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’.
