The birth of the financial press in the UK in the early nineteenth century corresponded with a series of financial crises, from the crash of 1825, through the railway manias of the 1830s and 1840s, to the collapse of Overend and Gurney in 1866. Both boom and bust stimulated the demand for information, and a new breed of specialist journalist emerged to provide it. This chapter considers these pioneers of financial journalism, exploring how they viewed their responsibilities to readers, and assessing their role in an unstable and rapidly expanding market economy.
