Cristoforo de Predis - The Predis Codex
"Cristoforo de Predis was a deaf early Renaissance illuminator and miniaturist in Milan, Italy. The surname sometimes appears as da Predis or di Predis. His better-known hearing half-brother, Ambrogio de Predis, also a painter, worked with Leonardo da Vinci and reportedly taught Leonardo some of his deaf brother's signs to help make Leonardo's paintings more expressive. Some sources erroneously label Cristoforo as Ambrogio's father, but they were in fact half-brothers. The Predis Codex is a bound collection of Cristoforo's miniature paintings of scenes from the Bible." - quote from here.
