This photograph of Wilson Jackson with President Warren G. Harding and First Lady Florence Kling Harding's dogs O'Boy and Laddie Boy on the South Lawn of the White House was taken by the National Photo Company circa 1921. Jackson served as a messenger and caretaker of the White House dogs from 1907 to 1927.

In this photograph, taken on April 2, 1923 by Herbert E. French of the National Photo Company, children pose for a picture with Laddie Boy, the Harding family pet Airedale terrier, during the annual White House Easter Egg Roll. Wilson Jackson, the master of the hounds, can be seen handling Laddie Boy's leash. Laddie Boy "hosted" the Easter Egg Roll that year while the Hardings were away in Georgia. Dating back to 1878, the Easter Egg Roll is a cherished springtime tradition in Washington, D.C., with children and their families gathering to enjoy festivities on the South Lawn. This photograph is from the Herbert E. French Collection at the Library of Congress, which captured life in Washington, D.C., from the Wilson to the Hoover administrations.
