Lesson Summary

In this GCSE lesson from the unit Medicine Through Time: Change and Continuity in Health and Disease, students analyse how Louis Pasteur proved that microbes cause decay and human disease through controlled experiments and microscopic observation. They evaluate Robert Koch’s methods in isolating specific bacteria responsible for killer diseases, exploring how his laboratory techniques transformed diagnosis and scientific investigation. Students assess how technology, rivalry and international competition accelerated public health reform and shaped modern medical policy.
