Bergen-Belsen, near Hanover in Germany, was the first concentration camp to be liberated by British troops, on 15 April 1945. When soldiers of the 2nd Army arrived they found the camp littered with dead and dying prisoners. Around 60,000 starving people, many suffering from typhus and dysentery, required immediate aid.
And in 1895, while searching for argon, Scottish chemist Sir William Ramsay managed to isolate helium by treating a sample of cleveite with mineral acids. After treating the element with sulfuric acid, he noticed the same D3 absorption line. Ramsey sent samples of the gas to Sir William Crookes and Sir Norman Lockyer, who verified that it was helium. It was independently isolated from cleveite the same year by chemists Per Teodor Cleve and Abraham Langlet in Uppsala, Sweden, who were able to accurately determine its atomic weight.
