Question: Matthias Mann worked at Yale University in 1988 with an American research professor of analytical chemistry, who was born on what day?

 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. Matthias Mann (born 10 October 1959) is a scientist in the area of mass spectrometry and proteomics.  In addition, he will also become a principal investigator at the newly founded "Novo Nordisk Foundation Center for Protein Research" in Copenhagen. <SEP> 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. <SEP> 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. <SEP>  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. 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.
