Henri Cassini

Henri Cassini, born on May ninth, seventeen eighty-one, was a distinguished French botanist and naturalist renowned for his expertise in the sunflower family, Asteraceae, previously known as Compositae. As the youngest of five children of Jean-Dominique, Comte de Cassini, he hailed from a family steeped in scientific achievement, with his father being the director of the Paris Observatory and a notable cartographer who completed the map of France.

Henri's lineage traced back to the illustrious Giovanni Domenico Cassini, an Italian-French astronomer celebrated for his discoveries, including Jupiter's Great Red Spot and the Cassini division in Saturn's rings. This rich heritage undoubtedly influenced Henri's passion for the natural sciences, leading him to make significant contributions to botany.

Throughout his career, Cassini named numerous flowering plants and new genera within the Asteraceae family, many of which originated from North America. His scholarly output was impressive, with sixty-five papers and eleven reviews published in the Nouveau Bulletin des Sciences of the Société Philomatique de Paris between eighteen twelve and eighteen twenty-one. Notably, in eighteen twenty-five, he established a new genus, Nabalus, for the North American taxa of Prenanthes.

In eighteen twenty-eight, he honored the Scottish naturalist Dugald Stewart by naming Dugaldia hoopesii after him. The botanical community recognizes Henri Cassini through the standard author abbreviation Cass., which is used to cite his contributions to botanical nomenclature.
