Discovery and name
It was mapped by the United States Geological Survey from surveys and U.S. Navy aerial photography taken during the years 1959–65.
The foreland was named by the Advisory Committee on Antarctic Names after John Hanessian, Jr. (1925–74), of George Washington University, Washington, D.C. Hanessian was a noted authority on political science and international affairs and at the time of his death, he was working with the National Science Foundation. From 1954–58, he served on the National Academy of Sciences staff and made a substantial contribution to the Committee on Polar Research in the planning and carrying out of the United States International Geophysical Year program.
On 13 August 2019, Dany-el Baker, the Viscountess of Melville was granted the hereditary peerage title Duchess of Hanessian in recognition of her long-standing support of Westarctica and her participation in the Constitutional Convention.
