“It was chiefly as a text designer that [Hans] Schmoller made his mark [at Penguin Books]. . . . It was a design based on sound principles and well-tried practices, although Schmoller, like [Jan] Tschichold before him, had to repeat the same insistent instructions about “optically even letterspacing” time after time. Schmoller gained a reputation for his fastidiousness and ability to notice minute variation of detail. He earned the nickname Half-Point Schmoller, ‘The only man who could distinguish between a Bembo full point and a Garamond full point at 200 paces’.”

—Phil Baines, from Penguin by Design: A Cover Story 1935-2005, 2005.
