Biography
Yinsen was held hostage alongside Tony Stark by the Mandarin, who wanted them to build an invincible armor for him. They complied, but decided to have Tony wear the armor to make them escape, and made a dummy in his likeness to keep his identity secret. Tony was unable to save Yinsen from the blast of one of the Mandarin's rings and had to escape alone.
