Rudolf Koch's and Fritz Kredel's remarkable Blumenbuch [the flower book] was published several times between 1929 and 1942, from pocket book editions to precious volumes and portfolios, involving many collaborators, printers and publishers like Mainzer Presse, Ernst-Ludwig-Presse in Darmstadt and Insel-Verlag, Leipzig. The essay by Jérôme Knebusch compiles a detailed chronology of the different editions and presents rare and unpublished material from the archives of the Klingspor Museum, Offenbach am Main. About the Blumenbuch is the first of the Poem Pamphlet series edited by Alice Savoie and Jérôme Knebusch.

Alice Savoie and Jérôme Knebusch have edited between 2020 and 2025 ten essays by Jérôme Knebusch, Sébastien Morlighem, Riccardo Olocco, Dan Reynolds, Éloïsa Pérez, EESAB Type, Yoann De Roeck, François Chastanet, Julien Van Anholt in the Poem Pamphlets collection. The screenprinted box, white on black paper, assembles them.

In 2011, students of ESAL Metz started within a workshop with Argentinian type designer Alejandro Lo Celso and their teacher Jérôme Knebusch a specific design for their school. Looking for a bookish typeface tending to modern forms, the students found interesting references in the work of Baskerville and Didot, precisely: exactly inbetween. The type grew during the following years, each time in intensive workshop sessions, to a complete type family named Messine, covering text, display, poster, italic, bold, sans and serif versions. Today, Messine is the official and exclusive typeface of the school, used all over its documents.

Of all the title fonts from the Klingspor type foundry, Neuland was probably the most frequently used abroad. But how was it produced? A letter Koch sent to Ernst Kellner in 1922 raises more questions than it answers, and designers have speculated for nearly half a century about whether Koch really cut the hallmarks without any preparation. Dan Reynolds has examined the various sources; Edvinas Žukauskas and Jérôme Knebusch have digitised the different sizes for the first time. The essay Making Neuland and the typeface Koch Grotesk were published by Poem for Neuland’s centenary in 2023. Conference held at ENSAD Nancy, 28 November 2023. It was recorded, link below.
