9. Ludwig Mies van der Rohe "Skyscrapers reveal their bold structural pattern during construction. Only then does the gigantic steel web seem impressive. When the outer walls are put in place, the structural system, which is the basis of all artistic design, is hidden by a chaos of meaningless and trivial forms...Instead of trying to solve old problems with these old forms we should develop new forms from the very nature of the new problems. We can see the new structural principles most clearly when we use glass in place of the outer walls, which is feasible today since in a skeleton building these outer walls do not carry weight. The use of glass imposes new solutions.

11. Professor Erna Furman, pediatrician: "Friedl's teaching, the times spent drawing with her, are among the fondest memories of my life. The fact that it was Terezin made it more poignant but it would have been the same anywhere in the world … I learned lots of other things in camp too. Terezin had many world famous specialist in every field and most of them were glad to give lessons or seminars for bread (I was glad to give my bread for this better nourishment!). I learned philosophy, economics, Rorschach testing, etc. But I think Friedl was the only one who taught without ever asking for anything in return. She just gave of herself." from a letter to Elena Makarova, 1989
