Question: What is the middle name of the scientist who first sketched out Constructor theory ?
Context: Francis Poulenc completed his Sonate pour violoncelle et piano (Cello Sonata), FP 143, in 1948.  He first sketched it in 1940.  It was dedicated to the French cellist Pierre Fournier, who had helped with the technical aspects of the cello part, as the composer was unfamiliar with the instrument.  The work was published by Heugel in Paris. Constructor theory is a proposal for a new mode of explanation in fundamental physics, first sketched out by David Deutsch, a quantum physicist at the University of Oxford, in 2012.  Constructor theory expresses physical laws exclusively in terms of what physical transformations, or tasks, are possible versus which are impossible, and why.  By allowing such counterfactual statements into fundamental physics, it allows new physical laws to be expressed, for instance those of the constructor theory of information. Boulevard Montmartre: Mardi Gras (Paris, 1897) by Camille Pissarro currently resides in the permanent exhibition at the Armand Hammer Museum in Los Angeles, California.  This work is part of a series of fourteen paintings depicting different times of the day and seasons of the Boulevard Montmartre in Paris.  Camille Pissarro is known as the "Father of Impression" for his "teacher's eye" of drawing what he saw in front of him.  Pissarro first sketched this idea, before using oil on canvas to paint from his balcony window of the Grand Hôtel de Russie overlooking the grand boulevard.  He depicts a nineteenth century Mardi Gras procession, also known as the Carnaval de Paris from the streets below extending its grandeur far into the distance.  The Carnaval de Paris also included a parade before the masked ball at the Paris Opera House.  This street scene focuses on the idea of a "New Paris" that reveals an outdoor natural setting of beauty without adulteration in order to educate the public of real ideas.  This painting marks one of Pissarro's last major works due to his weakening eyesight commonly associated with his elderly age.  Many critics believe that this disability formed his appearance of unclear, spontaneous, artistic freedom. David Elieser Deutsch, FRS (born 18 May 1953), is an Israeli-born British physicist at the University of Oxford.  He is a Visiting Professor in the Department of Atomic and Laser Physics at the Centre for Quantum Computation (CQC) in the Clarendon Laboratory of the University of Oxford.  He pioneered the field of quantum computation by formulating a description for a quantum Turing machine, as well as specifying an algorithm designed to run on a quantum computer.  He is a proponent of the many-worlds interpretation of quantum mechanics. In several cultures, people's names usually include one or more names in addition to the portion that is usually considered adequate to identify them.  In a number of cultures where a given name is expected to precede the surname, such a name is likely to be placed after the given name and before the surname, and thus called a middle name.  In English-speaking American culture, that term is often applied (arguably mistakenly) to names, occupying that position, even if the bearer would insist that that name is being mistakenly called a "middle name", and is actually (to mention several types of atypical cases): Mochong or Mochon is a major prehistoric archaeological site on the island of Rota in the Northern Mariana Islands.  It is an extensive village site on the northern side of the island with 47 latte stone house sites, including an extremely rare structure with 14 columns.  It also has a latte stone wall, consisting of six columns and five slabs, that is more than 50 ft long.  The site has been radiocarbon dated to c. 1000 BCE.  The site was first sketched in the early 19th century by the French explorer Louis de Freycinet, and was in remarkably intact condition (compared to those sketches) in the 1980s. Francesco Lana de Terzi (Brescia, Lombardy 1631 – 22 February 1687 Brescia, Lombardy) was an Italian Jesuit priest, mathematician, naturalist and aeronautics pioneer.  Having been professor of physics and mathematics at Brescia, he first sketched the concept for a vacuum airship and has been referred to as the Father of Aeronautics for his pioneering efforts, turning the aeronautics field into a science by establishing "a theory of aerial navigation verified by mathematical accuracy".  He also developed the idea that developed into Braille. Barend or (somewhat dated spelling) Barent is a Dutch male given name and occasional middle name.  As of 2014, there are over than 4,000 men in the Netherlands with this as their first name, and nearly 3,000 with it as their middle name.  It was likely derived from Bernard.  Notable people with the name include: Russian Gap ( ) is a gap extending in a north-south direction between the Havre Mountains and Rouen Mountains, in the north part of Alexander Island, Antarctica.  The north coast of Alexander Island was first sketched from a great distance in 1821 by the Russian expedition under Fabian Gottlieb von Bellingshausen and this gap apparently represented by one of two open spaces between three high features.  The gap was mapped in detail from air photos taken by the Ronne Antarctic Research Expedition (RARE), 1947–48, by Searle of the Falkland Islands Dependencies Survey (FIDS) in 1960.  Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for the Russian group which observed this area in 1821.  The Russian Gap and Edwards Gap are the only two gaps of Alexander Island. Swedenborg's Flying Machine was first sketched by the Swedish scientist Emanuel Swedenborg in 1714, when he was 26 years old.  It was later published in his periodical, "Daedalus Hyperboreus", in 1716.  While Leonardo da Vinci’s designs predate those of Swedenborg, da Vinci’s manuscripts remained unknown due to a variety of circumstances until the late 19th century.  So, in terms of influence, Swedenborg predated da Vinci.
