Nils_Vogt_(comedian)

Nils Henning Vogt (born (1948-04-29)April 29, 1948) is a Norwegian actor who is best known for some of his comedy roles, particularly as the temperamental small business owner Karl Reverud in the sit-coms Mot i brøstet (which he also directed) from 1993 to 1997, Karl & Co from 1998 to 2001 and Karl III in 2009.

Edgar_Ende

Edgar Karl Alfons Ende (23 February 1901 – 27 December 1965) was a German surrealist painter and father of the children's novelist Michael Ende.
Ende attended the Altona School of Arts and Crafts from 1916 to 1920. In 1922 he married Gertrude Strunck, but divorced four years later. He remarried in 1929, the same year his son Michael was born. In the 1930s Ende's Surrealist paintings began to attract considerable critical attention, but were then condemned as degenerate by the Nazi government. Beginning in 1936 the Nazis forbade him to continue to paint or exhibit his work. In 1940 he was conscripted into the Luftwaffe as an operator of anti-aircraft artillery.
The majority of his paintings were destroyed by a bomb raid on Munich in 1944, making his surviving pre-war work extremely rare. In 1951, Ende met the recognized founder of Surrealism, André Breton, who admired his work and declared him an official Surrealist. He continued to paint surrealist works until his death in 1965 from a myocardial infarction.
Ende's paintings are thought to have had a significant influence on his son's writing. This is inferred in the scenes depicting the surreal dream-paintings from Yor's Minroud in Die Unendliche Geschichte (The Neverending Story), and is made explicit in Michael Ende's book Der Spiegel im Spiegel (The mirror in the mirror), a collection of short stories based on (and printed alongside) Edgar Ende's surrealist works.

Karl_Slotta

Karl Heinrich Slotta (May 12, 1895 in Breslau, Germany (now Wrocław, Poland) – July 17, 1987 in Coral Gables, Florida), was a biochemist. His discovery of progesterone and its relationship to ovulation led to the development of birth control pills.

Stuart_Dreyfus

A native of Terre Haute, Indiana, Stuart E. Dreyfus is professor emeritus at University of California, Berkeley in the Industrial Engineering and Operations Research Department. While at the Rand Corporation he was a programmer of the JOHNNIAC computer. While at Rand he coauthored Applied Dynamic Programming with Richard Bellman. Following that work, he was encouraged to pursue a Ph.D. which he completed in applied mathematics at Harvard University in 1964, on the calculus of variations. In 1962, Dreyfus simplified the Dynamic Programming-based derivation of backpropagation (due to Henry J. Kelley and Arthur E. Bryson) using only the chain rule. He also coauthored Mind Over Machine with his brother Hubert Dreyfus in 1986.

Alfredo_Duhalde

Alfredo Duhalde Vásquez (June 30, 1898 – April 10, 1985) was a Chilean politician who served twice as provisional president in 1946.
Duhalde was born in the city of Río Bueno, the son of Pedro Duhalde and of Zoila Vasquez. After completing his primary schooling in his natal town, he completed his secondary education at the Liceo de Aplicación in Santiago, where he graduated in 1916. He then studied law at the Universidad de Chile. He married Yolanda Heufmann, and together they had 6 children: Yolanda, René, Sara, Carmen, Marta and Sonia.
He joined the army and was commissioned as a Cavalry Lieutenant. Later he dedicated himself to work his lands in the areas of Río Bueno and La Unión. He was one of the founders of the Banco Agrícola (Agricultural Bank). He joined the Radical Party and was elected a deputy in 1924 for Llanquihue and Carelmapu. In 1933 he was re-elected, this time as a deputy for Valdivia, Osorno y La Unión.
In 1939, President Pedro Aguirre Cerda appointed him Minister of Defense, position he held until 1940, and then again between 1942 and 1944 under President Juan Antonio Rios. In 1945 he was elected a Senator for Valdivia, Osorno, Llanquihue, Aysén, Chiloé and Magallanes. On September 26 of the same year, he was appointed Minister of the Interior, and assumed as vice president during the absence of President Rios, who had travelled to the United States. President Ríos returned and reassumed power on December 3, but by then he was already very ill and had to hand over his powers to Duhalde again a little more than a month later on January 17, 1946.
Duhalde assumed as vice president again until the death of President Rios, on June 27, when he became Acting President. On August 3 of the same year, he stepped down once again in order to run in his party's primaries for the upcoming presidential election, which he lost to Gabriel González Videla, who went on to win the general election later that year. He resumed as vice president on August 13, having been replaced in the interim by Vice Admiral Vicente Merino, and continued in office until October 17, when he finally stepped down completely, being replaced by his minister of the Interior, Juan Antonio Iribarren.
He remained a Senator until 1953, when he retired permanently from politics. Duhalde also was director and president of the Banco Osorno- La Unión (1960–1966), Presidente of the Athletic Federation of Chile, partner of the Duhalde, Dibarrant and Co. and honorary director of Colo-Colo F.C. He died in the city of Santiago in 1985.

