Early optical experiments

Publication of Magia Naturalis

1558

The first publication of Giambattista della Porta's Magia Naturalis recorded ideas about optical phenomena that included multiple reflection.

Giambattista della Porta describes reflection

1558 - 1589

Giambattista della Porta described multiple reflection by two or more reflecting surfaces in his work Magia Naturalis, published across editions from 1558 to 1589.

Adjustable mirror angles demonstrated

1646

Kircher's two-mirror construction could be positioned at various angles, demonstrating how changing mirror geometry altered reflected images.

Athanasius Kircher's mirror experiment

1646

In 1646, Athanasius Kircher described a construction using two mirrors that could be opened and closed like a book.

Reflected polygon figures observed

1646

Kircher reported regular polygon figures made from reflected aliquot sectors of 360 degrees in his mirror experiment.

Richard Bradley publishes a related construction

1717

Richard Bradley's New Improvements in Planting and Gardening described a construction similar to Kircher's mirror arrangement.

Multiplied reflection used to form images

1717

The construction described by Richard Bradley showed images produced through multiplied reflection, anticipating an important visual principle of the kaleidoscope.

Mirrors applied to geometrical drawings

1717

Bradley's construction was intended to be placed over geometrical drawings so that the drawings appeared multiplied through reflection.

Optimal kaleidoscope configuration remains unrecorded

1717 - 1815

Although earlier mirror experiments existed, an optimal configuration producing the full effects of a kaleidoscope was not recorded before 1815.

Brewster temporarily forgets the effect

1814

After first noticing the relevant optical effect in 1814, Brewster forgot about it before returning to related experiments.

Brewster observes multiplication of sectors

1814

Brewster also noticed the multiplication of sectors formed by the extremities of glass plates.

Circular arrangement of candle images observed

1814

During his 1814 experiments, Brewster first noted a circular arrangement of candle images around a center.

Brewster begins polarization experiments

1814

In 1814, Sir David Brewster conducted experiments on light polarization using successive reflections between plates of glass.

Brewster rediscovers the effect

Feb 1815

During further experiments in February 1815, Brewster noticed a more impressive version of the reflected-image effect.

1815

Following his 1815 experiments, Brewster developed the reflected-pattern device as a new optical instrument.

The kaleidoscope concept takes shape

Feb 1815

Brewster's more impressive 1815 observation established the essential optical effect that would be developed into the kaleidoscope.

Patent application for the kaleidoscope

1817

Brewster's invention was submitted for protection as a new optical instrument called the kaleidoscope.

Patent number 4136 granted

Jul 1817

Patent 4136, for a new optical instrument called the Kaleidoscope, was granted in July 1817.

Patent emphasizes ornamental arts

Jul 10, 1817

The kaleidoscope was first published in the patent granted on July 10, 1817.

Manufacturing and popularization

Brewster permits other manufacturers

1818

To address the extraordinary demand, Brewster gained permission from Carpenter in 1818 for other manufacturers to make the device.

Kaleidoscope production expands

1818

Permission for additional manufacturers to produce kaleidoscopes broadened the device's manufacturing base.

Demand exceeds the company's capacity

1818

In 1818, demand for the kaleidoscope exceeded the level that the company associated with its production could meet.

Brewster publishes Treatise on the Kaleidoscope

1819

Brewster's 1819 Treatise on the Kaleidoscope documented the instrument and its commercial development.

Manufacturers listed in the Treatise

1819

In his 1819 Treatise on the Kaleidoscope, Brewster listed more than a dozen manufacturers and sellers of patent kaleidoscopes.

Modern culture and collecting

Brewster Kaleidoscope Society founded

1970 - 2001

Key Facts

  1. Scottish scientist Sir David Brewster invented the kaleidoscope in 1816 and patented it in 1817.
  2. The name comes from Greek words meaning “beautiful form watcher.”
  3. Kaleidoscopes use mirrors and colorful objects to produce repeated symmetrical patterns through reflection.
  4. The device became popular in the nineteenth century as both a scientific instrument and a decorative novelty.
  5. Modern kaleidoscopes are valued as educational tools, artistic objects, and examples of optical geometry and symmetry.
