Johannes Robert Rydberg (1854-1919). Swedish physicist. Rydberg s major contribution to physics was his study of the line spectra of many elements.

Bohr s theory was received with a certain amount of scepticism by Rutherford, but it did have the advantage of explaining various features of atomic spectra. There had been numerous attempts to rationalise the lines observed in atomic emission spectra since the invention of the spectroscope by Bunsen and Kirchhoff in 1859 (Chapter 9). Little progress was made until 1885 when Johann Jacob Balmer (1825-1898), a Swiss school teacher, showed that the wavelengths of the four lines then known in the hydrogen spectrum could be expressed in terms of a simple equation. In 1890 Balmer s formula was rearranged by Johannes Robert Rydberg (1854-1919) to the form... 

Named for Johannes Robert Rydberg, who discovered this empirical relation in 1890 after a study of a large mass of data. 

Johannes Robert Rydberg, 1854-1919, was professor of physics at the University of Lund in Sweden, where he received both his bacheior s and doctor s degrees in mathematics and where he spent his entire career. He was originally an instructor in mathematics but moved into mathematical physics.
