1916


TimFox:
The 1916 ad shows two kinds of clips, but neither is an "alligator clip".
Cyberdragon:
The crocodile clip or alligator clip was invented in 1908 by Ralph Mueller.

TimFox:
In careful usage, the "alligator clip" has upper and lower jaws that meet, while in the "crocodile clip" the upper jaws go inside the lower jaws.
My original "anachronism" comment referred to the modern cheap alligator-clip test leads in the photo that are ubiquitous now.

When I was at UCL they got some of Fleming's original experimental thermionic diodes out of storage, and used modern parts to make a simple radio from one of them. It was some anniversary event. Those valves looked like they have been produced by an expert glass blower.
