Jean Jannon (1580 – 20 December 1658)[1] was a French Protestant printer, type designer, punchcutter and typefounder active in Sedan in the seventeenth century.
[2] Jannon may have left Paris due to lack of work there or personal conflicts: his friend at the time, diarist Pierre de L'Estoile, recorded in his diary that he met with disapproval with Huguenot authorities for taking on the job of printing a piece of Catholic propaganda.
According to d'Estoile the response of formal approbation from local Huguenot authorities "upset him badly", and he commented that they would be worse than Jesuits if given the chance.
A report from the Council of the Reformed Church of Mainz confirming that the remarriage was acceptable described as her former husband's conduct as a proven series of "adulteries, polygamies and debaucheries".
It was reported to been taken over by Langlois in Paris, although Abraham van Dijck in the 1670s said he intended to buy matrices from Sedan so (if his information was not out of date) some materials might have remained there.
Jannon wrote in his 1621 specimen that: Seeing that for some time many persons have had to do with the art [of printing] who have greatly lowered it…the desire came upon me to try if I might imitate, after some fashion, some one among those who honourably busied themselves with the art, [men whose deaths] I hear regretted every day [Jannon mentions some eminent printers of the previous century]…and inasmuch as I could not accomplish this design for lack of types which I needed…[some typefounders] would not, and others could not furnish me with what I lacked [so] I resolved, about six years ago, to turn my hand in good earnest to the making of punches, matrices and moulds for all sorts of characters, for the accommodation both of the public and of myself.
Some differences in the roman are his characteristic 'a' with a curved bowl and the top left serifs of letters such as 'm' and 'p', with a distinctive scooped-out form.
Opinions on the aesthetic quality of his type has varied: Warde thought it "so technically brilliant as to be decadent...of slight value as a book face", H. D. L. Vervliet described it as "famous not so much for the quality of the design but as for the long-term confusion it created" and Hugh Williamson considered his type to lack the "perfection of clarity and grace" of the sixteenth century, although many reproductions of his work were certainly popular in printing in the twentieth century.
Doubt began to be raised by historian Jean Paillard in 1914, but he died in the First World War soon after publishing his conclusions and his work remained little-read.
The mistake was finally disproved in 1926 by Beatrice Warde (writing under the pseudonym of "Paul Beaujon"), based on the work of Paillard and her discovery of material printed by Jannon himself in London and Paris libraries.
