Dagmar Renate Kirchner Henney (born May 6, 1931) is a German-born American mathematician and former professor of calculus, finite mathematics, and measure and integration at George Washington University in Washington, DC. == Early life and education == Henney was born in Berlin, Germany as Dagmar Renate Kirchner to Albert, a scientist, and Margot Kirchner. Though her father was Catholic, Henney's mother was Jewish, which made her a target of the Nazi Party.〔 〕 During the war, Henney's mother was taken to Auschwitz where she later died. Not long after, Henney and her father went on the run; splitting their time between the cities of Berlin and Hamburg in an effort to avoid the Nazi Party. In an interview, Henney recalled that at one point during this period, she found twenty bombshells scattered on her front lawn.〔 〕 As a Jewish child, Henney was not allowed to enroll in a formal school during the war years. Her father taught her chess and mathematics at home, rewarding her with a mathematical problem set if she won a game.〔 At age 10, Henney took the admittance exam for admission to the Abitur High School in Hamburg, Germany, from which she would graduate. When recalling one of the questions given to her in the exam, Henney remembered that "there were questions about a frog climbing a flag pole...he'd climb up a few centimeters and then slip back", and that it was her job to "figure how long it would take him to climb the pole."〔Barnes, Bart. "Wife Finds Diploma Fee Is Essential." Washington Post 5 June 1956, section E〕 At the age of 21, Henney moved to the United States in pursuit of a college degree. She had accumulated 63 transferable credits from her high school studies, and was able to matriculate rapidly at the University of Miami in Miami, Florida.〔 She continued to study mathematics, taking classes in nuclear physics and advanced calculus. It was also at this time that she developed a secondary interest in linguistic studies. Henney found a mentor in professor of linguistics Jack Reynolds. She enrolled in classes such as Middle English, Old English, and Chaucer linguistics.〔 In addition to her coursework, Henney took on part-time jobs in Miami. She worked as a movie theater cashier, making 57 cents an hour, and 〔"UM Math Whiz Has Formula." The Miami Herald () 5 Feb. 1956, section 3 - b.〕 taught classes at the University, teaching up to twelve credits a semester. At the age of 24, three years after she enrolled, Henney graduated from the University of Miami with a Bachelor of Science degree with a major in physics and a minor in mathematics and chemistry, as well as a Master of Science degree in pure mathematics.〔 It was during her freshman year at the University of Miami, Henney met her future husband, Alan G. Henney, in a nuclear physics class.〔 After graduating from the University of Miami, Henney and her husband moved to Takoma Park, Maryland, in order to allow her husband to accept a position at the Naval Ordnance Laboratory.〔 She began work on her doctorate at the University of Maryland at College Park, where she taught 18 credits of classes and oversaw the department's of off-campus classes. The latter made her responsible for coordinating the hiring and managing of off-campus professors and teaching assistants, as well as making her a liaison with the University's numerous international students.〔 It was during this time that Henney wrote her dissertation "The theory of set-valued additive functions defined on base-cones in Banach spaces with values in the collection of compact, convex sets".〔 The adviser to her dissertation was German Professor Gottfried Köthe, the founding director of the Institute for Applied Mathematics at the University of Heidelberg.〔 She successfully defended her dissertation in 1965. Instead of receiving her diploma during the award ceremony, she was handed a blank piece of paper, as she had forgotten to pay the University's graduation fee.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dagmar R.
