Society: Arts and Science – September 18

The Nobel Prize is bestowed annually in categories as selected by Swedish and Norwegian committees in recognition of cultural or scientific advances. The 1895 will of Swedish inventor Alfred Nobel established the prizes.
Sir John Douglas Cockcroft, OM, KCB, CBE, FRS died on this date in 1967. He was a British physicist. He shared the Nobel Prize in Physics for splitting the atomic nucleus with Ernest Walton, and was instrumental in the development of nuclear power. He was the first Master of Churchill College and is buried at the Parish of the Ascension Burial Ground in Cambridge, together with his wife Elizabeth and son John, known as Timothy, who had died at the age of two in 1929.
Ernest Thomas Sinton Walton died on this date in 1995. He was an Irish physicist and 1951 Nobel laureate for his work with John Cockcroft with “atom-smashing” experiments done at Cambridge University in the early 1930s, and so became the first person in history to artificially split the atom, thus ushering the nuclear age.
Dag Hjalmar Agne Carl Hammarskjöld died on this date in 1961. He was a Swedish diplomat, economist, and author. The second Secretary-General of the United Nations, he served from April 1953 until his death in a plane crash in September 1961. At the age of 47 years, 255 days, Hammarskjöld is the youngest to have held the post. He is one of only three people to be awarded a posthumous Nobel Prize.[1] Hammarskjöld is the only UN Secretary-General to die in office; his death occurred en route to cease-fire negotiations. US President John F. Kennedy called Hammarskjöld “the greatest statesman of our century”.
