Edgar Lee Masters (August 23, 1868 – March 5, 1950) was an American poet, biographer, and dramatist. He is the author of Spoon River Anthology, The New Star Chamber and Other Essays, Songs and Satires, The Great Valley, The Serpent in the Wilderness An Obscure Tale, The Spleen, Mark Twain: A Portrait, Lincoln: The Man, and Illinois Poems. In all, Masters published twelve plays, twenty-one books of poetry, six novels and six biographies, including those of Abraham Lincoln, Mark Twain, Vachel Lindsay, and Walt Whitman.

Masters was born in Garnett, Kansas where his father had briefly moved to set up a law practice.  The family soon moved back to his paternal grandparents' farm near Petersburg in Menard County, Illinois. In 1880, they moved to Lewistown, Illinois, where he attended high school and had his first publication in the Chicago Daily News. The culture around Lewistown, in addition to the town's cemetery at Oak Hill, and the nearby Spoon River were the inspirations for many of his works, most notably Spoon River Anthology, his most famous and acclaimed work.

Masters attended The Knox Academy from 1889–1890, a defunct preparatory program run by Knox College, but was forced to leave due to his family's inability to finance his education. After working in his father's law office, he was admitted to the Illinois bar and moved to Chicago.

Masters first published his early poems and essays under the pseudonym Dexter Wallace (after his mother's maiden name and his father's middle name) until the year 1903.  Masters began developing as a notable American poet in 1914, when he began a series of poems (this time under the pseudonym Webster Ford) about his childhood experiences in Western Illinois, which appeared in Reedy's Mirror, a St. Louis publication. In 1915, the series was bound into a volume and re-titled Spoon River Anthology. Years later, he wrote a memorable and invaluable account of the book’s background and genesis, his working methods and influences, as well as its reception by the critics, favorable and hostile, in an autobiographical article notable for its human warmth and general interest.

Mrs. Tim Lowry was most likely Katherine Anna Lowry, née Bulkley (1903-1977), wife of Northwestern University football star Timothy Goodrich Lowry and a champion golfer herself.
