Etymology

Origin of daguerreotype

1830–40; named after L. J. M. Daguerre; see -o-, -type

Explanation

An old-fashioned black-and-white photograph with a shiny, almost mirror-like surface is a daguerreotype. The daguerreotype was named for its inventor, Louis Daguerre, known as one of the fathers of photography. Daguerre's 1837 process involved using a sheet of copper that was coated with a thin layer of silver and needed just 20 minutes of exposure; it replaced an earlier method that required eight hours to produce an image. Less expensive types of photography made the daguerreotype obsolete within 20 years, and today they're extremely rare.

Example Sentences

Daguerreotype images of models were already being used by artists in the 1840s.
