“Jos Buivenga has been designing type for nearly twenty years”
Sally Kerrigan, writing for Typekit:
Pleased with the favorable response to his first designs, Jos posted the fonts on his website for free downloading, and continued with his typography hobby on the side of other work. After about a decade of this, and in response to his growing popularity, he opened the exljbris foundry and transitioned into full-time type design.
If you don’t know Jos, you may recognize his typefaces.
