The National Academy of Sciences and National Academy of Engineering have issued a call for nominations for the Gibbs Brothers Medal recognizing outstanding contributions to naval architecture and marine engineering.

The prize was established in 1963 by William Francis Gibbs, a member of the National Academy of Sciences, and his brother, Frederic H. Gibbs. Nominees should be individuals whose careers have been primarily focused on work in the U.S. Past recipients demonstrate a wide range of accomplishments, including contributions to naval warships, containerships, submarines, propellers, offshore platforms, classification systems, and many more.

Recent recipients include naval architect Robert G. Keane, Jr., engineer Keith W. Tantlinger, and engineer Donald Liu.

The medal recipient receives $20,000, an illuminated scroll and vermeil medal, and expenses to attend the presentation ceremony at the NAS Annual Meeting in Washington, D.C., on April 30, 2017.

Nominations must be submitted online and are due by Oct. 3. Questions about the nomination process should be directed to Deborah Young at the National Academy of Engineering.
