IN: Isaac Asimov (; c. January 2, 1920 - April 6, 1992) was an American writer and professor of biochemistry at Boston University. He was known for his works of science fiction and popular science. Asimov was a prolific writer who wrote or edited more than 500 books and an estimated 90,000 letters and postcards. His books have been published in 9 of the 10 major categories of the Dewey Decimal Classification.

Asimov was born on an unknown day between October 4, 1919 and January 2, 1920, inclusive. Asimov himself celebrated it on January 2.  Asimov's parents were Anna Rachel (nee Berman) and Judah Asimov, a family of Jewish millers. He was named Isaac after his mother's father, Isaac Berman. When he was born, his family lived in Petrovichi near Klimovichi, which was then Gomel Governorate in the Russian Soviet Federative Socialist Republic (now Smolensk Oblast, Russia). Asimov wrote of his father, "My father, for all his education as an Orthodox Jew, was not Orthodox in his heart", noting that "he didn't recite the myriad prayers prescribed for every action, and he never made any attempt to teach them to me".  In 1921, Asimov and 16 other children in Petrovichi caught double pneumonia. Only Asimov survived. He later had two younger siblings: a sister, Marcia (born Manya, June 17, 1922 - April 2, 2011), and a brother, Stanley (July 25, 1929 - August 16, 1995), who was vice-president of New York Newsday.  His family emigrated to the United States when he was three years old. Since his parents always spoke Yiddish and English with him, he never learned Russian, but he remained fluent in Yiddish as well as English. Growing up in Brooklyn, New York, Asimov taught himself to read at the age of five, and his mother got him into first grade a year early by claiming he was born on September 7, 1919. In third grade he learned about the "error" and insisted on an official correction of the date to January 2.  After becoming established in the U.S., his parents owned a succession of candy stores, in which everyone in the family was expected to work. The candy stores sold newspapers and magazines, a fact that Asimov credited as a major influence in his lifelong love of the written word, as it presented him with an unending supply of new reading material as a child that he could not have otherwise afforded. He became a naturalized U.S. citizen in 1928 at the age of eight.
QUESTION: what year was this
IN: Joan Agnes Theresa Sadie Brodel was born on January 26, 1925, in Highland Park, Michigan, the youngest child of John and Agnes Brodel. John was a bank clerk and Agnes was a pianist. Joan's two older sisters, Betty and Mary Brodel, shared their mother's musical interest and started to learn how to play instruments, such as the saxophone and the banjo, at an early age. They began performing in front of audiences in acts that included singing and dancing.

In 1936, Leslie caught the attention of a talent scout from Metro-Goldwyn-Mayer (MGM) when the three Brodel sisters were performing in New York. She was given a six-month contract with the studio, earning $200 per week. While working at the studio, she attended MGM's Little Red Schoolhouse with other child actors like Mickey Rooney and Freddie Bartholomew.  Her first film role was in Camille (1936), a romantic drama starring Greta Garbo and Robert Taylor. She played Taylor's younger sister Marie Jeanette, but her speaking scenes were deleted and she was uncredited. MGM had trouble finding suitable roles for her, and she was let go by the studio along with Deanna Durbin. Leslie returned to New York, working on the radio and as a model. During this time, her older sister Mary was signed to Universal Studios. Leslie returned to Hollywood with the rest of her family, working for different studios as a freelancer. She mainly worked for RKO Pictures.  Leslie was selected to play a small role in Men with Wings (1938). While shooting the film, director William A. Wellman discovered that Leslie's mother had lied about her daughter's age and that she was only thirteen years old. For the remainder of the filming schedule, Wellman replaced her with Mary.  Leslie gained her first credited role in Winter Carnival (1939) as Betsy Phillips. She was chosen for the part because the director was searching for an actress with a southern accent. She was billed as Joan Brodel. Later that year, she co-starred with Jimmy Lydon in Two Thoroughbreds, in which she played the daughter of a horse owner.  At age 15, Leslie was selected by a group of Hollywood directors as one of 13 "baby stars of 1940."
QUESTION: what did she continue making appearances in?
IN: Manorialism was an essential element of feudal society. It was the organizing principle of rural economy that originated in the Roman villa system of the Late Roman Empire, and was widely practiced in medieval western and parts of central Europe. It was slowly replaced by the advent of a money-based market economy and new forms of agrarian contract. Manorialism was characterised by the vesting of legal and economic power in a Lord of the Manor, supported economically from his own direct landholding in a manor (sometimes called a fief), and from the obligatory contributions of a legally subject part of the peasant population under the jurisdiction of himself and his manorial court.

The term is most often used with reference to medieval Western Europe. Antecedents of the system can be traced to the rural economy of the later Roman Empire (Dominate). With a declining birthrate and population, labor was the key factor of production. Successive administrations tried to stabilise the imperial economy by freezing the social structure into place: sons were to succeed their fathers in their trade, councilors were forbidden to resign, and coloni, the cultivators of land, were not to move from the land they were attached to. The workers of the land were on their way to becoming serfs.  Several factors conspired to merge the status of former slaves and former free farmers into a dependent class of such coloni: it was possible to be described as servus et colonus, "both slave and colonus". Laws of Constantine I around 325 both reinforced the semi-servile status of the coloni and limited their rights to sue in the courts; the Codex Theodosianus promulgated under Theodosius II extended these restrictions. The legal status of adscripti, "bound to the soil", contrasted with barbarian foederati, who were permitted to settle within the imperial boundaries, remaining subject to their own traditional law.  As the Germanic kingdoms succeeded Roman authority in the West in the fifth century, Roman landlords were often simply replaced by Germanic ones, with little change to the underlying situation or displacement of populations.  The process of rural self-sufficiency was given an abrupt boost in the eighth century, when normal trade in the Mediterranean Sea was disrupted. The thesis put forward by Henri Pirenne, while disputed widely, supposes that the Arab conquests forced the medieval economy into even greater ruralization and gave rise to the classic feudal pattern of varying degrees of servile peasantry underpinning a hierarchy of localised power centers.
