On November 19, 1955 Italy issued this 25 lire stamp (Sc #701) to commemorate the 30th anniversary of the death of physician and zoologist Giovanni Battista Grassi (1854-1925). Dr. Grassi is best known for his pioneering work in parasitology.

From wikipedia, "His works in malaria remain a lasting controversy in the history of the Nobel Prizes, because a British army surgeon, Ronald Ross, who discovered the transmission of the malarial parasite in birds was given the 1902 Nobel Prize in Physiology and Medicine. But Grassi, who demonstrated the complete route of transmission of human Plasmodium, and correctly identified the types of malarial parasite as well as the mosquito vector, Anopheles claviger, was denied."

The title of the thread (Optical Instruments: Microscopes, Binoculars, Sextans, Theodolits, Hand Scopes) isn't limitative to optical instruments that are welcome in this topic. Optical instruments that helps our society to activities that are turned to our own planet - to research, to spy, to observe, to prevent and protect. But 'optical' (must have lenses). Only the human eyes and evaluation for what he/she is seeing.
