Joseph Beuys
One fascinating aspect of Joseph Beuys's personal history is the reason he consistently used felt and fat in his works. He is quoted as saying: "For me, fat was a great discovery, because it was the very material that could seem the most chaotic and indeterminate. I could use it with heat or cold, I could transform it with means that are not the traditional ones for sculpture- with temperature, for example. So I could turn the character of this fat from a chaotic and fluctuating condition to that of a rigid form... So I took an extreme position in sculpture and a material that was absolutely fundamental for life and not associated with art.”
