Frank Bottrill

Life & Legacy

Frank Bottrill (1 April 1871 – 7 January 1953) was an Australian blacksmith and inventor, known for his giant "Big Lizzie" traction engine, thought to be at one time the largest in the world. It had a unique variant of the Dreadnaught Wheel design. Alternating bearing plates gave support to each wheel, allowing it to travel over soft ground without bogging down.
This was an early attempt to solve the problem that was later addressed more effectively by the caterpillar track. After running into financial difficulty, Bottrill spent the later part of his working life clearing bush and hauling loads in the west of New South Wales and Victoria. Big Lizzie has been preserved, and stands in a park in Red Cliffs, Victoria.
