Andrew Lamb (c1803-1881), Chief Engineer of the Peninsular and Oriental Steam Navigation Co
1848 The Canton, built for P&O by Tod, McGregor and Co, was fitted with a boiler blow-off system to prevent build up of salts - this had been introduced by Mr Lamb, superintendent engineer of P&O; the ship was also equipped with Lamb's patent life boats.
1852 Andrew Lamb described the Lamb and Summers type of boiler at the I.Mech.E; this was a boiler with narrow vertical flat-sided flues instead of tubes, as this arrangement was easier to keep clear of soot and fine ashes. It was used in P&O vessels in the 1850s

1859 Patent. '2815. And Andrew Lamb and William Alltoft Summers, both of Southampton, in the county of Hants, Engineers, have given the like notice in respect of the invention of "improved arrangements of apparatus for superheating steam."'
