Robert Lee Frost (March 26, 1874 – January 29, 1963) was an American poet. He is highly regarded for his realistic depictions of rural life and his command of American colloquial speech. His work frequently employed settings from rural life in New England in the early twentieth century, using them to examine complex social and philosophical themes. A popular and often-quoted poet, Frost was honored frequently during his lifetime, receiving four Pulitzer Prizes for Poetry. For forty-two years, from 1921 to 1963, Frost spent almost every summer and fall teaching at the Bread Loaf School of English of Middlebury College, at the mountain campus at Ripton, Vermont.
