Encyclopedia > Johann Balmer

Johann Jakob Balmer (May 1, 1825 – March 12, 1898) was a Swiss mathematician.


He was born in Lausen, Switzerland.


Despite being a mathematician, he is not remembered for any work in that field; rather, his major contribution (made at the age of sixty) was an empirical formula for the spectral lines of the hydrogen atom. A full explanation of why the formula worked had to wait until the work of Niels Bohr.


Balmer lines and Balmer series are named after him.


A crater on the Moon is named after him.
