Trivia: Symbol & Electron Flow

Today, I learn who caused the 'mess' on current flow & symbol confusion. At last.

Benjamin Franklin, that's who.

As shown in the diagram, actual current or electron flow is counter-clockwise. But because of earlier (naive) assumption by Ben, current symbol standard (diode, for example) follows the wrong flow.

But this is trivial, really. Conventional wisdom still works.
