William Carlos Williams (September 17, 1883 – March 4, 1963) was an American poet and physician closely associated with modernism and imagism. His Spring and All (1923) was written in the wake of T. S. Eliot's The Waste Land (1922). In his five-volume poem Paterson (1946–1958), he took Paterson, New Jersey as "my 'case' to work up. It called for a poetry such as I did not know, it was my duty to discover or make such a context on the 'thought.'" Some of his best known poems, "This Is Just to Say" and "The Red Wheelbarrow", are reflections on the everyday. Other poems reflect the influence of the visual arts. He, in turn, influenced the visual arts; his poem "The Great Figure" inspired the painting I Saw the Figure 5 in Gold by Charles Demuth. Williams was awarded a posthumous Pulitzer Prize for Poetry for Pictures from Brueghel and Other Poems (1962).
Williams practiced both pediatrics and general medicine. He was affiliated with Passaic General Hospital, where he served as the hospital's chief of pediatrics from 1924 until his death. The hospital, which is now known as St. Mary's General Hospital, paid tribute to Williams with a memorial plaque that states "We walk the wards that Williams walked".
