Jan Tschichold was a powerful influence on the world of typography. Tschichold was raised in Germany and began working in typography very young.
The Nazi’s seized most of his work as they deemed it a threat to Germany’s culture. After he fled the country he wrote Die Neue Typographie and condemned all fonts that weren’t sans-serif.
While working for Penguin Books he created a standardized practice for all of their book covers. Later in his life he reversed his book and advocated for roman typefaces and blocks of copy.
