Jacques Loeb

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.
