Salomon August Andrée, during his lifetime most often known as S. A. Andrée, was a Swedish engineer, physicist, aeronaut and polar explorer who died while leading an attempt to reach the Geographic North Pole by hydrogen balloon. The balloon expedition was unsuccessful in reaching the Pole and resulted in the deaths of all three of its participants.
