Prussian Army lieutenant Wilhelm Filchner led Germany's second expedition in the early 20th century. While the government stayed largely hands off the expedition committee put their oar in enough to see der Deutschland sail under a syphilitic commander whose antics placed everyone's lives in danger and gave us a really good example of the sort of problems split leadership can cause in a high latitudes project. Suspected suicide, suspected fake appendicitis and very definite mania and toastiness characterised Filchner's time in the south.
