Franz Ernst Neumann
Franz Ernst Neumann (11 September 1798 – 23 May 1895) was a German mineralogist, physicist and mathematician. Biography Neumann was born in Joachimsthal, Margraviate of Brandenburg, near Berlin. In 1815 he interrupted his studies at Berlin to serve as a volunteer in the Hundred Days against Napoleon, and was wounded in the Battle of Ligny. Subsequently, he entered Berlin University as a student of theology, but soon turned to scientific subjects. His earlier papers were mostly concerned with crystallography, and the reputation they gained him led to his appointment as Privatdozent at the University of Königsberg, where in 1828 he became extraordinary, and in 1829 ordinary, professor of mineralogy and physics. His 1831 study on the specific heats of compounds included what is now known as Neumann's Law: the molecular heat of a compound is equal to the sum of the atomic heats of its constituents. Devoting himself next to optics, he produced memoirs which earned him a high place ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Steffeck
Carl Constantin Heinrich Steffeck (4 April 1818, Berlin – 11 July 1890, Königsberg) was a German painter and graphic artist. He was especially well known for his paintings of horses and dogs. Life He was the son of a "gentleman of independent means" who was interested in art. While he was still in the Gymnasium he sat in on classes at the Prussian Academy of Arts. In 1837, he entered the master class of horse painter Franz Krüger and later worked in the studios of Carl Joseph Begas. He went to Paris in 1839, where he spent two months studying with Paul Delaroche and was influenced by the work of Horace Vernet. From 1840 to 1842, he lived in Italy. When he returned, he devoted himself primarily to paintings of hunters and animals. Over time, he concentrated more on horses; at rest, exercising, engaging in sports etc., but he continued to paint portraits of all sizes as well as historical paintings, lithographs, etchings, and even some small bronze animal sculptures.

Neumann's Law
Neumann's law states that the molecular heat in compounds of analogous constitution is always the same.
