Question: Matthias Mann worked at Yale University in 1988 with an American research professor of analytical chemistry, who was born on what day?
Context: Joseph-Achille Mbembe, known as Achille Mbembe (born 1957), is a Cameroonian philosopher, political theorist, and public intellectual.  He was born near Otélé in French Cameroons in 1957.  He obtained his Ph.D. in history at the University of Sorbonne in Paris, France, in 1989.  He subsequently obtained a D.E.A. in political science at the Institut d’Etudes Politiques in the same city.  He has held appointments at Columbia University in New York, Brookings Institution in Washington, D.C., University of Pennsylvania, University of California, Berkeley, Yale University, Duke University and Council for the Development of Social Science Research in Africa (CODESRIA) in Dakar, Senegal.  He was Assistant Professor of History at Columbia University, New York, from 1988-1991, a Senior Research Fellow at the Brookings Institution in Washington, D.C., from 1991 to 1992, Associate Professor of History at the University of Pennsylvania from 1992 to 1996, Executive Director of the Council for the Development of Social Science Research in Africa (Codesria) in Dakar, Senegal, from 1996 to 2000.  Achille was also a visiting Professor at the University of California, Berkeley, in 2001, and a visiting Professor at Yale University in 2003.  He is currently a Research Professor in History and Politics at Harvard University's W.E.B. Dubois Research Institute. Isaac Mustafin (Russian: Исаак Савельевич Мустафин ) (1908–1968) was a Russian chemist and a doctor of chemical sciences.  All his life was connected to the Saratov State University: his only lengthy absence from his work place took place from June 23, 1941 to August 15, 1945, when he served in the army.  The life and activity of Professor Mustafin were reflected in a number of papers [1–7] and even monographs [8–9], including that in the series of scientific biographic literature of the Nauka publishing house [8].  (See also [10]).  The unusual biography and diversified interests of the scientist have attracted the attention of chemists, historians, philosophers, and writers.  In fact, a characteristic feature of I.S. Mustafin was the broad spectrum of his scientific interests: he successfully worked in analytical, organic, physical, and inorganic chemistry; bio- and geochemistry; and the philosophy and history of science.  In all these directions, he was interested in the key problems: in organic chemistry, the synthesis of new and the most important compounds; in bio- and geochemistry, the origin of fuel materials, coal and oil; and in analytical chemistry, the search for lows in the application of analytical reagents, the construction of a system for assessing the sensitivity and selectivity of analytical reactions, and the development of the theory of action of organic reagents in chemical analysis. Matthias Mann (born 10 October 1959) is a scientist in the area of mass spectrometry and proteomics.  Born in Germany he studied mathematics and physics at the University of Göttingen.  He received his Ph.D. in 1988 at Yale University where he worked in the group of John Fenn, who was later awarded the Nobel Prize in Chemistry.  After a postdoctoral fellowship at the University of Southern Denmark in Odense he became group leader at the European Molecular Biology Laboratory (EMBL) in Heidelberg.  Later he went back to Odense as a professor of bioinformatics.  Since 2005 he has been a director at the Max Planck Institute of Biochemistry in Munich.  In addition, he will also become a principal investigator at the newly founded "Novo Nordisk Foundation Center for Protein Research" in Copenhagen. Richard Neil Zare (born November 19, 1939, Cleveland, Ohio) is the Marguerite Blake Wilbur Professor in Natural Science and a Professor of Chemistry at Stanford University.  Throughout his career, Zare has made a considerable impact in physical chemistry and analytical chemistry, particularly through the development of laser-induced fluorescence (LIF) and the study of chemical reactions at the molecular and nanoscale level.  LIF is an extremely sensitive technique with applications ranging from analytical chemistry and molecular biology to astrophysics.  