Analysis of information sources in references of the Wikipedia article "Great Smog of London" in English language version.
These [death toll] numbers were startling, but they still caused no panic... A city hardened by war still believed the fog was simply a prolonged peasouper, just another byproduct of living in London.
For nearly a week London had been shrouded in fog. Today it had lifted a little (just enough for the half-choked inhabitants to see that there was a sun, still shining in the sky) but now it was settling down thicker than ever; it was for all the world like a dirty grey blanket.
As many as 100,000 people in London were made ill by the pollution at the time, particularly people with asthma and cardiovascular problems. The very young and the elderly also suffered.
