Fehon was born in London, a son of Sarah Fehon, née Greenhaus, and John Fehon, in business as a printer. He was educated at Brixton school, and started work as a clerk in 1851. He was next employed by
Eastern Counties Railway followed by two years with Canada's
Great Western Railway. Following an invitation by his brother, and in 1869
traffic manager. Fehon resigned in 1872 to join the freight business of William McCulloch & Co. In 1880 the company expanded its operations by association with Wright Heaton & Co., a New South Wales freight company. In 1888, at the invitation of Premier
Henry Parkes, he accepted a seven-year appointment as one of the Commissioners of Railways in New South Wales under
E. M. G. Eddy. In 1889 charges were levelled against Fehon, that McCulloch & Co., and Wright Heaton & Co. received preferential treatment from the Victorian railways in the carriage of
bales of wool, being charged the 250lb rate for some 400lb bales, but collecting the full price from consignees. Despite lack of evidence against Fehon,
Jack Want called a successful
censure motion on Premier Parkes, who subsequently resigned. In 1896 Fehon was offered a position by the Victorian government but declined. He was reappointed by
G. H. Reid for a further seven years. In 1902 he was reappointed by Sir
John See for a further seven years. In 1906 the Legislative council passed the Railway Commissioners Appointment Act, with the provision that it should not take effect until a new set of commissioners had been selected. So Fehon retired in April 1907 along with
David Kirkcaldie and Chief commissioner
C. N. J. Oliver was replaced by
Tom Richard Johnson. ==Family==
