"Paul Epstein" was a Germany/German mathematician. He was known for his contributions to number theory, in particular the Epstein zeta function.

Epstein was born and brought up in Frankfurt, where his father was a professor. He received his PhD in 1895 from the University of Strasbourg. From 1895 to 1918 he was a Privatdozent at the University in Strasbourg, which at that time was part of the German Empire. At the end of World War I the city of Strasbourg reverted to France, and Epstein, being German, had to return to Frankfurt.

Epstein was appointed to a non-tenured post at the university and he lectured in Frankfurt from 1919. Later he was appointed professor at Frankfurt. However, after the Nazis came to power in Germany he lost his university position. Because of his age he was unable to find a new position abroad, and finally committed suicide by barbital overdose at Dornbusch (Frankfurt am Main)/Dornbusch, fearing Gestapo torture because he was a Jew.

That prospect is deeply troubling, because infectious illness is a genie that can be very hard to put back into its bottle. It may kill fewer people in one fell swoop than a raging flood or an extended drought, but once it takes root in a community, it often defies eradication and can invade other areas.

We are looking at an emergence of new diseases and a resurgence of old diseases, and redistribution of old diseases on a global scale.

Further, the lack of clean water during a drought interferes with good hygiene and safe rehydration of those who have lost large amounts of water because of diarrhea or fever.

We found that impacts of climate change are likely to lead to ramifications that overlap in several areas including our health, our economy and the natural systems on which we depend.

Colonizers escaped (to mountainous areas) to avoid the swamps that bred malaria. Those areas are no longer safe.

In these days of international commerce and travel, an infectious disorder that appears in one part of the world can quickly become a problem continents away if the disease-causing agent, or pathogen, finds itself in a hospitable environment.

Clearly, the extreme events that we're now experiencing in California and Florida, and in Georgia and Alabama, and the ice storms in Maine and New Hampshire, are going to have an impact on our understanding that our climate system is becoming unstable.

Warmer winters and nights are altering the distribution of mosquito-borne diseases, while extreme weather events such as floods and droughts are spawning large.