François-Louis_Ganshof

François Louis Ganshof (14 March 1895, Bruges – 26 July 1980, Brussels) was a Belgian medievalist. After studies at the Athénée Royal, he attended the University of Ghent, where he came under the influence of Henri Pirenne. After studies with Ferdinand Lot, he practiced law for a period, before returning to the University of Ghent. Here he succeeded Pirenne in 1930 as professor of medieval history, after Pirenne left the university as a result of the enforcement of Dutch as language of instruction. He remained there until his retirement in 1961.
Ganshof's work was primarily on Flanders in the Carolingian period. His best known book is Qu'est-ce que la féodalité? (1944). Here he defines feudalism narrowly, in simple legal and military terms. Feudalism, in Ganshof's view, existed only within the nobility. This contrasts with Marc Bloch, where feudalism encompasses society as a whole, and Susan Reynolds, who questions the concept of feudalism in itself.
Though Ganshof's definition is not always accepted today, this book was not his only work. He contributed greatly to his field, mostly through articles. Among the few books he published were Les Destinées de l'Empire en occident de 395 à 888 (1928) and Flandre sous les premiers comtes (1943). In 1946 he received the Francqui Prize for Human Sciences.
Ganshof was renowned as the greatest European expert on the Frankish kingdoms, particularly under the Carolingian dynasty; he never wrote the definitive biography of Charlemagne that everyone expected of him, but his contributions to Frankish history continue to be fundamental. The best English-language introduction to this (very major) aspect of his work is in F.L. Ganshof, The Carolingians and the Frankish Monarchy. Studies in Carolingian History, tr. Janet Sondheimer (London: Longman, 1971). This collection of major articles ends with an exhaustive bibliography of Ganshof's writings on Merovingian and Carolingian history down to 1970.

Henriette_Davidis

Johanna Friederika Henriette Katharina Davidis (1 March 1801 in Wengern – 3 April 1876 in Dortmund) arguably is Germany's most famous cookbook author. Although many similar cookbooks had been published by then, amongst others Sophie Wilhelmine Scheibler's Allgemeines deutsches Kochbuch für bürgerliche Haushaltungen in several editions, Davidis' Praktisches Kochbuch (Practical Cookbook) became the reference cookbook of the late 19th and early 20th century, a standard in German households. The large number of second-hand copies still available, frequently heavily annotated, are proof that the books were in much use. In many families Praktisches Kochbuch was handed down through the generations.
However the cookbook was only one facet of the extensive educational program Davidis devised for young women. Starting with the Puppenköchin (Dolls' Cook) for very young girls on to young unmarried women, and finally housewives responsible for their own household and servants, Davidis' books offered advice and information. This was rooted in the conviction that being a housewife was a demanding activity in its own right for which young women of the middle class emerging at the time were frequently ill-prepared.
While authoring her books Davidis first worked as a home economist, teacher, and governess, but later on concentrated exclusively on writing. Although her books, in particular Praktisches Kochbuch which had reached its 21st edition when she died, were hugely successful even during her lifetime, she had to live very modestly and only at the age of 74 years was able to afford her own flat. Occasionally sources claim "Henriette Davidis" to be the pseudonym used by a certain Helena Clemen. However Helena Clemen was one of Davidis' readers who had sent in suggestions which the author used in her writings.Today the Henriette-Davidis-Museum in Wetter-Wengern keeps her memory alive with cookbook exhibitions and a monograph series. Parts of a stone-built stove from the Wengern vicary together with a memorial plaque were bricked in the local railway bridge abutments, completed in 1934 and for which the vicary had to be demolished.
Due to her huge influence on German food culture and household management she is generally considered to be the German equivalent to Mrs Beeton. The first edition of her classic cookbook Praktisches Kochbuch für die gewöhnliche und feinere Küche was published in 1844 and there were at least seventy-six editions published by 1963.

Simona_Atzori

Simona Atzori (born June 18, 1974) is an Italian artist and dancer who was born in Milan. She was born without arms, and uses her feet to draw, write and perform all other daily activities.Attempts were made to fit Simona with prosthetic arms at an early age, but she very quickly rejected them. She has said that she found the prosthetics extremely heavy and impractical, and it was much easier to use her feet to perform tasks.
She started painting at the age of 4 and her talent was soon noticed by artist Mario Barzon, who encouraged and supported her. In 1983, she was awarded a scholarship from the Association of Mouth and Foot Painting Artists of the World. A defining moment in her early career was an audience with Pope John Paul II, at which she presented him with a portrait of himself.Simona also started to dance at the age of 6. Despite some initial opposition from teachers who felt that it was not appropriate, her own determination and the strong support of her mother enabled her to succeed in a discipline typically associated with the non-disabled.
In 1996, she commenced her studies at the University of Western Ontario in Canada. Her course in Visual Arts enabled her to combine the two passions of her life, and she graduated with honors in 2001.
Later Simona became associated with the Pescara Dance Festival, and has endowed this event with the Atzori Award, given to dancers and choreographers. She continues to perform and exhibit her work all over the world.
On March 10, 2006, Simona performed a dance routine during the Opening Ceremony of the Paralympic Games in Turin.
