Anton von Leeuwenhoek, the father of microscopy, discovered a sacred crystalline substance when he first observed his own semen with a microscope in 1674. In 1678, he reported this discovery to the Royal Society. Several scientists subsequently discovered this independent crystalline compound, called spermine, over the next 200 years, but it was not until 1920 that the chemical structure of spermine, as well as the chemistry of another related molecule, spermidine, was revealed structure.
