Lucas de Groot

De Groot was born in the Netherlands and studied at the Royal Academy of Arts in The Hague. He adopted the name Luc(as) on his business card after graduating as a reference to people calling him by both "Luc" and "Lucas". After having worked for a few years at Amsterdam-based design agency BRS Premsela Vonk (since 2009 called Edenspiekermann), De Groot moved to Berlin to work at MetaDesign under Erik Spiekermann. Some of his early work included alternative versions of Frutiger, which much of his work is influenced by. While working at MetaDesign he began working on the Thesis family in his spare time, a project he described as being enabled by a lack of personal connections outside work. Thesis was initially published by Spiekermann's FontShop library before he established an independent company.

De Groot's work includes commercially released fonts and also custom families for particular clients: Corpid (previously AgroSans) for the Dutch Ministry of Agriculture; SunSans for Sun Microsystems; SpiegelSans and Taz for, respectively, the German magazines Der Spiegel and die tageszeitung; and FolhSerif for the Brazilian newspaper Folha. Some of these such as Taz have since become publicly available.

De Groot teaches at the Design Faculty of the Fachhochschule Potsdam or University of Applied Sciences in Potsdam, outside Berlin.
