also joined the Wisconsin Social Democratic Party, the name by which the Socialist Party of America was known in the state. Sandburg served as a secretary to Emil Seidel, socialist mayor of Milwaukee from 1910 to 1912. Carl Sandburg later remarked that Milwaukee was where he got his bearings and that the rest of his life had been "the unrolling of a scene that started up in Wisconsin". Sandburg met Lilian Steichen (1883-1977) at the Milwaukee Social Democratic Party office in 1907, and they married the next year in Milwaukee. Lilian's brother was the photographer Edward Steichen. Sandburg with his wife, whom he called Paula, raised three daughters. Their first daughter, Margaret, was born in 1911. The Sandburgs moved to Harbert, Michigan, and then to suburban Chicago, Illinois in 1912 after he was offered a job by a Chicago newspaper. They lived in Evanston, Illinois before settling at 331 South York Street in Elmhurst, Illinois, from 1919 to 1930. During the time, Sandburg wrote Chicago Poems (1916), Cornhuskers (1918), and Smoke and Steel (1920). In 1919 Sandburg won a Pulitzer Prize "made possible by a special grant from The Poetry Society" for his collection Cornhuskers. Sandburg also wrote three children's books in Elmhurst: Rootabaga Stories, in 1922, followed by Rootabaga Pigeons (1923), and Potato Face (1930). Sandburg also wrote Abraham Lincoln: The Prairie Years, a two-volume biography, in 1926, The American Songbag (1927), and a book of poems called Good Morning, America (1928) in Elmhurst. The Sandburg house at 331 South York Street in Elmhurst was demolished and the site is now a parking lot. The family moved to Michigan in 1930. Sandburg won the 1940 Pulitzer Prize for History for the four-volume The War Years, the sequel to his Abraham Lincoln, and a second Poetry Pulitzer in 1951 for Complete Poems. In 1945 he moved to Connemara, a rural estate in Flat Rock, North Carolina. Here he produced a little over a third of his total published work and lived with his wife, daughters, and two grandchildren. On February 12, 1959, in commemorations of the 150th anniversary of Abraham Lincoln's birth, Congress met in joint session to hear actor Fredric March give a dramatic reading of the Gettysburg Address, followed by an address by Sandburg. Sandburg supported the Civil Rights Movement and was the first white man to be honored by the NAACP with their Silver Plaque Award as
