John Lewis Ricardo

John Lewis Ricardo (1812 – 2 August 1862) was a British businessman and politician.

Early life Ricardo was born in London in 1812. He was the eldest son of financier Jacob Ricardo and nephew of the economist David Ricardo.

Career Following the death of his father in 1834, Ricardo abandoned his plans for a career in the British Army and, instead, took over his father's financial firm, in partnership with his uncle, Samson Ricardo. He is of Sephardic-Jewish descent.

Ricardo was a leader of a group of businessmen who, in 1845, purchased the patents for the electric telegraph designed by Cooke and Wheatstone. Ricardo was Electric Telegraph's largest shareholder, and its executive chairman, for its first 12 years. His goal was to build a network that would distribute breaking financial news to his own newsrooms adjacent to all British stock exchanges—an information monopoly that would be valuable to speculators and investors. However, when the established telegraph companies formed monopolistic cartels and raised prices to newspapers, Ricardo secretly switched sides and campaigned for their nationalization.

Political career In 1841 he was elected Member of Parliament for Stoke-on-Trent as a Liberal, serving until his death.

Personal life In 1841, he married Catherine Duff (–1869), the daughter of General Sir Alexander Duff and sister of James Duff, 5th Earl Fife. Together, they had one son:

Ricardo died in West Brompton on 2 August 1862.
