Coffee became popular with scholars as it sharpened the mind rather than dulled it like alcohol. Coffee houses became meeting places, debating chambers and even laboratories. Isaac Newton and Edmond Halley once dissected a dolphin on the table of a coffee house in London. Lloyd's of London and the Stock Exchange started life as coffee houses. But the craze had its detractors. The brewing of ale had long been the preserve of women, known as "brewsters" or "alewives". In 1674, a group of them – alarmed at falling trade in taverns – drew up the Women's Petition Against Coffee, claiming: "Coffee makes a man barren as the desert out of which this unlucky berry has been imported."
