I retired in 2011 but (as of 2018) continue to teach, mainly the course CS2110, "OO Programming and Data Structures", which in Spring 2018 had 609 (sic) students.

I received an BS in Math from Queens College, NY in 1960, MS in Math from Illinois in 1963, and Dr. rer. nat. (pronounced ''rare nut'') from MIT ---the Munich Institute of Technology, Germany, now the Technical University Munich--- in 1966. After three years as an assistant professor of CS at Stanford, we left because Stanford didn't have any weather. I joined Cornell's CS Department and have been here ever since, except for a two-year stint at the University of Georgia.

I was chair of CS (1982-1988) and served as associate dean of engineering for undergrad programs (2003-2011). I was also Chair of the Computing Research Board in the late 1980s, spearheading its morph into the CRA (Computing Research Association) ---opening an office in Washington and beginning to actively represent the research and education interests of CS there.

My main research interests over the years have been in compiler writing, programming methodology, teaching programming, and related subjects. Bringing research advances in programming methodology to the undergrad level has been a particular pursuit of mine, and I am proud to have been among the first ten Weiss Presidential Fellows at Cornell.

I've had 20 PhD students. The PhD. Thesis of T.V. Raman won the international ACM Dissertation Award in 1994.

I've been active in editorial duties. For example, after about 40 years as editor and (later) managing co-editor of IPL (Information Processing Letters), I was given the title of Honorary Editor-in-Chief. I have been been editor of the Springer Verlag Series on Texts and Monographs in Computer Science since 1973.
