Professeur Yinsen

Professeur Yinsen is the French-language edition of Ho Yinsen, the brilliant physicist who helped a captive Tony Stark build the original Iron Man armor, sacrificing himself so Stark could escape — making him the unsung architect of Iron Man's heroic existence.

A figure of quiet but undeniable significance, Professeur Yinsen made his Bronze Age entrance in 1980 under the Arédit-Artima banner, brought to life by the legendary trio of Stan Lee, Larry Lieber, and Don Heck. Appearing across French-language Iron Man publications, he keeps remarkable company — sharing pages with Tony Stark, Iron Man himself, Jim Rhodes, and even Le Surfer d'Argent. With a presence spanning an impressive four decades in the catalog through 2023, Professeur Yinsen may be a rare find in terms of appearance count, but the caliber of the stories and characters surrounding him makes every one of those issues worth seeking out.
