My first attempts to transmit typhus to laboratory animals, including the smaller species of monkeys, had failed, as had those of my predecessors, for reasons which I can easily supply today.

I was less successful in my attempts to effect preventive vaccination against typhus by using the virus and in trying to produce large quantities of serum using large animals.

I finally demonstrated that typhus infection is not hereditary in the louse.

They say politics is a contact sport, and I have to agree with that.

Contagion has become very much a phenomenon, and it's a phenomenon of globalization.

I grow daily to honour facts more and more, and theory less and less. A fact, it seems to me, is a great thing; a sentence printed, if not by God, then at least by the Devil.
