend the revolution, labeled defensists, decided to join a coalition government in April 1917. Another crisis in July did not persuade the Menshevik internationalists to join. Thereafter, the Mensheviks were divided on the Revolution. The Provisional Government failed to fulfill the hopes of peasants, workers, and soldiers.
Because the Mensheviks had joined the Provisional Government and the Bolsheviks were not identified with its failure, the seizure of power by the Soviets in November brought the Bolshevik Party to power. Martov’s attempts to negotiate the formation of an all-socialist coalition failed. Men-sheviks opposed the Bolshevik seizure of power, the dissolution of the Constituent Assembly, and the Treaty of Brest-Litovsk signed by the Bolsheviks, who now called themselves the Communist Party. Marginally legal, the Mensheviks opposed Allied efforts to crush the Soviet state during the civil war and, though repressed by the communists, also feared that counterrevolutionary forces might gain control of the government. Mensheviks established a republic in Georgia from1918 to 1921. At the end of the civil war, some workers adopted Menshevik criticisms of Soviet policy, leading to mass arrests of party leaders. In 1922 ten leaders were allowed to emigrate. Others joined the Communist Party and were active in economic planning and industrial development. Though Mensheviks operated illegally in the 1930s, a trial of Mensheviks in 1931 signaled the end of the possibility of even marginal opposition inside Russia. A Menshevik party abroad operated in Berlin, publishing the journal Sotsialis-tichesky Vestnik under the leadership of Martov. Dan emerged as the leader of this group after Mar-tov’s death in 1923. To escape the Nazis the Men-sheviks migrated to Paris and then to the United States in 1940, where they continued publication of their journal until 1965.
