Scientific instruments made in York played a major role in the building of the Forth Bridge. Now that the bridge has been declared a World Heritage Site, it is worth remembering that the surveyors who worked out exactly where the bridge was to be built were using theodolites made in York by Thomas Cooke and Sons.

The contractors who were building the bridge wanted only the best, and Cooke theodolites were the finest in the world at that time. Mr Reginald Middleton, the engineer who determined the exact location of the bridge, described the theodolites as being ‘excellent’ and ‘practically indestructible’.
