Nancy Stock-Allen’s book is an unapologetic homage (“Her brief but brilliant career in type design” is the subtitle) to the work of type designer Carol Twombly, whose career bridged the critical moment that typography moved from cold type (photo-based creation and capture that never successfully found its legs) to digital. Adobe Systems, where Twombly worked, was the epicenter of early type development for the digital age. At the time of her entry into professional life, Twombly was one of the very few visible women working in type design.
