Patrick Manson graduated as a doctor from Aberdeen University in 1865 and became a medical officer in China. He became interested in elephantiasis, a common disease there, and showed that the life cycle of the causative organism included both man and mosquito and by controlling mosquitoes the disease could be controlled. He became convinced that the same was true of malaria and this theory was proved correct by Sir Ronald Ross in 1898. Manson also discovered several other parasitic organisms.
