The first spectroscope was invented in 1814 by the physicist and lens manufacturer Joseph von Fraunhofer. In 1859, German chemist Robert Wilhelm Bunsen and physicist Gustav Robert Kirchhoff used it to identify materials that emit light when heated.

Who founded spectroscopy?

Generally, Sir Isaac Newton is credited with the discovery of spectroscopy, but his work wouldn't have been possible without the discoveries made by others before him.

Where was the spectroscope used?

Spectroscopes are often used in astronomy and some branches of chemistry. Early spectroscopes were simply prisms with graduations marking wavelengths of light. Modern spectroscopes generally use a diffraction grating, a movable slit, and some kind of photodetector, all automated and controlled by a computer.
