History.
President Abraham Lincoln signed legislation creating the Secret Service on April 14, 1865, the day of his assassination. It was commissioned on July 5, 1865, in Washington, D.C., as the "Secret Service Division" of the Department of the Treasury. After being appointed by President Andrew Johnson, William P. Wood was sworn in as the first chief of the Secret Service on July 5, 1865 by Secretary of the Treasury Hugh McCulloch.
When the Secret Service was established, its head was called the chief of the Secret Service. In 1965, the title was changed to the director of the Secret Service, four years into the term of James Joseph Rowley (1961–1973). The longest serving head of the Secret Service was William H. Moran, who served under five presidents from 1917 to 1936.
On March 27, 2013, President Barack Obama appointed Julia Pierson to be the twenty-third director of the Secret Service. She became the first female director of the agency. On October 1, 2014, the Secret Service leadership changed to Director Joseph Clancy, a retired agent who formerly led the Presidential Protective Division. On March 4, 2017, Director Joseph Clancy retired, leaving the position vacant until a replacement was nominated by President Donald Trump. Meanwhile, William J. Callahan served as Acting Director of the United States Secret Service from March 4, 2017 to April 25, 2017. Randolph Alles, former acting deputy commissioner of the U.S. Customs and Border Protection, was appointed director by President of the United States Donald Trump.
