Mark Simonson is an independent type designer working out of his home in Saint Paul, Minnesota.
Although he got interested in designing typefaces while studying commercial art in college during the seventies, Mark spent the first few decades of his professional life as a graphic designer and magazine art director.
In his spare time, he dreamed up ideas for typefaces and read everything he could find related to type design. Thanks to the availability of desktop font-making software, he was finally able to get a few fonts published in the mid-nineties. By 2005, he had over a dozen font families on the market and was doing type design full time.
He is probably best known for designing the popular typeface Proxima Nova.
