Vladimir Igorevich Arnold was a Soviet and Russian mathematician. He is best known for the Kolmogorov–Arnold–Moser theorem regarding the stability of integrable systems, and contributed to several areas, including geometrical theory of dynamical systems, algebra, catastrophe theory, topology, real algebraic geometry, symplectic geometry, differential equations, classical mechanics, differential-geometric approach to hydrodynamics, geometric analysis and singularity theory, including posing the ADE classification problem.
Hilbert's problems are 23 problems in mathematics published by German mathematician David Hilbert in 1900. They were all unsolved at the time, and several proved to be very influential for 20th-century mathematics. Hilbert presented ten of the problems at the Paris conference of the International Congress of Mathematicians, speaking on August 8 at the Sorbonne. The complete list of 23 problems was published later, in English translation in 1902 by Mary Frances Winston Newson in the Bulletin of the American Mathematical Society. Earlier publications appeared in Archiv der Mathematik und Physik.
David Bryant Mumford is an American mathematician known for his work in algebraic geometry and then for research into vision and pattern theory. He won the Fields Medal and was a MacArthur Fellow. In 2010 he was awarded the National Medal of Science. He is currently a University Professor Emeritus in the Division of Applied Mathematics at Brown University.
Sergei Petrovich Novikov was a Soviet and Russian mathematician, noted for work in both algebraic topology and soliton theory. He became the first Soviet mathematician to receive the Fields Medal in 1970.
Earl Russell Browder was an American politician, spy for the Soviet Union, communist activist and leader of the Communist Party USA (CPUSA). Browder was the General Secretary of the CPUSA during the 1930s and first half of the 1940s. During World War I, Browder served time in federal prison as a conscientious objector to conscription and the war. Upon his release, Browder became an active member of the American Communist movement, soon working as an organizer on behalf of the Communist International and its Red International of Labor Unions in China and the Pacific region.
Jacob Golos was a Ukrainian-born Bolshevik revolutionary who became an intelligence operative in the United States on behalf of the USSR. A founding member of the Communist Party of the United States of America (CPUSA), circa 1930 Golos became involved in the covert work of Soviet intelligence agencies. He participated in procuring American passports by means of fraudulent documentation, and the recruitment and coordination of activities of a broad network of agents.
As early as the 1920s, the Soviet Union, through its GRU, OGPU, NKVD, and KGB intelligence agencies, used Russian and foreign-born nationals, as well as Communists of American origin, to perform espionage activities in the United States, forming various spy rings. Particularly during the 1940s, some of these espionage networks had contact with various U.S. government agencies. These Soviet espionage networks illegally transmitted confidential information to Moscow, such as information on the development of the atomic bomb. Soviet spies also participated in propaganda and disinformation operations, known as active measures, and attempted to sabotage diplomatic relationships between the U.S. and its allies.
Donald Niven Wheeler (1913–2002) was an American social activist, teacher, and Communist Party member, as well as an alleged Soviet spy.
Gilbert Ames Bliss,, was an American mathematician, known for his work on the calculus of variations.
Sir William Felix Browder, is an American-born British financier and political activist. He is the CEO and co-founder of Hermitage Capital Management, the investment advisor to the Hermitage Fund, which was formerly the largest foreign portfolio investor in Russia. The Hermitage Fund was founded in partnership with Republic National Bank, with $25 million in seed capital. The fund, and associated accounts, eventually grew to $4.5 billion of assets under management. In 1997, the Hermitage Fund was the best-performing fund in the world, up by 238%. Browder's primary investment strategy was shareholder rights activism. Browder took on large Russian companies such as Gazprom, Surgutneftegaz, Unified Energy Systems, and Sidanco. In retaliation, on 13 November 2005, Browder was refused entry to Russia, deported to the UK, and declared a threat to Russian national security.
José Adem was a Mexican mathematician who worked in algebraic topology, and proved the Adem relations between Steenrod squares.
Henry Burchard Fine was an American university dean and mathematician.
William Browder is an American mathematician, specializing in algebraic topology, differential topology and differential geometry. Browder was one of the pioneers with Sergei Novikov, Dennis Sullivan and C. T. C. Wall of the surgery theory method for classifying high-dimensional manifolds. He served as president of the American Mathematical Society until 1990.
Morris H. Childs was a Ukrainian-American political activist and American Communist Party functionary who became a Soviet espionage agent (1929) and then a double agent for the Federal Bureau of Investigation (1952) until leaving both services by 1982. Beginning in 1958, Childs acted as a secret courier on behalf of the American party, briefing Soviet officials on political affairs in the American party and carrying funds to support the American Communist movement from Moscow to New York City, reporting details all the while to his FBI handlers. Over the course of two decades of activity in this role, Childs played a major part in the transfer of more than $28 million in Soviet subsidies to the American movement. For his activity as a courier on behalf of the Soviet government, Childs was awarded the Order of the Red Banner in 1975. His work as a spy for the American intelligence community was recognized in 1987 when Childs was awarded the Presidential Medal of Freedom by President Ronald Reagan.
John Coleman Moore was an American mathematician. The Borel−Moore homology and Eilenberg–Moore spectral sequence are named after him.
Alejandro Adem is a professor in the Department of Mathematics at the University of British Columbia and President of the Natural Sciences and Engineering Research Council of Canada. Previously he was Director of the Pacific Institute for the Mathematical Sciences for the period 2008–2015 and during 2015-2019 was the CEO and Scientific Director of Mitacs. In 2024 he was reappointed to a second five-year term as President of NSERC.
Andrew Browder was an American mathematician at Brown University.
John Lowenthal (1925–2003) was a 20th-century American lawyer, civil servant, law professor, and documentary filmmaker, who defended the name and reputation of family friend Alger Hiss almost all his life.
Andrew Alexander Ranicki was a British mathematician who worked on algebraic topology. He was a professor of mathematics at the University of Edinburgh.
