It took Friedrich Georg Wilhelm von Struve 39 years to measure the Earth. He started in 1816 at the Dorpat Observatory in Estonia. From there, under his leadership, a team of scientists triangulated a line up to Hammerfest in Norway, and down to the Black Sea.
When he finished in 1855, Struve had the first accurate measurement of a meridian and was able to calculate the exact size and shape of the Earth. It was a huge leap forward for science and helped cartographers to make more precisely scaled maps.
