The early Victorian era before the reforms of the 1840s became notorious for the employment of young children in factories and mines and as chimney sweeps. Child labour played an important role in the Industrial Revolution from its outset: novelist Charles Dickens, for example, worked at the age of 12 in a blacking factory, with his family in a debtors' prison. Reformers wanted the children in school: in 1840 only about 20 percent of the children in London had any schooling. By 1860 about half of the children between 5 and 15 were in school (including Sunday school).
