The video below offers a fairly charming history of Cell Theory, basically the idea that living things are made up of cells and that cells come from pre-existing cells. I’m not sure why the video describes the course of discovery as “weird” and “wacky”, but what strikes me in particular is that the human foibles involved seem all too familiar. Hooke feuded with Newton, Schleiden feuded with Schwann. To this day we decry the involvement of personalities in science, which we want to be completely objective and somehow above being influenced by human nature, cliques and hurt feelings. Plus ça change, plus c’est la même chose.
