Paul Ehrlich was a young scientists when he joined the research team of Robert Koch. He, along with anothe Scientist, Emi Behring, developed an interest in the antibodies produced by the human body.His studies of these led him to believe that a chemical substance could be produced to work alongside these antibodies, killing specific bacteria without harming the rest of the body.

This line of research led to Ehrlich opening his own research institute, to search for 'The Magic Bullet'. The 'Magic Bullet' was the name given to the much sought after dye or drug that would counter act the spread of infection.

His results were a limited success: he found dyes that attacked malaria and some sleeping sickness bugs. In 1906 the detection by Hoffman of the microbes that caused syphilis opened up a new line of research. Ehrlich's team tested over 600 chemical compounds, searching for one that would target and destroy the syphilis germ. In 1909, a new scientist joined his team. He was asked to retest all of the discarded chemicals that had previously been shown to fail. The 606th compound selected and destroyed the germ. Ehrlich rigorously tested the vaccine and in 1911 Savarsan 606 was used for the first time on Humans.

Ehrlich's work with Behring led to a cure for Diptheria, he also researched extensively into the field of chemotherapy, for which he was awarded the Nobel Prize for Medicine in 1908.
