Eduardo Federico Newbery (February 17, 1878 in Buenos Aires – October 17, 1908 in Río de la Plata) was an Argentine odontologist and aerostat pilot.

His father, Ralph Lamartine Newbery Purcell, emigrated from Long Island, New York, and settled in Argentina after the American Civil War, in which he fought on the Union side of the Battle of Gettysburg and was recognized for his courage.

Eduardo was one of aviation pioneer Jorge Newbery's siblings (the others were Ernesto Purcell, Elena Rosa, Rodolfo León and María de los Dolores (twins), Elvira Teresa, Emma Catalina, Carlos Alfredo, Luis Alfredo, Juan Alberto Martín and Ana Eva).

His brother Jorge, however, was arguably his number one fan, and felt great respect and admiration for Eduardo.

Bradley also manned the aircraft on several air competitions in Argentina establishing new records of distance, endurance and altitude.
