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.
