Professor
Professor Wolverine Vol.1 #48-50,63,176
The man known only as the Professor was in charge of the Eapon X project that laced Wolverine's bones with adamtium. As weapon X, Logan cut the Professor's hand off and escaped the Facility. Years Later, Wolverine tracked down the professor at the US Department of Agriculture in the Pest Control Division. This division is a cover for the covert department that formerly ran the Weapon X project.
