Heath Robinson, early 20th Century cartoonist. He's famous for his eccentric contraptions, usually constructed with bits of knotted string. They would definitely work in real life if you were to make them, I think.One day I'll try and make one.
Apparently he started off as a landscape painter, but only sold one painting, which was bought out of kindness, so he became a cartoonist and book illustrator as well.
Some books illustrated by him:
Bill the Minder
The Water Babies
One thing I really liked about his drawings was the use of black and white, inspired by Aubrey Beardsley. He also used tonal work and colour.
