I believe that many people don't know or remember them because nowadays you are taught different things at school to prepare you for a life of work, and functioning in a society which somehow respects you most if you have loads of money. Too bad, because art can be so much more gratifying than a huge car, a huge house and a big bank account. I know what I'm talking about, I'm an artist living on very little money and doing volunteer work at the Printing Shop of the Gutenberg Museum in Mainz, Germany...:-)
