Here's a little quiz for you.
Take your favorite works of translated fiction. Now, name their translators. How many do you know by name? I would venture to guess, "Not very many, if any at all."
This would be especially true for works translated into English. Some authors who are born with English as their native language even nurture a mild bias against translators, thinking that "Those who do, write; those who don't, translate." In the English-speaking world, the translator is sometimes so little regarded as to not even have their name placed on the book's cover.
