Portrait of Marcello Malpighi (1628-94),Italian biologist and inventor of the microscope. Following the theories of Galileo,Malpighi was the first to build a microscope,slightly ahead of Leeuwenhoek. He was a physician by training,graduating at Bologna in 1653. Malpighi's observations through his microscope were to revolutionise anatomy. He showed a mechanism for the transfer of air into the blood in the lungs,and observed capillary vessels for the first time. This completed the theory of blood circulation advanced by Harvey. After a life of research and lecturing,he spent his last three years as private physician to Pope Innocent XII | |
