Goudy Open was designed by Frederic Goudy, who was inspired by the caption of a French engraving. It is Goudy's first attempt at a "modern" face, but with less contrast and rigidity normally found in Bodoni style Modern faces.
Goudy Modern was designed later in 1918 after viewing a proof of Goudy Open with the line filled in. Not a true "modern" face, but still a Goudy classic. The Pro versions include ligatures, varieties of numerals and Central European character sets.
