Vadim Nikolaevich Delaunay was a Russian poet and dissident, who participated in the 1968 Red Square demonstration of protest against military suppression of the Prague Spring. Delaunay was born to a Russian-French family of Soviet Intelligentsia. His grandfather, Boris Delaunay, was a prominent Soviet mathematician and creator of the Delaunay triangulation. Among his ancestors was marquis Bernard-René de Launay, the last governor of the Bastille, murdered by the attackers on that castle. Delaunay often predicted that he would repeat the fate of his ancestor.
