[3] Highlighting Eigner's influence on the "Language School" of poetry, his work often appeared in the journal L=A=N=G=U=A=G=E, and was featured on the front page of its inaugural issue in February 1978.
[4] In the introduction to In the American Tree, Silliman identifies Eigner as a poet who has "transcended the problematic constraints" of Olson's speech-based projectivist poetics.
As he matured into an artist, Eigner overcame many physical obstacles and limitations to achieve a mastery over the material text, producing his typescripts on a 1940 Royal manual typewriter using only his right index finger and thumb.
[8] Perhaps the best realization to date of the idea of "composition by field" proposed by Charles Olson in his landmark essay "Projective Verse,"[9] the physical act of writing took tremendous effort from Eigner.
His work appeared in well over a hundred magazines and collections, most notably Origin, The Black Mountain Review, L=A=N=G=U=A=G=E, and in Don Allen's anthology The New American Poetry.
