- Raoul Gustaf Wallenberg (4 August 1912 – disappeared 17 January 1945) was a Swedish architect, businessman, diplomat, and humanitarian. He saved thousands of Jews in German-occupied Hungary during the Holocaust from German Nazis and Hungarian fascists during the later stages of World War II. While serving as Sweden’s special envoy in Budapest between July and December 1944, Wallenberg issued protective passports and sheltered Jews in buildings he declared as Swedish territory.
- Aluminium (Wikipedia)
Aluminium (Aluminum in North American English) is a chemical element; it has symbol Al and atomic number 13. Aluminium has a density lower than that of other common metals, about one-third that of steel. It has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, nonmagnetic, and ductile. It has one stable isotope, 27Al, which is highly abundant, making aluminium the twelfth-most common element in the universe. The radioactivity of 26Al, a more unstable isotope, leads to it being used in radiometric dating.
