   Extractions: Johann Balmer 's father was also named Johann Jakob Balmer and he was a Chief Justice. Johann's mother was Elizabeth Rolle Balmer. Johann was the eldest of his parents sons. He attended his first school in Liestal, a town which had just become the capital of the half canton of Basel-Landschaft. Then, for his secondary education, he studied at a school in Basel where he excelled in mathematics and decided to study that topic at university. For his university studies in mathematics Balmer attended the University of Karlsruhe and the University of Berlin. His course of studies led to a doctorate which he received from the University of Basel in 1849 for a dissertation on the cycloid. Balmer taught in Basel all his life. From 1859 until his death in 1898 he was a school teacher of mathematics at a secondary school for girls in the city. From 1865 until 1890 he was also a university lecturer in mathematics at the University of Basel where his main field of interest was geometry. He married Christine Pauline Rinck in 1868 when he was 43 years old and they had six children. 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. This was set out in one of only two papers which he wrote on spectra of the elements, the second being in 1897. 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. But for his work on what amounts to a problem in physics, Balmer would be unknown today within the history of mathematics since he made no contribution to geometry of special significance despite it being the topic of interest throughout his life.

   Extractions: Annalen der Physik und Chemie The World of the Atom, Vol. 1 (New York: Basic Books, 1966) with omissions filled in by Carmen Giunta] We may call this number the fundamental number of hydrogen; and if corresponding fundamental numbers can be found for the spectral lines of other elements, we may accept the hypothesis that relations which can be expressed by some function exist between these fundamental numbers and the corresponding atomic weights. The wavelengths of the first four hydrogen lines are obtained by multiplying the fundamental number h = 3645.6 in succession by the coefficients 9/5; 4/3; 25/21; and 9/8. At first it appears that these four coefficients do not form a regular series; but if we multiply the numerators in the second and the fourth terms by 4 a consistent regularity is evident and the coefficients have for numerators the numbers 3 and for denominators a number that is less by 4. For several reasons it seems to me probable that the four coefficients which have just been given belong to two series, so that the second series includes the terms of the first series; hence I have finally arrived at the present formula for the coefficients in the more general form: m /(m -n ) in which m and n are whole numbers.

    Extractions: This entry contributed by Dana Romero In 1885, Johann Balmer discovered a formula for the series of discrete spectral lines emitted by atomic hydrogen . These had been observed for many years previously, with many unsuccessful attempts to describe them mathematically. The Balmer formula is given by for n = 3, 4, ... (the principal quantum number ), where is the wavelength of the light emitted and R is a constant now known as the Rydberg constant . If is measured in meters, For n = 3, the Balmer formula gives a wavelength is 656.3 nm, which is known as the Hydrogen-alpha line. Since the Balmer formula, other series have been found, most notably the Lyman, Paschen, and Brackett series, each describing different electron transitions of orbiting electrons in the hydrogen atom . Each of these formulas is a special case of the general equation
