Stereoscopy Day is an international celebration of the birth of stereoscopic 3-D.
Founded by the Brian May Archive of Stereoscopy, it celebrates:
- The inventor of stereoscopy, British polymath Sir Charles Wheatstone.
- Stereoscopy’s pioneers and their successors, up to the present day.
- The long history of the medium, from its first Golden Age and subsequent periods of popularity.
- Its rich diversity and multiple uses in various fields.
- The sheer immersive magic it can bring to images, and other applications.

Stereoscopy Day is celebrated across the world every year on June 21st, which is the anniversary of the day in 1838 when Sir Charles Wheatstone officially presented his revolutionary reflecting stereoscope to the Royal Society of London, and demonstrated his theory of binocular vision.

A more portable version of the stereoscope was later popularised by Sir David Brewster in the early 1850s.

The idea of Stereoscopy Day was sparked on the official 180th birthday of stereoscopy, June 21st 2018, at King’s College London, with the talk “Professor Wheatstone, the inventor of the Stereoscope, was also there“.
Sir Charles Wheatstone was the first appointed Professor of Experimental Philosophy at King’s College London, and the University holds the Wheatstone Collection.
