	Balmer, Johann Jakob
		Johann was the eldest of his parents sons.
		However, despite being a mathematics teacher and lecturer all his life, Balmer is best remembered for his work on spectral series and his formula, given in 1885, for the wavelengths of the spectral lines of the hydrogen atom.
		It is surprising to realise that Balmer was sixty years old when he wrote the paper for which he is famous on the spectral lines of the hydrogen atom and that he was seventy-two when he wrote his only other work on this topic.

	Johann Jakob Balmer
		Johann Jakob Balmer (May 1 1825 – March 12 1898) was a Swiss mathematician and an honorary physicist.
		Balmer then used this formula to predict the wavelength for m = 7, and a colleague at the university was able to confirm a match to a high degree of accuracy.
		Balmer crater on the Moon is named after him.

		Johann Balmer's doctorate from Basel was for a dissertation on the cycloid.
		He taught in Basel all his life both as a school teacher and as a university lecturer at the University of Basel.
		However Balmer is best remembered for his work on spectral series and his formula, given in 1885, for the wavelengths of the spectral lines of the hydrogen atom.

	Referaty.sk - Spectroscopy (Johann Jakob Balmer)
		Balmer, Johann Jakob (1825-1898), Swiss mathematician and physicist, born in Lausanne, Switzerland.
		In 1885 Balmer discovered a simple mathematical formula that generated the wavelength values for a certain series of spectral lines of the element hydrogen.
		The reason that Balmer's formula generated the correct wavelength values was not understood until the development of quantum theory in the early 1900s.

		A Swiss schoolteacher named Johann Jakob Balmer measured the wavelengths, and developed a formula that predicted the wavelength of the lines accurately.
		This formula had in it the value of the charge of the electron, the mass of the electron, a key number called Planck’s constant, and some πs and 2s.
		When worked out, Bohr’s picture of the atom gave exactly the same wavelengths of light as Balmer’s measurement.
