The Administrative Assistant was in charge of the general supervision of the expenditure of United States National Museum (USNM) appropriations; preparing proposals for supplies; settlement of accounts; awarding contracts; supervision of non-scientific or specimen-related correspondence; general supervision of employees, assignments to duty, granting leaves of absence; and conducting boards of inquiry and investigations of complaints. The Administrative Assistant also acted as special agent and at times was appointed representative of the Museum and the Smithsonian at international expositions. Prior to 1902 the incumbent was known as Chief Clerk.
William V. Cox was designated as the Museum's first Chief Clerk in 1885. When he left the Museum in 1902 the title of the position was changed to Administrative Assistant and William deC. Ravenel was appointed to the post. By the time Ravenel retired in 1931, most of his duties had been assumed by the Associate Director, USNM, and the position of Administrative Assistant was removed from the Museum hierarchy.
