Malpighi, Marcello

Malpighi, Marcello, 1628-94, Italian anatomist. A pioneer in the use of the microscope, he made many valuable observations on the structure of plants and animals. He completed Harvey's theory of circulation by his observation of the movement of blood through capillaries and recorded this, as well as his work on the structure of the lung, in De pulmonibus (1661). He is noted also for his studies of the structure of glands and of the brain, spleen, liver, and kidneys; of the anatomy of the silkworm; of the embryology of the chick; and of plant tissues. Several anatomical parts bear his name, including a layer in the human skin and the excretory tubules in insects. He was professor at the Univ. of Bologna (1666-91).
