Hermann von Fehling

(b Hy?res, France, 10 Sept 1909). German architect. He studied architecture at the Baugewerkschule in Hamburg, although he first worked as a joiner's apprentice. He was in private practice in Berlin from 1945 until 1953, when he formed a partnership with Daniel Gogel (b 1927), also working with Peter Pfankuch (1925-77), a former assistant to Hans Scharoun until 1958. Fehling and Gogel made their name in Berlin with the pavilion for the Interbau exhibition (1956-7) at Hansaviertel, Berlin, and by winning second prize in the Berlin Philharmonie competition (1956). Thereafter came a series of distinctive buildings, including seven private houses, two churches, two parish centres and a student village, as well as housing, shops, offices and exhibitions. A worklist of 1980 contains 18 competition entries, of which 12 gained prizes, eight being firsts.

Hermann von Fehling

Hermann von Fehling (9 June 18121 July 1885) was a German chemist, famous as the developer of Fehling's solution used for estimation of sugar.

He was born in Lübeck. With the intention of taking up pharmacy he entered Heidelberg University about 1835. After graduating he went to Gießen as preparateur to Justus von Liebig, with whom he elucidated the composition of paraldehyde and metaldehyde. In 1839, on Liebig's recommendation, he was appointed to the chair of chemistry in the polytechnic in Stuttgart, a position he held for over 45 years. He died in Stuttgart in 1885.

His earlier work included an investigation of succinic acid, and the preparation of phenyl cyanide (better known as benzonitrile), the simplest nitrile of the aromatic series. Later his time was mainly occupied with questions of technology and public health rather than with pure chemistry.

Among the analytical methods he worked up the best known is that for the estimation of sugars. Known as Fehling's solution it is a solution of copper sulfate mixed with alkali and potassium sodium tartrate (Rochelle salt). He was a contributor to the Handworterbuch of Liebig, Friedrich Wöhler and Johann Christian Poggendorff, and to the Graham-Otto Textbook of Chemistry. For many years was a member of the committee of revision of the Pharmacopoeia Germanica.
