Wallace Fujikawa

Doctor Wallace Fujikawa, along with Doctor Tobias Fleming Shaw, was the co-creator of the Shaw-Fujikawa Translight Engine in 2291, the first device that allowed humanity to reach beyond their solar system. Little else is known about the man.

Trivia
In a recent Bungie update, there is a shrine devoted to Fujikaw and Shaw on Moonbase Alpha, making it plausible it is a UNSC Research Facility.
