Some context, in case you spent the better part of last night googling eclampsia

For no particular reason, here is a graph of maternal mortality rates in England and Wales between 1850 and 1970. The Daily Beast also has an informative article on eclampsia, specifically, though you should be aware that it contains many television spoilers. Particularly interesting to me: We still don't actually know what causes eclampsia — and the treatments still revolve around preventing the seizures. (Thanks to Ms. Rosenberg for the graph!)
