Here we are counting down the 100 greatest fonts, but you can read interviews with some of the typefaces' creators, a brief history of type, the anatomy of a font, and much, much more in the book – find out how to get your copy in print or digital formats at the foot of this post.

But without further ado, here is the 89th best typeface…

89. Thesis

  • Lucas de Groot, 1994

Renowned typographer Lucas Adrianus Wilhelmus de Groot really wanted to be a painter – but his work had always been focused on graphics. His career in typography started when he was at school in Noordwijkerhout where he became annoyed and frustrated by the bad typography used in the school magazine. He decided he would do something about it, immediately posting his suggestions for improvement under the editor's door. By the following day he was on the editorial team.

From 1982 to 1987, de Groot studied under Gerrit Noordzij at the Royal Academy of Art in The Hague – a hot-bed for new typographers. He specialised in typography, photography and illustration and his final piece of work was produced entirely in typefaces that he had designed himself – among them an early version of what later became his successful Thesis typeface (at that time still called 'Paranthesis').

Between 1989 and 1993, de Groot worked for the respected design agency BRS Premsela Vonk on large corporate design projects. It was here that he laid the foundations for TheMix, Thesis' semi-serif version, which became the corporate font of the Dutch Ministry of Transport and Water Management.

When he came to Germany in 1993 and joined MetaDesign in Berlin, he finally had time to finish Thesis with its three families – TheSans (sans-serif), TheSerif (slab serif), and TheMix (slab serif): "I couldn't speak the language yet and I hardly knew anybody, so I took the time to complete Thesis," he recalls.

By 1994, Thesis had become a bestselling member of the FontFont Library. Despite the popularity of Adobe's multiple-master fonts, which made it possible for ordinary users to generate custom fonts very easily, many type enthusiasts favoured FF Thesis with its 144 fonts. One reason for this was undoubtedly the eight carefully harmonised font weights, which Lucas de Groot had developed with typographic sensitivity on the basis of his own interpolation theory. In addition to this, Thesis' range of characters was unrivalled at that time. It remains a classic type system, with TheSans being particularly versatile with its monospaced, hairline, typewriter and Arabic versions.

An enormous range of characters, with ligatures and variations, makes Thesis a typographical treat for designers

Thesis grew out of a dissatisfaction with the limited range of typefaces available for corporate identity work
