The first USS Jeannette was originally HMS Pandora, a Philomel-class gunvessel of the Royal Navy, and was purchased in 1875 by Sir Allen Young for his arctic voyages in 1875-1876. The ship was purchased in 1878 by James Gordon Bennett, Jr., owner of the New York Herald; and renamed Jeannette. Bennett was an Arctic enthusiast, and he obtained the cooperation and assistance of the government in fitting out an expedition to the North Pole through the Bering Strait. 
Jeannette departed San Francisco on 8 July 1879, the Secretary of the Navy having added to her original instructions the task of searching for the long-overdue Under Lt. Cdr. DeLong's direction the ship sailed across the Chukchi Sea and sighted Herald Island on 4 September. Soon afterward she was caught fast in the ice pack near Wrangel Island at 71°35'N 175°6'E
In May 1881, two islands were discovered and named Jeannette and Henrietta. In June, Bennett Island was discovered and claimed for the U.S. On the night of 12 June, the pressure of the ice finally began to crush Jeannette when they had reached 77°15'N 154°59'E. DeLong and his men unloaded provisions and equipment onto the ice pack and the ship sank the following morning.
