He shows up in the Century Dictionary's sixth definition for indicator, which reads as follows: "In a microscope, an arrangement for marking the position of a particular object in the field of view. Quekett's indicator was a steel finger connected with the eyepiece."

Here's what the Wikipedia page about him has to say: "When only sixteen John gave a course of lectures on microscopic subjects, illustrated by original diagrams and by a microscope which he had himself made out of a roasting-jack, a parasol, and a few pieces of brass purchased at a neighbouring marine-store shop."
