A number of German writers intentionally suppressed the letter ‘r’ (as did also a fair number of Italians), of whom the eighteenth-century German poet Gottlob Burmann (1737-1805) is perhaps the most amusing: he is reported to have hated the letter ‘r’ to such an extent that in 130 poems he never used it and refused to pronounce his own last name.
