“The Berthold Foundry [at the turn of the twentieth-century] designed a family of ten sans serifs that were variations on one original font. This Akzidenz Grotesk (called Standard in the United States) type family had a major influence on twentieth-century typography. In addition to . . . four weights . . . Berthold released three expanded and three condensed verions. Akzidenz Grotesk permitted compositors to achieve contrast and emphasis within one family of typefaces. It was a major step in the evolution of the unified and systematized type family.”
