Question: Who, Dmitri Egorov or Vladimir Berkovich, is a mathematician at the Weizmann Institute of Science?
Context: Harry Levine (August 1, 1895 – May 1, 1977) was the Massachusetts President and Chairman of the Board of the U.S. Plastic and Chemical Company.  He made major, multifaceted contributions to the creation and development of the State of Israel, related primarily to the facilitation of the construction and import of Uzi submachine guns into then British-Mandated Palestine.  He played a central role in the founding of the Weizmann Institute of Science; he provided initiatives for the practical application of science research there, and was a pioneer of a science-based industrial complex in Rehovot, adjacent to the Weizmann Institute, which was the first of its kind in Israel. Matematicheskii Sbornik (Russian: Математический сборник , abbreviated "Mat.  Sb.")  is a peer reviewed Russian mathematical journal founded by the Moscow Mathematical Society in 1866.  It is the oldest successful Russian mathematical journal.  The English translation is "Sbornik: Mathematics".  It is also sometimes cited under the alternative name "Izdavaemyi Moskovskim Matematicheskim Obshchestvom" or its French translation "Recueil mathématique de la Société mathématique de Moscou", but the name "Recueil mathématique" is also used for an unrelated journal, "Mathesis".  Yet another name, "Sovetskii Matematiceskii Sbornik", was listed in a statement in the journal in 1931 apologizing for the former editorship of Dmitri Egorov, who had been recently discredited for his religious views; however, this name was never actually used by the journal. Gerhard Martin Julius Schmidt (born, 21 August 1919 in Berlin – died July 12, 1971 in Zurich, buried in Rehovot), organic chemist and chemical crystallographer, director of the Weizmann Institute of Science in the late 1950s and again in the late 1960s.  Schmidt was the founder of X-ray crystallography at the Weizmann Institute and in Israel – a field in which Weizmann Institute’s Professor Ada Yonath was awarded the Nobel Prize in Chemistry for 2009. The Davidson Institute of Science Education is a public nonprofit organization aimed at promoting and nurturing the scientific, mathematical and technological education in Israel.  Serving as the educational arm of the Weizmann Institute of Science, the Davidson Institute develops, evaluates and provides a wide variety of educational programs for teaching and learning science and mathematics at all ages and levels.  It is located on campus of the Weizmann Institute in Rehovot. Zelig Eshhar is an Israeli immunologist at the Weizmann Institute of Science and at the Tel Aviv Sourasky Medical Center.  He has been the Chairman of the Department of Immunology at the Weizmann Institute, serving two terms during the 1990s and 2000s.  He received his B.Sc.  and M.Sc.  from the Hebrew University of Jerusalem, and his Ph.D. from the Weizmann Institute. Vladimir Berkovich is a mathematician at the Weizmann Institute of Science who introduced Berkovich spaces. His Ph.D. advisor was Yuri I. Manin.  Berkovich was a visiting scholar at the Institute for Advanced Study in 1991-92 and again in the summer of 2000. In measure theory, an area of mathematics, Egorov's theorem establishes a condition for the uniform convergence of a pointwise convergent sequence of measurable functions.  It is also named Severini–Egoroff theorem or Severini–Egorov theorem, after Carlo Severini, an Italian mathematician, and Dmitri Egorov, a Russian physicist and geometer, who published independent proofs respectively in 1910 and 1911. David Peleg (Hebrew: דוד פלג‎ ‎ ) is an Israeli computer scientist.  He is a professor at the Weizmann Institute of Science, holding the Norman D. Cohen Professorial Chair of Computer Sciences, and the present dean of the Faculty of Mathematics and Computer Science in Weizmann Institute. Dmitri Fyodorovich Egorov (Russian: Дми́трий Фёдорович Его́ров ; December 22, 1869 – September 10, 1931) was a Russian and Soviet mathematician known for significant contributions to the areas of differential geometry and mathematical analysis.  He was President of the Moscow Mathematical Society (1923 — 1930). The Weizmann House (Hebrew: בית ויצמן‎ ‎ ) was the home of the first President of Israel, Chaim Weizmann, and first First Lady, Vera Weizmann.  The house sits atop a hill in Rehovot, and is now part of the Weizmann Institute of Science.  The house was designed by Jewish architect Erich Mendelsohn, and recognized as a masterpiece.
