William Hyde Wollaston (1766-1828) was an English scientist whose work ranged across chemistry, optics, and physics. In 1802 he observed dark lines in the solar spectrum, an important early step in the history of spectroscopy.
Solar spectrum
Wollaston observed dark lines in sunlight using a prism and a narrow slit. He interpreted them as boundaries between colors rather than as absorption features. Joseph von Fraunhofer later mapped many more of these lines with greater precision, and they became known as Fraunhofer lines.
Although Wollaston's observation came before quantum mechanics, spectral lines later became central evidence for discrete atomic energy levels and quantum transitions.
