Doyald Young was a master typographer whose beautiful typefaces are rooted in 16th- and 17th-century. As a teacher for 30 years at the Art Center College of Design in Pasadena, he didn't just teach the formal conventions or aesthetic theories of type, but he also based his teaching on the satisfaction found in perfecting the craft.
His books are definitely worth owning if your a designer.
I was so honored to hear Mr. Young speak on several occasions a true legend of design. RIP Mr. Young
