Phil Martin, creator of over 400 typefaces from the late '60s through the '80s, designed Grad as a redesign of the classic Century Schoolbook for his personal use in the early '90s. He made both subtle and obvious changes and added many new features such as small caps, old style figures, ligatures, and swash capitals. For ten years, Grad was trapped inside Phil's old DOS computer in an obsolete format. Working from laser prints provided by Phil and specimens of the original ATF Century Schoolbook, Mark Simonson has brought it into the 21st century as a family of three feature-rich OpenType fonts.
