De Stijl
Because of van Doesburg's pivotal role within De Stijl, the group did not survive. Individual members remained in contact, but De Stijl could not exist without a strong central character. Thus, it may be wrong to think of De Stijl as a close-knit group of artists. The members knew each other, but most communication took place by letter. For example, Mondrian and Rietveld never met in person.
