Geoffrey Chaucer (c. 1343 - 25 October 1400) was an English author, poet, philosopher, bureaucrat, courtier and diplomat. Although he wrote many works, he is best remembered for his unfinished frame narrative The Canterbury Tales. Chaucer is credited by some scholars as being the first author to demonstrate the artistic legitimacy of the vernacular English language.
In an alternate where the Great Black Deaths wiped out most of Europe, Geoffrey Chaucer was killed by the epidemic before he could write The Canterbury Tales, although he did write other things. He died at some point before 1372. Annette Klein noted that the language spoken in the England of this timeline was closer to Chaucer's than the English of the home timeline.[1]
