The other key working relationship Gill established while at Capel-y-ffin was with Stanley Morison, the Typographic Advisor to the Monotype Corporation. Morison persuaded Gill to apply the skills and knowledge he had gained in letter cutting to fonts suitable for mechanical reproduction. It was at Capel that Gill designed the typefaces Perpetua (1925), Gill Sans (1927 onwards) and began work on Solus (1929). Gill Sans is considered one of the most successful typefaces ever designed and remains in widespread use.
