Robert-Alain de Beaugrande (1946 – June 2008) was a text linguist and discourse analyst, one of the leading figures of the Continental tradition in the discipline. He was one of the developers of the Vienna School of Textlinguistik (Department of Linguistics at the University of Vienna), and published the seminal Introduction to Text Linguistics in 1981, with Wolfgang U. Dressler. He was also a major figure in the consolidation of critical discourse analysis.
As a graduate assistant, I taught from this text at UF. The examples came from actual student essays. Very useful exercises that contributed to organic--not formulaic--college-level discourse. A down-to-earth rhetoric handbook by a brilliant professor (I was enrolled in his Teaching College English Practicum that term). He is sorely missed in the linguistic community of scholars.
