a National Arts Club exhibition in 1904, through which he befriended the painters William Glackens, Robert Henri, and John French Sloan. He exhibited with them in 1908 at Macbeth Galleries, along with George Luks, Everett Shinn, and Arthur B. Davies, a group collectively known after the show as The Eight. Glackens in particular became a lifelong friend. Despite poor health that hindered his work, Prendergast continued to show in major exhibitions throughout the remainder of his life. Important collectors like Albert Barnes and Ferdinand Howald became his patrons after his shows at the Carroll Gallery and the Daniel Gallery. His seven works at the landmark Armory Show of 1913 presented examples of his stylistic maturity. Seen in company with the most adventurous examples of Post-Impressionism and Fauvism, "his critical reception grew more favorable in [the] immediate aftermath [of that exhibition.]" In 1916, he participated in the "Fifty at Montross" show at the Montross Gallery, which also included works by Cézanne, Matisse, Seurat, and Van Gogh. His work was the subject of a retrospective at Joseph Brummer Gallery in 1921, but the Metropolitan Museum of Art declined to host a Prendergast memorial retrospective after his death in 1924; at that time, his art was still seen as too demanding and advanced for the Metropolitan's trustees. His first New York memorial exhibition was held ten years later at the Whitney Museum of American Art. "The Eight" Prendergast exhibited at the Macbeth Galleries in 1908 with the short-lived association of artists known as "The Eight" because he supported their protest against the academic bias and restrictive exhibition policies of the powerful, conservative National Academy of Design. He believed in a "no jury, no prizes" openness that would allow independent or unconventional artists greater opportunities to find a wider, appreciative audience for their work. This controversial exhibition, which acquired legendary status in American art history, is seen as a seminal moment in the public response to Ashcan realism, as that form of gritty urban representational art was the style practiced by five of the participants (Henri, Sloan, Luks, Shinn, and Glackens), but Prendergast has nothing in common, in style or content, with that school of painting. Prendergast was far more a Modernist than any of the other seven members of The Eight. His ties to The Eight did not necessarily help his reputation in the long run: "Prendergast's irrevocable association with The Eight left
