Loeb, Jacques (1859–1924)
Jacques Loeb was a German-born American biologist who studied the chemical processes of living
organisms. He stressed the importance of physical and chemical laws in understanding
life phenomena in both animals and plants. He is best known for his work
on parthenogenesis, especially his
induction of artificial parthenogenesis in the eggs of sea
urchins and frogs, thereby highlighting the biochemical nature of fertilization.
