Edward Baines, of St Ann's Hill, Leeds, was the second son of Edward Baines, proprietor of the Leeds Mercury and MP for Leeds in the 1830s, and his wife Charlotte Talbot. His elder brother, Matthew Talbot Baines, was also a politician. Edward Baines junior was educated at a Leeds private school and then at a dissenting academy – the Leaf Square grammar school at Pendleton, near Manchester. From 1815 he worked as a journalist on the Leeds Mercury, becoming a junior editor c 1820 and a partner in the business in 1827. He became sole editor when his father was elected to Parliament in 1834, and, after his father's death in 1848, proprietor of the Leeds Mercury. He served as Liberal MP for Leeds from 1859 to 1874. He was knighted in 1880. A political Liberal, he supported the 1832 Reform Act and the 1834 new poor laws; he was an advocate of repeal of the corn laws and of the separation of church and state. He was an opponent of the factory reform movement and responsible for the Mercurys rejection of Richard Oastler's letters to it on the subject. A staunch Dissenter, he opposed state-sponsored education. In 1843 he wrote in the Mercury that education was something individuals could do for themselves "under the guidance of natural instinct and self-interest, infinitely better than Government could do for them". Hence "All Government interference to COMPEL Education is wrong" and had unacceptable implications: "If Government has a right to compel Education, it has right to compel RELIGION !" He withdrew his opposition in the 1860s, when he reluctantly conceded the inadequacy of efforts for the voluntary provision of education. In the 1860s he repeatedly introduced bills to widen the franchise; all were defeated. Baines helped to found the Leeds Literary and Philosophical Society. He was also a prominent advocate of working-class adult education, founding Yorkshire Mechanics' Institutes in imitation of George Birkbeck's London mechanics' institute. Contributions of his on the cotton industry to his father's History of Lancashire were praised by reviewers; at their suggestion his History of the Cotton Manufacture was published separately with much additional material. He also wrote a number of more polemical works; e.g. criticisms of Owenism. In 1840 he attended the World's Anti-Slavery Convention where he was captured in a group painting. He married Martha Blackburn in 1829. Baines died on 2 March 1890 in Leeds, and was interred in the family vault at Woodhouse Cemetery.
