David Martinez (Associate Professor in both the Classics and Divinity departments at the University of Chicago), one of Francis Gignac’s students a long time ago, once told me that Gignac was far and away the best Hellenistic Greek grammarian alive today. All of us waited for the third volume, Syntax, of his projected trilogy on Roman and Byzantine Greek (volumes 1 and 2 were on Phonology and Morphology, respectively). But the third volume never was published. Perhaps an alumnus of Catholic University of America could locate his files, edit the volume, and publish it for Gignac posthumously.
My friend and former intern, Chris Skinner, recently blogged about the passing of Father Francis Gignac earlier this month. Here’s the link: http://cruxsolablog.com/2014/06/04/francis-t-gignac-s-j-1933-2014-skinner/
