A memory disk in Matsumoto's file boxes revealed a lighter side of the good doctor.
CORRECTION, This is Dr. Matsumoto’s son, which explains the 2013 record date. He was doing signing for the deaf.
We have no permission to publish media of his younger brother so this video has been removed.
I am starting to get Bob withdrawals. lol
Hard to know what story he is telling, some kind of repeat gestures point to a sign language, but his control of facial expressions is fun to watch and show his human side in full. Perhaps he was trying to explain his Electronuclear theory in hand sign language? Who knows! But thanks for sharing this humanizing aspect of Dr. Matsumoto with the world!
