Schwabe’s father was a physician, and the family apothecary business was derived from his mother’s family. After working from 1806 to 1809 as an assistant in the business, Schwabe continued his pharmaceutical studies at the University of Berlin in 1810–1812, under Klaproth and Hermbstädt While at Berlin he became interested in astronomy and botany. Schwabe worked as an apothecary from 1812 until 1829, when he sold the business in order to give his time fully to his scientific interests.
On 17 December 1827 Schwabe rediscovered the eccentricity of Saturn’s rings. In 1843 he made his first definite statement regarding the periodicity of sunspots, giving statistics for 1826–1843. He tabulated his results under four headings: the year, the number of groups of sunspots in the year, the number of days free from sunspots, and the number of days when observations were made. Schwabe realized that with the modest apparatus in his private observatory, numerical determination was difficult: for instance, on days when there was a large number of spots, he had probably underestimated them. His carefully compiled results demonstrated the existence of periodicity, although he wrongly

Heinrich Schwabe
German astronomer (1789–1875)
Samuel Heinrich Schwabe (25 October 1789 – 11 April 1875) was a German amateur astronomer remembered for his work on sunspots. He observed sunspots and made drawings of them from 1825 to 1867 and suggested in 1838 that there may be a ten-year cycle of sunspot activity. He also took an interest in botany and was a founding member of a natural history society in Dessau.
Life and work
[edit]Schwabe was born in Dessau, Germany, where his father was a physician to the duke. His mother was the daughter of apothecary Johann H. G. Häseler (1740-1812) and he too trained to be one in 1806 by joining the Dessau Mohrenapotheke owned by Häseler. After about three years he began to study at the University of Berlin training in pharmacy under Martin Heinrich Klaproth and Sigismund Friedrich Hermbstädt. He also took an interest in astronomy and botany and was forced to stop studies when his grandfather Häseler fell ill. After the death of Häseler in 1812, Schwabe was forced to take over the family pharmacy business and the family became prosperous. He spent his spare time in scientific pursuits but it was only after selling off the business that he began to attend to scientific activities fulltime.[1]
Schwabe obtained his
