John Arthur Roebuck (28 December 1802 – 30 November 1879), British politician, was born at Madras, in India. He was raised in Canada, and moved to England in 1824, and became intimate with the leading radical and utilitarian reformers. He was Member of Parliament (M.P.) for Bath from 1832 to 1847, and M.P. for Sheffield constituency from 1849. He took up that general attitude of hostility to the government of the day, be it what it might, which he retained throughout his life. He twice came with especial prominence before the public—in 1838, when, although at the time without a seat in parliament, he appeared at the bar of the Commons to protest, in the name of the Canadian Assembly, against the suspension of the Canadian constitution; and in 1855, when, having overthrown Lord Aberdeen's ministry by carrying a resolution for the appointment of a committee of inquiry into the mismanagement in the Crimean War, he presided over its proceedings.
John Arthur Roebuck was born at Madras in 1801, was fifth son of Ebenezer Roebuck, a civil servant in India, and was a grandson of the inventor John Roebuck. He was taken to England in 1807 following the death of his father. His mother remarried and he was taken to Canada, where he was educated. He returned to England in 1824, and was entered at the Inner Temple, and called to the bar in 1831. He married, in 1834, Henrietta, daughter of Thomas Falconer. In 1835 he became agent in England for the Legislative Assembly of Lower Canada during the dispute between the executive government and the House of Assembly. In 1838, when, although at the time without a seat in parliament, he appeared at the bar of the Commons to protest, in the name of the Canadian Assembly, against the suspension of the Canadian constitution. In 1843 he was appointed Queen's Counsel, and was elected a bencher of his inn.
