De Bray was influenced by Joseph-René Bellot’s service on an English expedition as a volunteer for the Franklin Search with Sir Edward Belcher aboard HMS Resolute. He served in the Arctic from 1852 to 1854, commanded a number of sledge expeditions, and left the Resolute shortly before it was abandoned. He was a friend of Jules Verne who used De Bray’s Arctic knowledge in a novel based on the Franklin Search.
