Three centuries. Sixteen scientists. One invisible world brought into focus.
Follow how a curiosity about “wee beasties” became the science that gave us
sterile technique, germ theory and antibiotics.
Each era answered a question the previous one could not.

The timeline stops in 1953, the same year the structure of DNA was published. What began with a draper grinding lenses in Delft had, within three centuries, become a science capable of reading and rewriting the instructions inside a cell. Sequencing, recombinant DNA, the microbiome and CRISPR are all continuations of the same line of questioning: what is out there, what does it do, and how do we work with it?
Every technique in your practical class was somebody's discovery once.
