In 1814 the young Dane Rasmus Christian Rask submitted an entry to an essay contest on Icelandic history, in which he concluded that the Germanic languages were (as we would put it) in the same language family as Greek, Latin, Slavic, and Lithuanian. He was in doubt about Old Irish, eventually concluding that it did not belong with the others (he later changed his mind), and further decided that Finnish and Hungarian were related but in a different family, and that "Greenlandic" (Kalaallisut) represented yet a third. He was unfamiliar with Sanskrit at the time. Later, however, he learned Sanskrit, and published some of the earliest Western work on ancient Iranian languages.
