Robert James Fischer (March 9, 1943 - January 17, 2008) was an American chess grandmaster and the eleventh World Chess Champion. Many consider him to be the greatest chess player of all time. Bobby Fischer showed great skill in chess from an early age; at 13, he won a brilliancy known as "The Game of the Century". At age 14, he became the US Chess Champion, and at 15, he became both the youngest grandmaster up to that time and the youngest candidate for the World Championship.
Sources implying that Paul Nemenyi, a Hungarian-Jewish mathematician and physicist and an expert in fluid and applied mechanics, was Fischer's biological father were first made public in a 2002 investigation by Peter Nicholas and Clea Benson of The Philadelphia Inquirer. Throughout the 1950s, the FBI investigated Regina and her circle for her alleged communist sympathies, as well as her previous life in Moscow. FBI files identify Paul Nemenyi as Bobby Fischer's biological father, showing that Hans-Gerhardt Fischer never entered the United States, having been refused admission by US immigration officials due to his alleged Communist sympathies. Not only were Regina and Nemenyi reported to have had an affair in 1942, but Nemenyi made monthly child support payments to Regina and paid for Bobby's schooling until his own death in 1952. Nemenyi had lodged complaints with social workers, saying he was concerned about the way that Regina was raising Bobby, to the point that, on at least one occasion, Nemenyi broke down in tears. Later on Bobby told the Hungarian chess player Zita Rajcsanyi that Paul Nemenyi would sometimes show up at the family's Brooklyn apartment and take him on outings. After Paul Nemenyi died in 1952, Regina Fischer wrote a letter to Nemenyi's first son, Peter, asking if Paul had left money for Bobby in his will: Bobby was sick 2 days with fever and sore throat and of course a doctor or medicine was out of the question. I don't think Paul would have wanted to leave Bobby this way and would ask you most urgently to let me know if Paul left anything for Bobby. On one occasion, Regina told a social worker that the last time she had ever seen Hans-Gerhardt Fischer was in 1939, four years before Bobby was born. On another occasion, she told the same social worker she had traveled to Mexico to see Hans-Gerhardt in June 1942 and that Bobby was conceived during that meeting. According to Bobby Fischer's brother-in-law, Russell Targ (who was married to Joan), Regina concealed the fact that Nemenyi was Bobby's father because she wanted to avoid the stigma of an out-of-wedlock birth.

What is the significance?

Regina and Nemenyi reported to have had an affair in 1942, but Nemenyi made monthly child support payments

Al-Husayn ibn Ali ibn Abi Talib (Arabic: lHsyn bn 'ly bn 'by Tlb; 10 October 625 - 10 October 680) (3 Sha'aban AH 4 (in the ancient (intercalated) Arabic calendar) - 10 Muharram AH 61) (his name is also transliterated as Husayn ibn 'Ali, Husain, Hussain and Hussein), was a grandson of the Islamic Nabi (Arabic: nabiy, Prophet) Muhammad, and son of Ali ibn Abi Talib (the first Shia Imam and the fourth Rashid caliph of Sunni Islam), and Muhammad's daughter, Fatimah. He is an important figure in Islam as he was a member of the Bayt (Arabic: bayt, Household) of Muhammad, and Ahl al-Kisa' (Arabic: 'ahl lkisa, People of the Cloak), as well as being the third Shia Imam.
According to the Shi'ah, Husayn was the third Imam for a period of ten years after the death of his brother Hasan in CE 669, all of this time but the last six months coinciding with the caliphate of Mu'awiyah. After the peace treaty with Hasan, Mu'awiyah set out with his troops to Kufa, where at a public surrender ceremony Hasan rose and reminded the people that he and Husayn were the only grandsons of Muhammad, and that he had surrendered the reign to Mu'awiyah in the best interest of the community: "O people, surely it was God who led you by the first of us and Who has spared you bloodshed by the last of us. I have made peace with Mu'awiyah, and I know not whether haply this be not for your trial, and that ye may enjoy yourselves for a time." declared Hasan. In the nine-year period between Hasan's abdication in 41/660 and his death in 49/669, Hasan and Husayn retired in Medina trying to keep aloof from political involvement for or against Muawiyah. Shi'ite feelings, however, though not visible above the surface, occasionally emerged in the form of small groups, mostly from Kufa, visiting Hasan and Husayn asking them to be their leaders - a request to which they declined to respond. Even ten years later, after the death of Hasan, when Iraqis turned to his younger brother, Husayn, concerning an uprising, Husayn instructed them to wait as long as Muawiyah was alive due to Hasan's peace treaty with him. Later on, however, and before his death, Muawiyah named his son Yazid as his successor.

Who was surrendering?

Hasan rose and reminded the people that he and Husayn were the only grandsons of Muhammad, and that he had surrendered

Asa Gray (November 18, 1810 - January 30, 1888) is considered the most important American botanist of the 19th century. His Darwiniana was considered an important explanation of how religion and science were not necessarily mutually exclusive. Gray was adamant that a genetic connection must exist between all members of a species. He was also strongly opposed to the ideas of hybridization within one generation and special creation in the sense of its not allowing for evolution, as he felt evolution was guided by a Creator.
Despite no longer having the burden of his professorial and garden duties, by the late 1870s the burden of maintaining himself as the pillar of American botany prevented Gray from the progress he desired on Synoptical Flora of North America, the follow-on to Flora of North America. This burden consisted of the fact that other scientists often only accepted Gray's word on a botanical matter, and the number of incoming specimens to identify was increasing vastly: numbers had to be assigned to them, collectors needed to be corresponded with, and preliminary papers had to be published. By the early 1880s, Gray's home was the center of everything to do with botany in America. Every aspiring botanist came to see him, even if just to look at him through his window. After turning over his non-research duties to Sargent, Goodale, Farlow, and Watson, Gray concentrated more on research and writing, especially on plant taxonomy, as well as lecturing around the country, largely promoting Darwinian ideas. Many of his lectures during this time were given at the Yale Divinity School. Liberty Hyde Bailey worked as Gray's herbarium assistant for two years during 1883-1884. In spring 1887 Gray and his wife made their last trip to Europe, this one for six months from April-October, primarily to see Hooker. Gray received the following advanced degrees: honorary degree of Master of Arts (1844) and Doctor of Laws (1875) from Harvard, and Doctor of Laws from Hamilton College (New York) (1860), McGill University (1884), and the University of Michigan (1887).

What did Gray accomplish later?
Gray concentrated more on research and writing, especially on plant taxonomy,
