Lorenz, Ludvig

The fact that the thermal conductivity in a pure metal is dominated by the free electron contribution was Ulustrated in 1853 by Gustav Wiedemann (1826-1899) and Rudolf Franz (1827-1902), who showed that Xei and the electrical conductivity, (Tei, are proportionally related (Wiedemann and Franz, 1853). A few years later Danish physicist Ludvig Lorenz (1829-1891) realized that this ratio scaled hnearly with the... 

The name of this gauge refers to the Dutch physicist Hendrik Antoon Lorentz (1853-1928), whereas the gauge was really introduced by the Danish physicist Ludvig Valentin Lorenz who not only introduced this gauge as well as their retarded solutions (91), but also independently developed Maxwell s equations [39]. 

Rudolph Franz, born Dec. 16,1826, in Berlin, Germany, died Dec. 31, 1902, in Berlin, Germany. Ludvig Lorenz, born Jan. 18, 1829, in Helsingpr, Dutch, died Jun. 9, 1891. 

Incidentally, the Lorenz gauge was proposed by the Danish physicist Ludvig Lorenz, It is often erroneously designated Lorentz gauge, after the more famous Dutch physicist Hendrik Lorentz. In fact, the condition does fulfill the property known as Lorentz invariance.)... 

The Lorentz—Lorenz equation is named after the Danish mathematician and scientist Ludvig Lorenz, who published it in 1869, and the Dutch physicist Hendrik Lorentz, who discovered it independently in 1878.
