Alonzo Fields (April 10, 1900 – March 22, 1994)[2] was an American butler who served at the White House for twenty-one years under presidents Hoover, Roosevelt, Truman and Eisenhower.

While the attitudes of most southern U.S. senators would not begin to change until the advent of the Civil Rights Movement, Roosevelt took it upon himself to remove racial tensions among the house staff by making it all black.

[2][4][5] After his retirement in 1960, Fields published My 21 Years in the White House, in which he wove together his private papers and cryptic journals, written while serving, with his recollections.

Although restrained, his memoir nonetheless provides a uniquely intimate primary source account of the U.S. presidents he served, several who came to trust Fields as a close personal friend.

[3][6] Historians, such as David McCullough in his 1992 biography Truman, continue to consult Fields' memoirs when constructing accounts of the presidents he served.
