Anna Thilda May “May” Swenson (28 May 1913– 4 December 1989) was an American poet and playwright. She is considered one of the most important and original poets of the 20th century, as often hailed by the noted critic Harold Bloom. The first child of Margaret and Dan Arthur Swenson, she grew up as the eldest of ten children in a Mormon household where Swedish was spoken regularly and English was a second language. As a lesbian, she was somewhat shunned by her family for religious reasons. Much of her later poetry works were devoted to children. She also translated the work of contemporary Swedish poets, including the selected poems of Nobel laureate Tomas Tranströmer.
