Peter Desaga
Peter Desaga was a German instrument maker at the University of Heidelberg who worked with Robert Wilhelm Bunsen. In 1855, Desaga perfected an earlier design of the laboratory burner by Michael Faraday into the Bunsen burner. The Desaga family held the right to market the burner for generations, as part of an agreement made with Bunsen. The Bunsen burner was essential to the invention of the spectroscope by Robert Wilhelm Bunsen and Gustav Robert Georg Kirchhoff.
Peter Desaga's son, Carl Desaga, founded C. Desaga.
