IN: Camillo Golgi (Italian: [ka'millo 'goldZi]; 7 July 1843 - 21 January 1926) was an Italian physician and pathologist known for his works on the central nervous system. He studied medicine at the University of Pavia (where he later spent most of his professional career) between 1860 and 1868 under the tutelage of Cesare Lombroso. Inspired by pathologist Giulio Bizzozero, he pursued research in nervous system. His discovery of a staining technique called black reaction (sometimes called Golgi's method or Golgi's staining in his honour) in 1873 was a major breakthrough in neuroscience.

Central nervous system was difficult to study during Golgi's time because the cells were hard to identify. The available tissue staining techniques were useless for studying nervous tissue. While working as chief medical officer at the Hospital of the Chronically Ill, he experimented with metal impregnation of nervous tissue, using mainly silver (silver staining). In the early 1873, he discovered a method of staining nervous tissue that would stain a limited number of cells at random in their entirety. He first treated the tissue with potassium dichromate to harden it, and then with silver nitrate. Under microscope, the outline of the neuron became distinct from the surrounding tissue and cells. The silver chromate precipitate, as a reaction product, only selective stains some cellular components randomly, sparing other cell parts. The silver chromate particles create a stark black deposit on the soma (nerve cell body) as well as on the axon and all dendrites, providing an exceedingly clear and well-contrasted picture of neuron against a yellow background. This makes it easier to trace the structure of the nerve cells in the brain for the first time. Since cells are selective stained in black, he called the process la reazione nera ("the black reaction"), but today it is called Golgi's method or the Golgi stain. On 16 February 1873, he wrote to his friend Niccolo Manfredi: I am delighted that I have found a new reaction to demonstrate, even to the blind, the structure of the interstitial stroma of the cerebral cortex. His discovery was published in the Gazzeta Medica Italiani on 2 August 1873.

IN: The Bee Gees were a pop music group formed in 1958. Their lineup consisted of brothers Barry, Robin, and Maurice Gibb. The trio were successful for most of their decades of recording music, but they had two distinct periods of exceptional success: as a popular music act in the late 1960s and early 1970s, and as prominent performers of the disco music era in the mid-to-late 1970s. The group sang recognisable three-part tight harmonies; Robin's clear vibrato lead vocals were a hallmark of their earlier hits, while Barry's R&B falsetto became their signature sound during the mid-to-late 1970s and 1980s.

In an interview with Easy Mix radio host Tim Roxborough on 1 September 2009, Barry's 63rd birthday, Barry commented on future tours saying that "they will be back"; but in an agreement with Warner/Rhino they would not make an announcement at that time. On 7 September 2009, Robin disclosed to Jonathan Agnew that he had been in touch with Barry and that they had agreed that the Bee Gees would re-form and "perform again". Barry and Robin performed on the BBC's Strictly Come Dancing on 31 October 2009 and appeared on ABC-TV's Dancing with the Stars on 17 November 2009. On 15 March 2010, Barry and Robin inducted the Swedish group ABBA into the Rock and Roll Hall of Fame. On 26 May 2010, the two made a surprise appearance on the ninth-season finale of American Idol. On 20 November 2011 it was announced that Robin Gibb, at 61 years old, had been diagnosed with liver cancer, a condition he had become aware of several months earlier. He had become noticeably thinner in previous months and had to cancel several appearances due to issues with severe abdominal pain. On 13 February 2012, Robin joined British military trio the Soldiers for the Coming Home charity concert at the London Palladium, in support of injured servicemen. It was his first public appearance for almost five months and his final. On 14 April 2012, it was reported that Robin had contracted pneumonia in a Chelsea hospital and was in a coma. Although he came out of his coma on 20 April 2012, his condition deteriorated rapidly, and he died on 20 May 2012 of liver and kidney failure. With Robin's death, Barry became the last surviving Gibb brother, and the Bee Gees dissolved as a musical group.
QUESTION: What day was this for him
IN: Gallagher was born in Ballyshannon, County Donegal in 1948. His father Daniel was employed by the Irish Electricity Supply Board, who were constructing Cathaleen's Fall hydroelectric power station on the Erne River above the town. The family moved, first to Derry City, where his younger brother Donal was born in 1949. His mother, Monica, and the two boys then moved to Cork, where the brothers were raised.

In 2003, Wheels Within Wheels, a collection of acoustic tracks, was released posthumously by Gallagher's brother Donal Gallagher. Collaborators on this album included Bert Jansch, Martin Carthy, The Dubliners, Spanish flamenco guitarist Juan Martin and Lonnie Donegan. Many modern day musicians, including The Edge from U2, Slash of Guns N' Roses, Johnny Marr of the Smiths, Davy Knowles, Janick Gers of Iron Maiden, James Dean Bradfield of Manic Street Preachers, Glenn Tipton of Judas Priest, Vivian Campbell of Def Leppard, Gary Moore, Joe Bonamassa, cite Gallagher as an inspiration in their formative musical years. Brian May, lead guitarist of Queen, relates: "so these couple of kids come up, who's me and my mate, and say 'How do you get your sound Mr. Gallagher?' and he sits and tells us. So I owe Rory Gallagher my sound." In 2010, Gallagher was ranked No. 42 on Gibson.com's List of their Top 50 Guitarists of All Time. Gallagher was also listed on Rolling Stone magazine's list of the 100 Greatest Guitarists of All Time, ranked at 57th place. In April 2014, at the time of the auction of Gallagher's Patrick Eggle 'JS Berlin Legend' guitar, the BBC noted: "Eric Clapton credited him with 'getting me back into the blues'. The Rolling Stones wanted him to replace Mick Taylor and when Jimi Hendrix was asked how it felt to be the world's greatest guitarist, he is reported to have said: 'I don't know, go ask Rory Gallagher'" (but this may be a variant of an urban legend ).
