It is generally accepted wisdom that the first jazz band to ever play at the White House was Ray Miller's Orchestra (including Miff Mole and Frank Trumbauer), on October 17, 1924 [see Edward Allan Faine's article in Vintage Jazz Mart].
But is this really correct ?
New York Morning Telegraph, May 26, 1920, p.4:
HICKMAN'S BAND AT THE WHITE HOUSE - Art Hickman's Jazz Orchestra will stop over at Washington on its journey East and give a concert at the White House before Senators and Congressmen who are to be gathered there on the night of June 4. It is planned to have the President hear a few of the numbers. San Francisco, by the way, is to give Hickman a rousing send-off. He has been the best advertiser of San Francisco since the earthquake by regaling it with his music at the St. Francis Hotel night after night. A number of prominent citizens who have greatly admired the music of the Hickman orchestra are giving him a public dinner on Friday night. A golden baton, properly inscribed, will be presented on that occasion.
