Senior managing editor and logophile Andy Hollandbeck reveals the sometimes surprising roots of common English words and phrases. Remember: Etymology tells us where a word comes from, but not what it means today.
The kaleidoscope is, for the most part, a fun little visual toy that elicits awe in children and adults alike. Though it may seem like “just” a trick of light, dark, and mirrors, it is the result of some serious 19th-century scientific study.
The first kaleidoscope was developed by Scottish physicist Sir David Brewster. His work in optics was so fundamental that some people call him the Father of Modern Experimental Optics. He created his first kaleidoscope around 1817, a year after he was elected to the Royal Society. He illustrated the specifics of his little contraption first in 1819’s “A Treatise on the Kaleidoscope” and then later in The Kaleidoscope: Its History, Theory, and Construction, published in 1858.
The name kaleidoscope was one Brewster coined himself — if only because he needed a name for the patent application. He must have been quite taken with the images he saw in his contraption because the word he constructed from Greek roots means “an instrument for seeing beautiful shapes”: kalos “beautiful” + eidos “shape” + skopos “watcher.”
He was granted his patent, and the kaleidoscope did become quite popular, though Brewster made little money from it, in part, no doubt, from the fact that his specifications had been made public as scientific knowledge — and were therefore easily pirated.
Apparently, Lord Byron even enjoyed a kaleidoscope, having received one as a gift from, probably, his publisher. In the second canto of Don Juan (stanza 93), written in the winter of 1818-1819 — even before Brewster’s “Treatise” hit the scene — we find this reaction to the sight of a rainbow among a group of adrift sailors:
Our shipwrecked seamen thought it a good omen —
It is as well to think so, now and then,
’Twas an old custom of the Greek and Roman,
And may become of great advantage when
Folks are discouraged; and most surely no men
Had a greater need to nerve themselves again
Than these, and so this rainbow looked like Hope —
Quite a celestial Kaleidoscope.
The kaleidoscope was barely a year old, and already the wordsmiths were using the name metaphorically to describe not the physical object but an analogue to the colorful, awe-inspiring images one might see inside it.
