Weir and many of his artist friends exhibited in Armory Show of 1913—an international show of over three hundred artists that boasted the largest attendance of an art exhibition in New York. Over 100,000 people saw the many works exhibited, and were introduced to new “modern” artists like Marcel Duchamp and Pablo Piscasso. With the success of the show, Weir realized that “these young artists are getting at the real thing, they are the ones to watch. Our work is a thing done.”

Nonetheless, this show was just one event in 1910s that marked Weir’s recognized stature as an artist. Critical acclaim ultimately brought Weir to the forefront of the American art establishment, culminating in his election in 1915 to the presidency of the National Academy and to membership in the American Academy of Arts and Letters, the Association of American Painters and Sculptors, the Board of Directors at the Metropolitan Museum of Art, his appointment to the National Commission on Fine Arts as “Painter Member” in 1916 and his receipt of honorary degrees from Princeton and Yale in 1916-17.

Weir died from heart disease on December 8, 1919. During his illness, he had been comforted by his time at the Branchville farm, where he would sit on the porch, observe the farm’s natural beauty, and reflect on his full life. As Weir wrote: “Really, I know not what I am best at. I believe I am a fisherman, dreamer and lover of nature…and if I lived to 120 I might become an artist.”
