The Typewriter Control Post: Glenn's Masterpiece

 


If there is one element that defines a McElroy figure above all others, it's the control post.

Most ventriloquist figures of the 1930s and 40s were operated with a simple wooden stick and one or two levers for the jaw and maybe the eyes. The McElroy control post is something else entirely.

Glenn McElroy designed a system of typewriter-style keys and levers mounted on a box at the top of the headstick. Each key or lever controls a specific animation: one for the left winker, one for the right, one for the eyebrows, one for the tongue, one for the nose. The jaw is controlled by the thumb. The upper lip by the index finger on the other side.

The result looks like a tiny musical instrument. And in a way, that's exactly what it is — a instrument for playing expressions.

What fascinates me most is that Glenn designed this system to be operated with one hand, while the other hand is free for gestures or props. Every control is positioned so that the performer can reach it naturally, without looking, without thinking.

That's not just engineering. That's ergonomics. That's craft at the highest level.

Replicating this system is one of the greatest challenges — and greatest joys — of building a McElroy replica.
