Part 5 · Context & review
History & people
A disease first sketched in 1908, named in 1958, made treatable in 1972 and explained at the molecular level only after 2014. Press play to run the playhead from 1900 to today, or jump between eras. The scene above the timeline redraws itself as each era arrives.
The scene is a drawing of what changed in each era; every caption in it repeats a milestone below, with that milestone's sources in the note panel. The axis is stretched after 1940 and again after 1990 so crowded recent decades stay readable. The outlook band is qualitative.
