IN: Hedy Lamarr (; born Hedwig Eva Maria Kiesler, November 9, 1914 -  January 19, 2000) was an Austrian-born American film actress and inventor. At the beginning of World War II, Lamarr and composer George Antheil developed a radio guidance system for Allied torpedoes, which used spread spectrum and frequency hopping technology to defeat the threat of jamming by the Axis powers. Although the US Navy did not adopt the technology until the 1960s, the principles of their work are arguably incorporated into Bluetooth technology, and are similar to methods used in legacy versions of CDMA and Wi-Fi.

Lamarr was born Hedwig Eva Maria Kiesler in 1914 in Vienna, Austria-Hungary, the only child of Gertrud "Trude" Kiesler (nee Lichtwitz; 1894-1977) and Emil Kiesler (1880-1935). Her father was born to a Jewish family in Lemberg (now Lviv in Ukraine) and was a successful bank director.  Her mother Gertrud was a pianist and Budapest native who came from an upper-class Jewish family; she had converted from Judaism to Catholicism and was described as a "practicing Christian", who raised her daughter as a Christian. Lamarr helped get her mother out of Austria (then under Nazi domination) and to the United States, and she later became an American citizen. Gertrud Kiesler put "Hebrew" as her race on her petition for naturalization as an American citizen.  In the late 1920s, Lamarr was discovered as an actress and brought to Berlin by producer Max Reinhardt. Following her training in the theater, she returned to Vienna to work in the film industry, first as a script girl, and soon as an actress. In early 1933, at age 18, she starred in Gustav Machaty's film, Ecstasy (Ekstase in German, Extase in Czech). Her role was that of a neglected young wife married to an indifferent older man. The film became both celebrated and notorious for showing Lamarr's face in the throes of orgasm as well as close-up and brief nude scenes, a result of her being "duped" by the director and producer, who used high-power telephoto lenses.  Although she was dismayed and now disillusioned about taking other roles, the film gained world recognition after winning an award in Rome. Throughout Europe, the film was considered an artistic work, while in America, it was considered overly sexual and received negative publicity, especially among women's groups. It was banned there and in Germany.  She went on to play a number of stage roles, including a starring one in Sissy, a play about Austrian royalty produced in Vienna, which won accolades from critics. Admirers sent roses to her dressing room and tried to get backstage to meet her. She sent most of them away, including a man who was more insistent, Friedrich Mandl. He became obsessed with getting to know her. She fell for his charming and fascinating personality, partly due to his immense financial status. Her parents, both of Jewish descent, did not approve, due to Mandl's ties to Mussolini, and later, Hitler, but could not stop the headstrong Hedy.
QUESTION: How did she start her career?
IN: Harriet Tubman (born Araminta Ross, c. 1822 - March 10, 1913) was an American abolitionist. Born into slavery, Tubman escaped and subsequently made some thirteen missions to rescue approximately seventy enslaved people, family and friends, using the network of antislavery activists and safe houses known as the Underground Railroad. She later helped abolitionist John Brown recruit men for his raid on Harpers Ferry.

Tubman was born Araminta "Minty" Ross to slave parents, Harriet ("Rit") Green and Ben Ross. Rit was owned by Mary Pattison Brodess (and later her son Edward). Ben was held by Anthony Thompson, who became Mary's second husband, and who ran a large plantation near Blackwater River in Madison, Maryland. As with many slaves in the United States, neither the exact year nor place of Araminta's birth is known, and historians differ as to the best estimate. Kate Larson records the year as 1822, based on a midwife payment and several other historical documents, including her runaway advertisement, while Jean Humez says "the best current evidence suggests that Tubman was born in 1820, but it might have been a year or two later." Catherine Clinton notes that Tubman reported the year of her birth as 1825, while her death certificate lists 1815 and her gravestone lists 1820. In her Civil War widow's pension records, Tubman claimed she was born in 1820, 1822, and 1825, an indication, perhaps, that she had only a general idea of when she was born.  Modesty, Tubman's maternal grandmother, arrived in the United States on a slave ship from Africa; no information is available about her other ancestors. As a child, Tubman was told that she seemed like an Ashanti person due to her character traits, though no evidence exists to confirm this lineage. Her mother Rit (who may have had a white father) was a cook for the Brodess family. Her father Ben was a skilled woodsman who managed the timber work on Thompson's plantation. They married around 1808 and, according to court records, they had nine children together: Linah, Mariah Ritty, Soph, Robert, Minty (Harriet), Ben, Rachel, Henry, and Moses.  Rit struggled to keep her family together as slavery threatened to tear it apart. Edward Brodess sold three of her daughters (Linah, Mariah Ritty, and Soph), separating them from the family forever. When a trader from Georgia approached Brodess about buying Rit's youngest son, Moses, she hid him for a month, aided by other slaves and free blacks in the community. At one point she confronted her owner about the sale. Finally, Brodess and "the Georgia man" came toward the slave quarters to seize the child, where Rit told them, "You are after my son; but the first man that comes into my house, I will split his head open." Brodess backed away and abandoned the sale. Tubman's biographers agree that stories told about this event within the family influenced her belief in the possibilities of resistance.
