Answer the question at the end by quoting:

Marc Zakharovich Chagall ( sh@-GAHL; born Moishe Zakharovich Shagal; 6 July [O.S. 24 June] 1887 - 28 March 1985) was a Russian-French artist of Belarusian Jewish origin. An early modernist, he was associated with several major artistic styles and created works in virtually every artistic format, including painting, book illustrations, stained glass, stage sets, ceramic, tapestries and fine art prints. Art critic Robert Hughes referred to Chagall as "the quintessential Jewish artist of the twentieth century" (though Chagall saw his work as "not the dream of one people but of all humanity"). According to art historian Michael J. Lewis, Chagall was considered to be "the last survivor of the first generation of European modernists".
Goodman notes that during this period in Russia, Jews had two basic alternatives for joining the art world: One was to "hide or deny one's Jewish roots". The other alternative--the one that Chagall chose--was "to cherish and publicly express one's Jewish roots" by integrating them into his art. For Chagall, this was also his means of "self-assertion and an expression of principle."  Chagall biographer Franz Meyer, explains that with the connections between his art and early life "the hassidic spirit is still the basis and source of nourishment for his art." Lewis adds, "As cosmopolitan an artist as he would later become, his storehouse of visual imagery would never expand beyond the landscape of his childhood, with its snowy streets, wooden houses, and ubiquitous fiddlers... [with] scenes of childhood so indelibly in one's mind and to invest them with an emotional charge so intense that it could only be discharged obliquely through an obsessive repetition of the same cryptic symbols and ideograms... "  Years later, at the age of 57 while living in the United States, Chagall confirmed this when he published an open letter entitled, "To My City Vitebsk":  Why? Why did I leave you many years ago? ... You thought, the boy seeks something, seeks such a special subtlety, that color descending like stars from the sky and landing, bright and transparent, like snow on our roofs. Where did he get it? How would it come to a boy like him? I don't know why he couldn't find it with us, in the city--in his homeland. Maybe the boy is "crazy", but "crazy" for the sake of art. ...You thought: "I can see, I am etched in the boy's heart, but he is still 'flying,' he is still striving to take off, he has 'wind' in his head." ... I did not live with you, but I didn't have one single painting that didn't breathe with your spirit and reflection.

How old was he when this happened

IN: Sherlock Holmes () is a fictional private detective created by British author Sir Arthur Conan Doyle. Referring to himself as a "consulting detective" in the stories, Holmes is known for his proficiency with observation, forensic science, and logical reasoning that borders on the fantastic, which he employs when investigating cases for a wide variety of clients, including Scotland Yard. First appearing in print in 1887 (in A Study in Scarlet), the character's popularity became widespread with the first series of short stories in The Strand Magazine, beginning with "A Scandal in Bohemia" in 1891; additional tales appeared from then until 1927, eventually totalling four novels and 56 short stories. All but one are set in the Victorian or Edwardian eras, between about 1880 and 1914.

Details about Sherlock Holmes's life, except for the adventures in the books, are scarce in Conan Doyle's original stories. Nevertheless, mentions of his early life and extended family paint a loose biographical picture of the detective.  An estimate of Holmes's age in "His Last Bow" places his year of birth at 1854; the story, set in August 1914, describes him as sixty years of age. His parents are not mentioned in the stories, although Holmes mentions that his "ancestors" were "country squires". In "The Adventure of the Greek Interpreter", he claims that his grandmother was sister to the French artist Vernet, without further clarifying whether this was Claude Joseph, Carle, or Horace Vernet. Holmes's brother Mycroft, seven years his senior, is a government official who appears in "The Adventure of the Greek Interpreter", "The Final Problem", and "The Adventure of the Bruce-Partington Plans" and is mentioned in "The Adventure of the Empty House". Mycroft has a unique civil service position as a kind of human database for all aspects of government policy. He lacks Sherlock's interest in physical investigation, however, preferring to spend his time at the Diogenes Club.  Holmes says that he first developed his methods of deduction as an undergraduate; his earliest cases, which he pursued as an amateur, came from fellow university students. A meeting with a classmate's father led him to adopt detection as a profession, and he spent six years after university as a consultant before financial difficulties led him to accept John H. Watson as a fellow lodger in 1881 (when the first published story, A Study in Scarlet, begins).  The two take lodgings at 221B Baker Street, London, an apartment at the upper (north) end of the street, up seventeen steps.

Is this about the writer's family and early life?
