Immunity in infective diseases

In this landmark 1905 volume, a pioneering scientist revisits twenty‑five years of research into how the body defends itself against infectious diseases. Drawing on countless experiments and a lively exchange with contemporary critics, he builds a clear narrative that links the ancient observation of inflammation with the emerging concept of cellular immunity. The work is framed as a response to heated debates at an international congress, making the history of scientific argument come alive.

Listeners will be guided through the core of the phagocytic theory, learning how microscopic cells engulf pathogens and how this process underpins the body’s natural resistance. Detailed illustrations accompany the text, helping to visualize the mechanisms that were once controversial but are now foundational to modern immunology. The author’s candid reflections on opposition and collaboration give a human dimension to the science, offering both a thorough overview and a glimpse into the mindset of early 20th‑century research.
