亡くなる is the polite/respectful verb for 'die' (lit. 'become absent'), used of humans — distinct from the blunt 死ぬ which can sound harsh when speaking of real people. 博士 ('doctor, PhD') as a title suffix marks academic or learned standing. Noguchi died of yellow fever in Ghana while researching the disease he was trying to cure.
