a founding editor of the Journal of Geometric Analysis.For 30 years, he worked hard to attract good papers and to set a standard of excellence for the journal.Our success today is due in no small part to Sibony's efforts.Nessim Sibony was an outstanding mathematician with many profound insights into the complex analysis of several variables.Even his Ph.D. thesis has been strongly influential.Over the years, Nessim has produced a number of important counterexamples that have really charted new directions in the field.On a personal level, Nessim Sibony was warm and friendly.A real gentleman in all circumstances, his friendship and collegiality will certainly be missed.
