Eric Gill is far from an example of an ideal parent, but I enjoyed this note (at on ‘Joanna’, the typeface he designed in 1930, released by the Monotype Corporation in 1937:

He created the typeface for the printing firm of Hague & Gill, which he formed to give his idle son-in-law an occupation, and named the design for his daughter. Only the Caslon foundry cut it for hand composition. It is, as Gill himself described it, “a book face free from all fancy business,” with small, straight serifs and a spare elegance that makes it notably attractive and distinguished.
