Looks like that MJMNTBCNFUTMJXDJGIBEABNQJIIWHRBLFO9DLJVFOC99FXZGMX9LSSUTJTRWFUSCJ9W9ATSRERPKRAA N9 is his current address in the snapshot. I have derived this from https://bitcointalk.org/index.php?topic=1360660.msg14259388#msg14259388. It contains 1'073'963'526'373 iotas now, not sure if they were claimed, I'll check it later.
