By the nineteenth century, Jannon's matrices had come to be known as the "Caractères de l'Université" (Characters of the University). It has sometimes been claimed that this term was an official name designated for the Jannon type by Cardinal Richelieu, while Warde in 1926 more plausibly suggested it might be a garbled recollection of Jannon's work with the Sedan Academy, which operated much like a university despite not using the name. Carter in the 1970s followed this conclusion. Mosley, however, concludes that no report of the term (or much use of Jannon's matrices at all) exists before the nineteenth century, and it may originate from a generic term of the eighteenth century simply meaning older or more conservative typeface designs, perhaps those preferred in academic publishing.
