Jacob Grimm (1785-1863) and Wilhelm Grimm (1786-1859) were born in Hanau, Germany. The brothers were inseparable despite their differing temperaments: Jacob was introverted, serious and robust; Wilhelm was gregarious and asthmatic. They published the first of their many collections of fairy tales in 1812. The story that they wandered about Germany collecting their tales from the lips of peasants is a fairy tale itself. In fact, they invited educated middle class women into their home to tell them the stories they had heard from their governesses and servants. The point of their collection of folklore was to study the German language and they also did important work on the German dictionary. The stories were revised to be more appropriate for children in 1819 and were published under the title Children's and Household Tales. By the beginning of the twentieth century Children's and Household Tales was second only to the Bible in the German bestseller lists.
