Jussieu, Antoine-Laurent de (1748–1836), a French botanist. One of a family of five distinguished botanists, Jussieu studied under his uncle, Bernard de Jussieu (1699–1777), whose work he incorporated into Genera Plantarum (1788–89), a treatise on plant classification. It divided plants into three primary divisions—the acotyledons (plants lacking seed leaves), the monocotyledons (plants with one seed leaf), and the dicotyledons (plants with two seed leaves). Plants were further grouped into 100 families, many of which are still recognized today. Jussieu was professor at the Museum of Natural History, Paris, 1793–1826, and organized its botanical collections.
Albert Einstein was a pretty smart guy. When you look up the word "genius" in the dictionary, so the saying goes, it's a pretty safe bet you'll see Einstein's mug. Think you’re smart enough to take on a quiz about the famed thinker?
