Robert Thompson and Sons, ship builder of Sunderland
1854 Robert Thompson Junior left the Thompson family yard (see Joseph Thompson and Sons) in 1854 to move to Southwick in order to start trading under his own name. He purchased the patent slipway and shipbuilding yard of John Candish at Southwick, and soon after began building ships.
1864 The first ship was a wooden barque was Graces; 21 ships followed this until the first composite ship was built in 1864.
1868 Thompson was one of the pioneers of iron construction, the first of which was the full-rigged Ireshope.
1870 The first iron steamer produced by the yard was Canadian.
1871 The yard focused on only building in iron from this year onwards.
1881 The yard became Robert Thompson and Sons Ltd when Robert went into partnership with two of his sons. 12 ships were launched in this year, giving the yard the third highest output on the river.
1888 Steel replaced iron in both Thompson yards, and a number of steel tramps were built at the yard. Also during this year, the yard purchased the Bridge Dockyard, mainly for repair work. Later, ships were launched broadside from this yard, because of the narrowness of the site.
