Charles Masson (1800–1853) was the pseudonym of James Lewis, a British East India Company soldier, independent explorer and pioneering archaeologist and numismatist. He was the first European to discover the ruins of Harappa near Sahiwal in Punjab, now in Pakistan. He found the ancient city of Alexandria in the Caucasus dating to Alexander the Great. He unlocked the now-extinct language known as Kharoshthi.
