Whose eighteenth century choice of sign is the reason conventional current points the way positive charge would flow?

1. The sign convention for charge was settled in the 1700s, before the electron was known. 2. Benjamin Franklin, an American politician and scientist, named the charge carried by electrons negative. 3. That naming left conventional current pointing the way positive charge would move. 4. Ampere gave his name to the unit of current and Ohm to the law relating current and voltage, but neither fixed the sign. 5. Edison worked on power distribution a century later, so he is chronologically impossible here. _Source: OpenStax College Physics (CC BY 4.0), Ch 20 "Electric Current, Resistance, and Ohm's Law", section 20.1 Current_
