Anne Casimir Pyramus (orPyrame)de Candolle (20 February 1836,Geneva – 3 October 1918,Chêne-Bougeries) was aSwissbotanist, the son ofAlphonse Pyramus de Candolle.
He studiedchemistry,physics andmathematics inParis (1853–57), later spending time inEngland, where he met withMiles Berkeley. In 1859 he visitedAlgeria, and during the following year, continued his education inBerlin.[1] Afterwards, he returned to Geneva as an assistant and colleague to his father. He married Anna-Mathilde Marcet[when?] and they had four children: Raymond Charles de Candolle (1864–1935), Florence Pauline Lucienne de Candolle (1865–1943),Richard Émile Augustin de Candolle (1868–1920) and Reyne Marguerite de Candolle (1876–1958).[2]
In the field ofplant systematics, he used criteria such as stem structure and/orleaf arrangement as a basis of anatomical criteria. As aplant physiologist, he conducted investigations on the movement of leaves, the curling oftendrils, the effect of low temperatures onseed germination and the influence ofultraviolet radiation on flower formation. He was particularly interested in the botanical familyPiperaceae.[3]
He continued work onMonographiae phanerogamarum, a project begun by his father,[4] and was co-editor of theArchives des sciences physiques et naturelles (Geneva). He held honorary degrees (doctor honoris causa) from the universities ofRostock,Geneva,Aberdeen andUppsala.[3]
