American Express is credited with inventing the traveler's check

In the 1890s, then American Express President James C. Fargo was frustrated that he couldn't get cash while traveling in Europe outside of major cities. Marcellus Berry, an American Express employee, came up with the idea of a traveler's "cheque": a prepaid check, similar to cash, that requires the signature of both the customer and the receiving institution to be valid. American Express never modernized the spelling of the word "cheque" and stopped providing them at the end of 2020.
