The change in the focus of the gallery led to a coalescence of group of intellectuals and artists who both sympathized with Stieglitz's aims and who themselves were invigorated by the atmosphere there. After the artistic success of the Matisse exhibit, the gallery took on a new life. On any given day, Stieglitz might have been surrounded by artists John Marin, Max Weber, Arthur Dove, Marsden Hartley or Marius de Zayas; authors and art critics Sadakichi Hartmann and Benjamin De Casseres; financial supporters Paul Haviland and Agnes Ernst Meyer; and editors and collaborators Joseph Keiley and John Kerfoot.
