Johann Jakob Balmer Born: 1 May 1825 in Lausanne, Basel-Land, Switzerland Died: 12 March 1898 in Basel, Switzerland 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 became 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.

12. Johann Jacob Balmer Johann Jacob Balmer (18251898). Note on the Spectral Lines of Hydrogen.Annalen der Physik und Chemie 25, 80-5 (1885) as translated and published by Henry http://web.lemoyne.edu/~giunta/balmer.html

Johann Jacob Balmer (1825-1898) Note on the Spectral Lines of Hydrogen 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.

Johann Jacob Balmer Atomic Spectra (Johann Jacob Balmer) After chemists and physicists began using the spectroscope to catalog the wavelengths of the light either emitted or absorbed by a variety of compounds, these data were then used to detect the presence of certain elements in everything from mineral water to sunlight. No obvious patterns were discovered in these data, however, until 1885 when Johann Jacob Balmer analyzed the spectrum of hydrogen. When an electric current is passed through a glass tube that contains hydrogen gas at low pressure the tube gives off blue light. When this light is passed through a prism as shown below, four narrow bands of bright light are observed against a black background. These narrow bands have the characteristic wavelengths and colors shown in the table below. Balmer noticed that these data fit the following equation to within ±0.02%. In this equation, R H is a constant known as the Rydberg constant, which is equal to 1.09678 x 10 nm , and n is an integer between 3 and 6. The Characteristic Lines in the Visible Spectrum of Hydrogen Wavelength (nm) Color red blue blue-violet violet The blue light given off when a tube filled with H gas is excited with an electric discharge can be separated into four narrow bands of light when it is passed through a prism.
