Barbara Ringer (May 29, 1925 – April 9, 2009) was one of the lead architects of the 1976 Copyright Act. She spent much of her career lobbying Congress and drafting legislation that overhauled the 1909 Copyright Act. Ringer was also the first woman to serve as the Register of Copyrights in the United States Copyright Office. During her three decades with the United States Copyright Office, Ringer gained a reputation as an authority on copyright law.
The Copyright Act of 1976 is a United States copyright law and remains the primary basis of copyright law in the United States, as amended by several later enacted copyright provisions. The Act spells out the basic rights of copyright holders, codified the doctrine of "fair use", and for most new copyrights adopted a unitary term based on the date of the author's death rather than the prior scheme of fixed initial and renewal terms. It became Public Law number 94-553 on October 19, 1976; most parts of the law went into effect on January 1, 1978.
US Register of Copyrights Barbara Ringer took an active role in drafting the statute.
