17 jun 1767 año - Invention of caterpillar tracks

Descripción:

Inuan inventor and engineer Erik Ägeson created the first caterpillar tracks, what he called 'Allrganganí vagíar' (everlasting roads). It took him 26 years to improve the design and get enough funding to get a patent, although it went into production in 1788.
