Israeli-American mathematician who has made important contributions to the fields of hypergeometric summation and
q-Series. 
The so-called Wilf-Zeilberger pair and
Zeilberger's algorithm are indispensable tools for summing hypergeometric series, and these
techniques are used extensively in modern computer algebra software. Zeilberger was also the first to prove the elusive
result in combinatorial theory known as the alternating sign matrix conjecture, as well as a number of
related propositions. Zeilberger was a co-recipient of the 1998 Steele Prize of the American Mathematical Society for
his research on hypergeometric summation.
