callous from Late Middle English:
The Latin source callosus means ‘hard-skinned’, and the word was originally used in this sense. The transference to ‘insensitive to others’ feelings', which happened in the late 17th century, has a parallel in thick-skinned. Callus (mid 16th century), for hardened skin, is from the same word.
