Biography

Aristide Briand (1862-1932) was a French politician (served 11 terms as Prime Minister) and lawyer. He played a major role in international relations after WW1 and in 1926 alongside Gustave Streseman, he was awarded the Nobel peace prize in honour of his work as minister of foreign affairs for his role in the reconciliation of French and German relations (Locarno 1925).

His dream of global safety around the world, helped by the SDN (Societé des Nations/ League of Nations), was advanced by the signing of the Brian-Kellog pact with the American Frank Billings Kellogg in 1928 that would outlaw wars. In 1929, he launched a new project of a European Nation known as the Briand plan for Europe. In September 1930, a resolution is signed and accepted by 45 countries. It is most likely that Aristide Briand received this watch as a gift during one of his many trips to the SDN in Geneva during that year.
