Edward Rowland Sill was born at Windsor, Connecticut, in 1841. In 1861 he was graduated from Yale and shortly thereafter his poor health compelled him West. After various unsuccessful experiments, he drifted into teaching, first in the high schools in Ohio, later in the English department of the University of California. His uncertain physical condition added to his mental uncertainty. Unable to ally himself either with the lethargic, conservative forces whom he hated or with the radicals whom he distrusted, Sill became an uncomfortable solitary; half rebellious, half resigned. During the last decade of his life, his brooding seriousness was less pronounced, a lighter irony took the place of his dark reflections.

The Hermitage, his first volume, was published in 1867, a later edition (including later poems) appearing in 1889. His two posthumous books are Poems (1887) and Hermione and Other Poems (1899).

Sill died, after bringing something of the Eastern culture to the West, in 1887.
