Born in
Raymond,
Mississippi in 1895, the eldest of nine children, Lee was the daughter of Benjamin Floyd Lee, "a self-taught druggist" and son of a
planter, and Mary Maud (McWilliams) Lee, whose father was a physician. Three of her siblings died in infancy. Her parents encouraged her early interest in literature and art. When Muna was seven her family moved to
Hugo,
Oklahoma, where her father set up his store. It was in the heart of "Indian country", at a time when many whites were moving to Oklahoma. Lee returned to Mississippi at age 14 to attend Blue Mountain College (then scaled like a prep school). After a year and summer study at the
University of Oklahoma, she went on to the
University of Mississippi, where she graduated in 1913 at the age of eighteen. Lee published her first poem soon after. After college, she started working as a teacher in Oklahoma, then in Texas. By fall of 1916, she was teaching in
Tonkawa, Oklahoma, at a new junior college, University Preparatory School (now
Northern Oklahoma College). Through all these moves and her teaching, she kept writing and submitting poems to magazines. In 1916, she succeeded in getting several poems published in national literary magazines:
Poetry: A Magazine of Verse, Smart Set, Contemporary Verse, and
Others: A Magazine of the New Verse. Three of these were new magazines devoted to contemporary poetry. Her year of publication was crowned in September by her winning the first Lyric Prize of
Poetry magazine. Lee taught herself Spanish and got a job with the
United States Secret Service in
New York City, where she worked as a translator during
World War I. She translated confidential letters from Spanish, Portuguese and French. By this time she had already published two dozen poems in
Smart Set, and was its second-most frequent contributor. In New York, she quickly learned about the Pan American movements and began to explore Latin American literature. In 1918 she had poems published in
Pan American Poetry and
Pan-American Magazine. All were translated by
Nicaraguan poet
Salomón de la Selva, who was editor-in-chief of the poetry magazine). ==Marriage and family==
