Although most famous as a pioneer of aviation Sir George Cayley was also responsible for numerous other inventions and ideas. He patented a form of Caterpillar track, which he referred to as a ‘Universal Railway’ in 1826 and it seems to have worked on the same principle as the tracks were are familiar with today.
However despite the fact that his invention coincided with the age of steam there is no indication that Cayley had any idea of creating a self-moving machine along the lines of an agricultural tractor or indeed a tank.
Cayley, like many eminent men of his time, showed little or no interest in warlike applications of his inventions. He only wanted to solve the problem and improve things in a peaceful world.
