Over the years, real theodolites have been used by famous scientists, engineers, and explorers. Lewis and Clark carried a theodolite on their expedition to explore the American west. George Washington, Thomas Jefferson, and Abraham Lincoln used theodolites for land surveying. You can see Jefferson's theodolite on display at Monticello.
In modern times, theodolites are valuable tools in science and engineering, and are used in the surveying and construction industries. The theodolite is a "go-to" instrument for all types of land, sea, air, and space measurements.
