Thomas Francis Bayard (October 29, 1828 – September 28, 1898) was an American lawyer, politician, and diplomat from Wilmington, Delaware.
 A Democrat, he served three terms as United States Senator from Delaware and made three unsuccessful bids for the Democratic nomination for President of the United States.
 In 1885, President Grover Cleveland appointed him Secretary of State.
 After four years in private life, he returned to the diplomatic arena as Ambassador to the United Kingdom. Work–life interface
Work–life interface is the intersection of work and private life.
 There are many aspects of one's personal life that can intersect with work including family, leisure, and health.
 Work–life interface is bidirectional; for instance, work can interfere with private life, and private life can interfere with work.
 This interface can be adverse in nature (e.g., work-life conflict) or can be beneficial (e.g., work-life enrichment) in nature. Wanyan Chonghou
Wanyan Chonghou (October, 1824 – 1893) was a Qing dynasty official and diplomat, said to have been a lineal descendant of the Imperial House of the Jin dynasty (1115–1234).
 Graduating as juren, he became a Taotai in Zhili in 1858, and in 1861 Superintendent of Trade for the three northern ports, to reside at Tianjin.
 He was occupying this post when the Tianjin Massacre occurred on the 21st June, 1870.
 Of all actual connivance at or participation in this tragedy he was doubtless innocent, though with a stronger man in power it would most likely not have taken place.
 He was sent to France with a letter of apology, which he handed to Adolphe Thiers, being undoubtedly the first Chinese official of any rank who had ever visited the west.
 On his return in 1872 he was appointed Vice President of the Board of War and a member of the Zongli Yamen.
 In 1874 he was Vice President of the Board of Revenue, and in 1876 he was sent as acting General of Shengjing, replacing his brother, Wanyan Chongshi, who had died that year.
 In 1878 he proceeded as Ambassador to St. Petersburg, and negotiated the Treaty of Livadia, by which a large portion of Ili was ceded to Russia.
 In 1880 he was denounced by Li Hung-chang and Zuo Zongtang, nominally for returning without leave; and also by the then Censor Zhang Zhidong for having exceeded his powers.
 He was cashiered and arrested, and finally sentenced to death.
 For some time it was feared that he would lose his head.
 The foreign Ministers did all in their power to effect his release, but in vain.
 At length Queen Victoria interposed on his behalf; and in response to her letter he was pardoned, upon which he retired into private life.
 He died in 1893, of creeping paralysis; and in 1894 his rank was restored, less two grades.
 He was extremely courteous to foreigners, and was much liked by all foreign officials with whom he was thrown into contact. The Private Life of Louis XIV
The Private Life of Louis XIV or Liselotte of the Palatinate (German:Liselotte von der Pfalz) is a 1935 German historical film directed by Carl Froelich and starring Renate Müller, Eugen Klöpfer and Maria Krahn.
 The film's English language release title is a reference to the hit British film "The Private Life of Henry VIII" (1933). The Private Life of the Kingfisher
The Private Life of the Kingfisher (styled in its opening titles as "The private life of the KINGFISHER), made in 1966 and screened in 1967 as episode 144 of the nature series "Look", was the first BBC natural history film to be shown in colour. Une double famille
Une double famille ("A Second Home") is a lengthy short story by Honoré de Balzac, which first appeared in 1830 under the title "La femme vertueuse" ("The Virtuous Woman").
 It was subsequently published in 1832 by Mame et Delaunay as part of Balzac's "Scènes de la vie privée" ("Scenes from Private Life").
 In 1835 it appeared, in an edition by Madame Béchet, in the collection "Études de mœurs" ("Studies of Manners").
 The novel only acquired its present title in 1842, when the fifth edition appeared in Volume I of the "Scenes from Private Life", which was also the first volume of Balzac's "La Comédie humaine".
