(March 14, 1854 – August 20, 1915)

Born on March 14, 1854, Paul Ehrlich is exactly one-quarter of a century older than Albert Einstein. And regardless of who you are, your life depends on his contributions to science more than it does to anything Einstein contributed. Influenced by Robert Koch, Paul Ehrlich is famous for his groundbreaking works on bacteriology, immunology and chemotherapy. He was the first person to accurately describe the mechanism of antibody formation. This enabled him to set the criteria which therapeutic sera must meet. He also pioneered potent chemotherapies, which he gave the “magic bullet” euphemism. His 19th century research-findings opened the door to unprecedented knowhow and discoveries, which improved both lifespan and quality of life in the 20th century. Dreaded diseases such as diphtheria and syphilis, whose mortality rates were astronomical in the previous centuries, were eventually curtailed. It was in his lab in 1907 that Albert Bertheim first produced arsphenamine (also known as Salvarsan). Two years afterwards, Sahachiro Hata successfully demonstrated its effectiveness against Treponema pallidum: the etiological agent of syphilis. Although Ehrlich made several other contributions to medicine, the most noted are in combating pathogens through immunology and chemotherapy. His contributions to prolonging your life cannot be overemphasized.
