Helmholtz's polyphonic siren, Hunterian Museum, Glasgow. Hermann Ludwig Ferdinand von Helmholtz (/ ˈ h ɛ l m h oʊ l t s /; German: [ˈhɛʁ.man vɔn ˈhɛlmˌhɔlts]; 31 August 1821 – 8 September 1894; "von" since 1883) was a German physicist and physician who made significant contributions in several scientific fields, particularly hydrodynamic stability. [2]
The biography of Helmholtz was published in 1902 and 1903. He also wrote a biography of C. G. J. Jacobi. [2] Königsberger's own research was primarily on elliptic functions and differential equations. He worked closely with Lazarus Fuchs, a childhood friend. [2]
The namesake of the association is the German physiologist and physicist Hermann von Helmholtz. [2] The annual budget of the Helmholtz Association amounts to €5.8 billion, of which about 70% is raised from public funds. The remaining 30% of the budget is acquired by the 19 individual Helmholtz Centres in the form of contract funding.
The concept of free energy was developed by Hermann von Helmholtz, a German physicist, and first presented in 1882 in a lecture called "On the thermodynamics of chemical processes". [1] From the German word Arbeit (work), the International Union of Pure and Applied Chemistry (IUPAC) recommends the symbol A and the name Helmholtz energy. [2]

In the history of thermodynamics, Thermodynamik chemischer Vorgänge (Chemical thermodynamic process) is a sequence of three papers (1882–1883) written by German physicist Hermann von Helmholtz. It is one of the founding papers in thermodynamics, along with Josiah Willard Gibbs's 1876 paper "On the Equilibrium of Heterogeneous Substances".
The naming of individual Cs using the Helmholtz system. Helmholtz pitch notation is a system for naming musical notes of the Western chromatic scale.Fully described and normalized by the German scientist Hermann von Helmholtz, it uses a combination of upper and lower case letters (A to G), [a] and the sub- and super-prime symbols ( ͵ ′ or ⸜ ⸝) to denote each individual note of the scale.
The Helmholtz decomposition in three dimensions was first described in 1849 [9] by George Gabriel Stokes for a theory of diffraction. Hermann von Helmholtz published his paper on some hydrodynamic basic equations in 1858, [10] [11] which was part of his research on the Helmholtz's theorems describing the motion of fluid in the vicinity of vortex lines.