One of its applications was the sequencing of the human genome. Philip Juliber Elving (1913-1984) was a chemist who served on the faculty of Pennsylvania State University, Purdue University, and most notably the University of Michigan, where he was the Hobart Willard Professor of Chemistry.  He retired from Michigan, assuming professor emeritus status, in 1983.  His research was primarily in analytical chemistry, a subject he also taught for many years at Michigan.  Along with I. M. Kolthoff and J. D. Winefordner, he co-edited two popular series of monographs on analytical chemistry. Critical Reviews in Analytical Chemistry is a quarterly peer-reviewed scientific journal published by Taylor & Francis.  It was established in 1970 as "CRC Critical Reviews in Analytical Chemistry", obtaining its current name in 1989.  The journal covers research in all areas of analytical chemistry.  The editor-in-chief is Stephen E. Bialkowski (Utah State University). John Bennett Fenn (June 15, 1917December 10, 2010) was an American research professor of analytical chemistry who was awarded a share of the Nobel Prize in Chemistry in 2002.  Fenn shared half of the award with Koichi Tanaka for their work in mass spectrometry.  The other half of the 2002 award went to Kurt Wüthrich.  Fenn's contributions specifically related to the development of electrospray ionization, now a commonly used technique for large molecules and routine liquid chromatography-tandem mass spectrometry.  Early in his career, Fenn did research in the field of jet propulsion at Project SQUID, and focused on molecular beam studies.  Fenn finished his career with more than 100 publications, including one book. Goldschmiedt was born in Triest, Austria-Hungary.  He started studying economics at the business school in Frankfurt am Main, but then started attending science lectures in other educational institutions.  In 1869, he went back to Vienna, where part of his family lived, and studied chemistry at the University of Vienna.  There he attended lectures of Josef Redtenbacher and Franz Cölestin Schneider – the most prominent chemists of the time in Vienna.  In 1871, he moved to the University of Heidelberg, Germany.  There he received his PhD for work with Robert Wilhelm Bunsen and his assistant Blum in the field of inorganic analytical chemistry of minerals.  For a postdoctoral position, he joined the laboratory of Adolf von Baeyer at the University of Straßburg.  Goldschmiedt worked in the field of organic chemistry for two years, but he also studied mineralogy and crystallography with Paul Heinrich von Groth.  During that time, Emil Fischer and Franz S. Exner also worked with Baeyer in Straßburg.  For Goldschmiedt, the time in Straßburg ended abruptly because he joined the group of Schneiders at the University of Vienna.  After his habilitation in 1875, he was sent as official observer to the world fair in Philadelphia in 1876.  After visiting California, he went back to Vienna and married in 1886.  It took until 1890 for him to become assistant professor at University of Vienna, but only one year later he became full professor.  In 1891, Goldschmiedt moved to the German Charles-Ferdinand University in Prague and worked there for 20 years.  In the meantime, he received the Lieben Prize in 1892 and became a member of the Vorstand of Deutschen Chemischen Gesellschaft in 1900 and 1901.  In 1911, Goldschmiedt succeeded Zdenko Hans Skraup at the University of Vienna and was mostly involved in administrative tasks, such as supervising the construction of the laboratory building and reorganization of the institute.  Starting from 1914, his health deteriorated slowly but steadily, resulting in his eventual death on August 6, 1915. Reiner Salzer (born February 12, 1942 in Aue (Sachsen)) is a German chemist (Analytical Chemistry) and university teacher of Analytical Chemistry at the TU Dresden. Jiří Barek (born October 2, 1949, in Benešov, Czech Republic) is an electroanalytical chemist and university teacher of analytical chemistry.  He graduated from Charles University, Faculty of Science, Department of Analytical Chemistry in 1972, and obtained his PhD in 1976 from the same institution.  From 1977–1987 he served as a Lecturer, 1986–2006 as a Reader, and from 2006 he is a Professor at the Department of Analytical Chemistry, Faculty of Science, Charles University, Prague.  From 1993–1997 he served as the Deputy-Head and 2006–2012 as the Head of the Department of Analytical Chemistry, Charles University, Prague.
