Berlin-based Dutch type designer Luc(as) de Groot is mostly known for his large font family Thesis: TheSans, TheSerif, TheMix, TheSansMono and TheAntiqua. He designed Corpid and custom fonts for magazines such as TAZ for die tageszeitung and SpiegelSans for Der Spiegel in Germany, FolhaSerif for the Brazilian newspaper Folha de S.Paulo, plus others for Le Monde, Metro, and German TV station ARD. He created corporate type for international companies including Sun Microsystems, Bell South, Heineken, Siemens and Miele. For Microsoft he designed the monospaced font family Consolas, and Calibri, the new standard typeface in Microsoft Word.
Luc(as) de Groot is a web font and hinting specialist and developed a theory of interpolation. He runs his type foundry LucasFonts
and design bureau FontFabrik in Berlin, and teaches at the University of Applied Sciences in Potsdam, Germany.
Luc(as) likes to introduce a new terminology named "readability per square centimetre" and explains that it often works contrary to our expectations. The readability per square cm does not depend on font choice in the first place, but on many other factors, that also play an important role in the web.
