Birth and early career Brice was born in Sioux City, Iowa on March 30, 1889. His brother was Charles Frances Goldsborough. In 1910, he was serving in the United States Navy and living in Washington, D.C., and he was working as an electrician. He moved to Long Island and later to Manhattan. After serving two four-year terms in the Navy, he and Morris Titterington, the inventor of the ground induction compass, formed the Pioneer Instrument Company in 1919.

Brice also flew with Charles Augustus Lindbergh (1902-1974) aboard the Spirit of St. Louis in test flights from Curtiss Field as an "instrument expert" on May 13, 1927 for 10 minutes and May 15, 1927 for 15 minutes. Lindbergh's record breaking flight was on May 20–21, 1927. The crash On December 23, 1927 Frances Wilson Grayson with Brice H. Goldsborough as her navigator left from Curtis Field in New York for Harbour Grace, Newfoundland. Her plan was to leave from Newfoundland on a record setting transatlantic flight to London on Christmas day. Her plane, The Dawn was to be flown by Oskar Omdal, a lieutenant in the Norwegian Navy. Grayson may have planned to fly the plane in shifts with him. Goldsborough would have been the navigator and Frank Koehler was to be the radio operator. Her plane never reached Newfoundland and sank in the water. There were several accounts of receiving radio messages from the plane when it was in distress. The bodies and the airplane were never recovered. Family Brice's son was Frank Goldsborough (1910–1930), who was a record-setting aviator who also died in a crash.
