1844–1916
A Swedish writer, journalist, politician, and peace activist, he devoted much of his life to arbitration and international understanding. His long campaign for peaceful solutions to conflict helped earn the 1908 Nobel Peace Prize.
After his father's death, Arnoldson left school young and went to work on the Swedish railways, eventually becoming a stationmaster. He later turned fully to public life as a writer, journalist, and politician, serving in the Swedish parliament in the 1880s.
He became one of Sweden's best-known advocates for peace, helping found the Swedish Peace and Arbitration Society and arguing that disputes between nations should be settled through negotiation rather than war. He also played a public role in debates around relations between Sweden and Norway, pressing for calm and compromise.
In 1908, Arnoldson shared the Nobel Peace Prize with Fredrik Bajer for their long work in the cause of peace. Remembered as both a public campaigner and a man of letters, he stands out as an early voice for international arbitration and nonviolent politics.
