In this book, a breakdown of the life and work of some of history's pioneers in the study of immunologists and virologists are thoroughly explored. As the world becomes more connected and bacteria become more antibiotic resistant, the importance of research within these two fields is becoming dyer. MRSA, Zika, SARS, and Ebola are just some of the recent outbreaks that have affected our communities. This opportune volume provides excellent biographical sketches for trailblazers in this area of science and will inspire readers to explore the top scientific contributors of the 21st century.
