An independent scientist (historically also known as gentleman scientist) is a financially independent scientist who pursues scientific study without direct affiliation to a public institution such as a university or government-run research and development body.
The term "gentleman scientist" arose in post-Renaissance Europe,[1] but became less common in the 20th century as government and private funding increased.
Most independent scientists have at some point in their career been affiliated with some academic institution, such as Charles Darwin, who was affiliated with the Geological Society of London.
