Horatio William Bottomley (23 March 1860 – 26 May 1933) was an English financier, journalist, editor, newspaper proprietor, swindler, and Member of Parliament. He is best known for his editorship of the popular magazine John Bull, and for his patriotic oratory during the First World War. His career came to a sudden end when, in 1922, he was convicted of fraud and sentenced to seven years imprisonment.
Bottomley spent five years in an orphanage before beginning his career, aged 14, as an errand boy. Subsequent experience as a solicitor's clerk gave him a useful knowledge of English law, which he later put to effective use in a number of court appearances. After working as a shorthand writer and court reporter, at 24 he founded his own publishing company which launched numerous magazines and papers including, in 1886, the Financial Times. He over-reached himself with an ambitious public flotation of his company, which led to his first arraignment on fraud charges in 1893. Despite evidence of malpractice, Bottomley, who defended himself, was acquitted. He subsequently amassed a fortune as a promoter of shares in gold-mining companies.
