Beyond great-man narratives: case studies and sources in history of science

[Aria.S]

I'm developing a new university seminar on the history of science, and I want to move beyond the standard "great men and their discoveries" narrative to explore how scientific ideas are shaped by their cultural, economic, and political contexts. I'm particularly interested in case studies where failed theories or roadblocks reveal as much about the process as the breakthroughs do, like the long path to accepting germ theory or the social factors influencing the development of early genetics. For scholars and educators in this field, what are some of the most compelling but often overlooked episodes or figures you include to challenge simplistic progress narratives? How do you effectively integrate primary sources and historiography into the curriculum to help students critically analyze how scientific knowledge is constructed and contested, rather than just passively receiving a timeline of facts?

Great topic for a seminar that moves beyond the heroic narrative. Here are a few compelling, teachable episodes and angles you can build around:

1) Spontaneous generation to germ theory. Contrast Redi’s controlled experiments with Spallanzani and Pasteur’s swan-neck designs. Make students map how experimental design, replication, and prevailing beliefs shaped acceptance of germ theory, not just “facts.”
2) Semmelweis and the battle over hand hygiene. Focus on data, medical culture, and how a simple intervention faced institutional inertia; it’s a perfect case for discussing how small failures at scale can derail a big idea.
3) Mendel’s work and its social afterlife. Start with Mendel’s pea experiments, then trace the delayed recognition and how early genetics intersected with social currents (eugenics, public health, and the politics of heredity).
4) Lysenkoism and the politics of biology in the USSR. Show how political priority and dogma can suppress robust experiments, and how resilience of a wrong theory can delay progress for a generation—great for discussing science as a social project.
5) Rosalind Franklin, DNA structure, and the sociology of scientific credit. Use this to discuss gender, attribution, and the collaborative nature of big discoveries.
6) Race, genetics, and the misuse of science in the late 19th/early 20th centuries. A cautionary thread that helps students see how cultural values shape research questions and interpretations.

For each episode, pair a primary source with a concise secondary narrative and end with a reflection prompt about what the episode reveals about how science actually progresses, not just what happened.

If you want, I can sketch a 6‑week syllabus around these case studies with suggested primary sources and a grading rubric.
