Delesio Antonio Berni was an Argentine figurative artist. He is associated with the movement known as Nuevo Realismo, a Latin American extension of social realism. His work, including a series of Juanito Laguna collages depicting poverty and the effects of industrialization in Buenos Aires, has been exhibited around the world.

Edward Frederick Lindley Wood, 1st Earl of Halifax, KG, OM, GCSI, GCMG, GCIE, TD, PC, styled The 1st Baron Irwin from 1925 until 1934 and The 3rd Viscount Halifax from 1934 until 1944, was a senior British Conservative politician of the 1930s. He held several senior ministerial posts during this time, most notably those of Viceroy of India from 1925 to 1931 and of Foreign Secretary between 1938 and 1940. He was one of the architects of the policy of appeasement of Adolf Hitler in 1936–38, working closely with Prime Minister Neville Chamberlain. However, after the German occupation of Czechoslovakia in March 1939 he was one of those who pushed for a new policy of attempting to deter further German aggression by promising to go to war to defend Poland.

On Chamberlain's resignation early in May 1940, Halifax effectively declined the position of Prime Minister as he felt that Churchill would be a more suitable war leader. A few weeks later, with the Allies facing apparently catastrophic defeat and British forces falling back to Dunkirk, Halifax favoured approaching Italy to see if acceptable peace terms could be negotiated.

The Battle of Tannenberg was fought between Russia and Germany between 26 and 30 August 1914, the first month of World War I. The battle resulted in the almost complete destruction of the Russian Second Army and the suicide of its commanding general, Alexander Samsonov. A series of follow-up battles destroyed most of the First Army as well and kept the Russians off balance until the spring of 1915. The battle is particularly notable for fast rail movements by the Germans, enabling them to concentrate against each of the two Russian armies in turn, and also for the failure of the Russians to encode their radio messages. It brought considerable prestige to Field Marshal Paul von Hindenburg and his rising staff-officer Erich Ludendorff.

Although the battle actually took place near Allenstein, Hindenburg named it after Tannenberg, 30 km to the west, in order to avenge the defeat of the Teutonic Knights 500 years earlier at the Battle of Grunwald by Poland-Lithuania.
