In autumn 1820, Arthur Mowbray (1757-1840) established the Hetton Coal Company, by dint, as his former employer and rival later described it, of prowling round the Royal Exchange to raise funds.
Charles Lord Stewart (Marquess of Londonderry from 1822) had sacked Mowbray as manager of the Vane-Tempest collieries in 1819 and appointed John Buddle as his successor. Mowbray’s response was to use the expertise gained from many years in the coal trade, land agency and banking to set up a rival enterprise buying up coal leases round Hetton le Hole.
