The Keys and the Mosquito.
About twenty-five years ago, I wrote a piece about the elusive threat of nighttime, the mosquito that announces its arrival with its unbearable noise. I remembered Paul Müller, inventor of DDT, who received the Nobel Prize in 1948 and contributed to unleashing the passion for fumigation that dominated the second half of the 20th century. A peculiar idea of health led housewives to spray poison in every corner without taking a cigarette out of their mouths.
