In 1849 he became chairman of the York, Newcastle and Berwick Railway, succeeding his rival the 'Railway King' George Hudson after Leeman's investigations helped uncover Hudson's illegal share dealing. Leeman was deputy chairman of the successor company, the North Eastern Railway, from 1855 to 1874 and chairman from 1874 to 1880, having encouraged its formation through mergers in 1854, and he was a chairman of the Railway Association of Great Britain. Leeman resigned as chairman of the NER in 1880 after the failure of his mining company reduced his wealth and harmed his health. He remained a member of the board until his death two years later.
Other business
He was involved the 1860s in developing iron ore mining at Rosedale for Teesside steel works, co-owning the Rosedale and Ferryhill Iron Company from 1860 to 1877. He was a director of the York Herald and chairman of the Yorkshire Banking Company from 1867 to 1880.
Political career
He became a Liberal councillor for Castlegate Ward in 1836 and for Guildhall Ward in 1839, and was an Alderman for 28 years from 1850. He was elected Lord Mayor of York three times in 1853, 1860, 1870, and was the Member of Parliament for York 1865–8 and 1871–80, having first stood for Parliament in 1852. When Anthony Trollope campaigned in Beverley as a Liberal candidate, Leeman warned him against it; Trollope came last due to corruption and vote-buying.
Personal life
Leeman was born in York, the son of George Leeman, a greengrocer. He lived at The Mount, York, and married twice, first to Jane Johnson in 1835, and second to Eliza, the widow of Rev. Charles Payton, in 1863. One son, William Luther Leeman, attended St. Edmund Hall, Cambridge, and University College, Durham, and was Rector of Middleton St. George, 1874–6, Vicar of Rosedale, Yorkshire, 1877–9, and of Seaforth, Lancashire, 1879–82. His second son, Joseph Johnson Leeman, became a partner in Leeman and Wilkinson and succeeded George as MP for York. Another son, Francis Lawley Leeman, attended Westminster School and Trinity College, Cambridge. George also had at least three daughters, including Priscilla. He was a member of the Reform Club and the Yorkshire Philosophical Society from 1844. He died in Scarborough in 1882. A statue of Leeman by local sculptor George Walker Milburn, paid for by public subscription, was unveiled in 1885 and stands outside York railway station; Station Road was renamed Leeman Road at the same time.
