Heinrich Wilhelm Brandes (German: [ˈbʀandəs]; 27 July 1777 – 17 May 1834) was a German physicist, meteorologist, and astronomer.

Brandes was born in 1777 in Groden near Ritzebüttel (a former exclave of the Free Imperial City of Hamburg, today in Cuxhaven), the third son of Albert Georg Brandes, a preacher. He studied at the University of Göttingen from 1796 to 1798 under Abraham Gotthelf Kästner and Georg Christoph Lichtenberg. Carl Friedrich Gauss was a fellow student. He attained his doctorate in 1800, and spent a short time teaching privately. As an astronomer, he was noted for demonstrating that meteors occur in the upper atmosphere and thus not really a meteorological phenomenon.[1]

From 1801 to 1811 he was at first a technical designer of dykes on the Weser river at Eckwarden, Butjadingen, in the Duchy of Oldenburg, and later a dyke inspector for the lower right bank of the Weser.

In 1811 he became a professor of mathematics at the newly created University of Breslau, a merger of two Wrocław colleges. In 1826 he gained the chair of physics at the University of Leipzig.

He had a very wide range of activities. He wrote a considerable number of mathematics textbooks. In 1820 he published the first weather charts in Beiträgen zur Witterungskunde ("Contributions to Meteorology"). Thus he is considered to be a founder of synoptic meteorology. In 1824 he developed a new method to compute the Euler constant numerically. He died on 17 May 1834 in Leipzig and was buried in the Alter Johannisfriedhof.
