Charles Bernard Bell, Jr., was born into a family who had relations to teach, collectively, for more than 400 years. In 1947, Bell earned, at the age of 19, his B.S. degreee in mathematics and statistics from Xavier University. In 1948, he earned a MS degree from the University of Notre Dame and earned his Ph.D. in 1953 from the same university.
In 1951 he accepted a position as a Research Engineer with the Douglas Aircraft Company. He remained with Douglas until 1955. He returned to his undergraduate alma mater, Xavier University, as an assistant professor of mathematics and physics for the next two years (195557). In the fall of 1957, Dr. Bell went to Stanford University as a Research Associate in statistics and as mathematics instructor for one year (19571958). In 1958 he joined the faculty of San Diego State University where he remained until 1966; he was officially on leave in Europe from 19641966. The summer of 1964 was spent at The Mathematics Institute in Amsterdam. The 196465 academic year was spent at the University of Madrid and the summer of 1965 was spent at the University of Vienna. The 196566 academic year was spent at the Institute of Statistics at the University of Paris and the 1966 summer was spend at the University Erlangen in Germany.
Dr. Bell accepted a position as Professor of Mathematics and Statistics at Case Institute of Technology, and remained there for two years (196668) through the merger with Western Reserve University where he produced two Ph.D. students (Paul Smith and James Warner). He joined the faculty at the University of Michigan in Ann Arbor in 1968; remaining there until 1971. During the summer of 1968, Bell worked with African Mathematicians in Marsabit, Kenya and with Indian mathematicians in Calcutta, India. Additionally, during the summer of 1969, he spend time in Nigeria developing courses in mathematics for teachers.
Bell was a professor of mathematics at Tulane University from 19711977. During the summer of 1972, he was at the University of Gutenberg in Germany, and for the 197576 academic year, he took a leave of absence and spent the time at the National Science Foundation. From 1977 to 1981, Bell was a professor of Biostatistics at the University of Washington in Seattle. In 1981 he returned to San Diego State University as a professor of Mathematical Sciences. Except an eighteen month period in 19901991, when Bell was on leave at Stanford University, he remained at San Diego State until his retirement in June of 1992.
Research
Mathematics Reviews lists 39 papers by Charles Bell, a first rate career in his areas of specialty: nonparametric statistics, stochastic processes and related application areas. As they worked in the same area, it is curious whether Charles Bell and David Blackwell collaborated. I know of just a few joint projects of the two African American mathematicians:
Bell, C. B.; Blackwell, David; Breiman, Leo On the completeness of order statistics . Ann. Math. Statist. 31 1960 794797.
