Professor Dr. Siegfried Schach (born 09.09.1936) studied mathematics and economics in Tübingen, Vienna, Frankfurt, Berlin and Minneapolis.
He then held professorships at Stanford University (1967 to 1968) and Johns Hopkins University (1968-1972).
Mr. Schach became acquainted with the statistical landscape there from the ground up through his many years of residence in the United States. He was particularly instrumental in the development of biometric and medical applications in Dortmund. Many positions in Germany in these areas are now filled by his students.
Mr. Schach declined a call to the University of Heidelberg in 1982.
From 1972 to 2001, Mr. Schach held the chair of "Mathematical Statistics and Applications I" ("Mathematical Statistics and Biometric Applications") at the Department of Statistics.
