In 1897,
Congress created the
United States Copyright Office as a separate department of the Library of Congress to handle the administrative functions of copyright law. Solberg was widely supported to become the first head of the Office due to his growing reputation as a national authority on copyright (and due to some lobbying on his own part for the post). After being interviewed by President
William McKinley, Solberg was appointed by Librarian of Congress
John Russell Young and took office as the first
Register of Copyrights on July 22, 1897, with an annual salary of $3000 and a staff of 29 clerks. During his tenure as Register, Solberg played an active role in advancing United States copyright law. He advocated copyright reform and was instrumental in the passage of the
Copyright Act of 1909, one of the most significant revisions in United States copyright law. He was known as a champion for the rights of authors and supported relaxing the
registration and
deposit requirements of copyright law, consistent with the shift away from
copyright formalities in the
Berne Convention. Solberg also pushed for the United States to join the
Berne Convention. Thorvald Solberg retired as Register on April 21, 1930, his 78th birthday. He remains the longest-serving Register of Copyrights. ==Personal life==
