An essay in the form of a letter, expanded and edited for publication, from William Addison Dwiggins to Rudolph Ruzicka on the subject of typeface design. It is especially interesting because it explains Dwiggins' own process and goes slightly beyond abstract "design" and outlines the interactions between Dwiggins and the type development organization at Mergenthaler Linotype. "G," mentioned in the text, is Chauncey H. Griffith, typeface designer in his own right, but also the vice president in charge of typeface development at the Mergenthaler Linotype Company.
