Dr. David Hallenbeck (1941 - 2007)

Regretfully, Professor Emeritus Dr. David Hallenbeck passed away unexpectedly in April of
2007. Professor Hallenbeck served in our Department of Mathematical Sciences for over 30
years before his retirement in 2003. He had a distinguished career, with important contributions
in research, service and teaching during his tenure as a faculty at the University of Delaware.
He was also well-known for his expertise and love of birds. More details on Dr. Hallenbeck's
rich life can be found in our
Spring 2007 Newsletter.
A memorial fund honoring Professor Hallenbeck has been established, at the request of his family,
with the goal of funding a seminar series for the graduate students in the Department of Mathematical
Sciences. For details on how to donate to this fund, please see the
Spring 2007 Newsletter.
