Frederik Hendrik Kreuger (14 May 1928 – 10 January 2015), was a Dutch high voltage scientist and inventor, lived in Delft, the Netherlands, and was professor emeritus of the Delft University of Technology. He was also a professional author of technical literature, nonfiction books, thrillers and a decisive biography of the master forger Han van Meegeren.
The term high voltage usually means electrical energy at voltages high enough to inflict harm on living organisms. Equipment and conductors that carry high voltage warrant particular safety requirements and procedures. In certain industries, high voltage means voltage above a particular threshold (see below). High voltage is used in electrical power distribution, in cathode ray tubes, to generate X-rays and particle beams, to demonstrate arcing, for ignition, in photomultiplier tubes, and in high power amplifier vacuum tubes and other industrial, military and scientific applications.
Delft is a city and municipality in the province of South Holland, Netherlands. It is located between Rotterdam, to the southeast, and The Hague, to the northwest. Together with them, it is part of both Rotterdam–The Hague metropolitan area and the Randstad.
Delft University of Technology also known as TU Delft, is the largest and oldest Dutch public technological university, located in Delft, Netherlands. It counts as one of the best universities for engineering and technology worldwide, typically seen within the top 20. It is repeatedly considered the best university of technology in the Netherlands.
Frederik H. Kreuger stems from an old Amsterdam family where his maternal grandfather ran a small tobacco factory "Het Wapen van Spanje" in the Weteringstraat, in the old town near the Rijksmuseum. He published a Bookabout his grandfather, this tobacco factory and the explosive development of science and technique in the Belle Époque, the period his grandfather lived.
The Belle Époque or La Belle Époque was a period of Western history. It is conventionally dated from the end of the Franco-Prussian War in 1871 to the outbreak of World War I in 1914. Occurring during the era of the French Third Republic, it was a period characterized by optimism, regional peace, economic prosperity, an apex of colonial empires, and technological, scientific, and cultural innovations. In the climate of the period, especially in Paris, the arts flourished. Many masterpieces of literature, music, theater, and visual art gained recognition. The Belle Époque was named in retrospect when it began to be considered a "Golden Age" in contrast to the horrors of World War I. The Belle Epoque was a period in which, according to historian R.R. Palmer, "European civilization achieved its greatest power in global politics, and also exerted its maximum influence upon peoples outside Europe."
He was educated in Haarlem HBS B (a bèta-oriented secondary school), took his Engineer's degree at the Delft University of Technology in the Netherlands and received there his Ph.D. degree in 1961. He worked as a high voltage scientist in Sweden, England and the Netherlands. In the Netherlands he was employed by the electrical industry and became later managing director of the Nederlandse Kabelfabriek in Delft. In 1986 he became a high voltage professor of his Alma mater in Delft and worked there until 1995.
Haarlem is a city and municipality in the Netherlands. It is the capital of the province of North Holland and is situated at the northern edge of the Randstad, one of the most populated metropolitan areas in Europe. Haarlem had a population of 159,556 in 2017. It is a 15-minute train ride from Amsterdam, and many residents commute to the country's capital for work.
An engineer's degree is an advanced academic degree in engineering that is conferred in Europe, some countries of Latin America, North Africa and a few institutions in the United States. In the United States, the engineer's degree is at a more advanced level than a standard US master's degree. It may include a graduate thesis and dissertation at the level of the doctorates such as the Ph.D.
A Doctor of Philosophy is the highest university degree that is conferred after a course of study by universities in most English-speaking countries. PhDs are awarded for programs across the whole breadth of academic fields. As an earned research degree, those studying for a PhD are usually required to produce original research that expands the boundaries of knowledge, normally in the form of a thesis or dissertation, and defend their work against experts in the field. The completion of a PhD is often a requirement for employment as a university professor, researcher, or scientist in many fields. Individuals who have earned a Doctor of Philosophy degree may, in many jurisdictions, use the title Doctor or, in non-English-speaking countries, variants such as "Dr. phil." with their name, although the proper etiquette associated with this usage may also be subject to the professional ethics of their own scholarly field, culture, or society. Those who teach at universities or work in academic, educational, or research fields are usually addressed by this title "professionally and socially in a salutation or conversation." Alternatively, holders may use post-nominal letters such as "Ph.D.", "PhD", or "DPhil". It is, however, considered incorrect to use both the title and post-nominals at the same time.
He was the inventor of several constructions for high voltage cable systems and of equipment for the detection of partial discharges. Some examples are:
An inventor is a person who creates or discovers a new method, form, device or other useful means that becomes known as an invention. The word inventor comes from the Latin verb invenire, invent-, to find. The system of patents was established to encourage inventors by granting limited-term, limited monopoly on inventions determined to be sufficiently novel, non-obvious, and useful. Although inventing is closely associated with science and engineering, inventors are not necessarily engineers nor scientists.
In electrical engineering, partial discharge (PD) is a localized dielectric breakdown (DB) of a small portion of a solid or fluid electrical insulation (EI) system under high voltage (HV) stress, which does not bridge the space between two conductors. While a corona discharge (CD) is usually revealed by a relatively steady glow or brush discharge (BD) in air, partial discharges within solid insulation system are not visible.
An elastomer is a polymer with viscoelasticity and very weak intermolecular forces, and generally low Young's modulus and high failure strain compared with other materials. The term, a portmanteau of elastic polymer, is often used interchangeably with rubber, although the latter is preferred when referring to vulcanisates. Each of the monomers which link to form the polymer is usually a compound of several elements among carbon, hydrogen, oxygen and silicon. Elastomers are amorphous polymers maintained above their glass transition temperature, so that considerable molecular reconformation, without breaking of covalent bonds, is feasible. At ambient temperatures, such rubbers are thus relatively soft and deformable. Their primary uses are for seals, adhesives and molded flexible parts. Application areas for different types of rubber are manifold and cover segments as diverse as tires, soles for shoes, and damping and insulating elements. The importance of these rubbers can be judged from the fact that global revenues are forecast to rise to US$56 billion in 2020.
His book Partial Discharge Detectionwas for twenty-five years the leading text book in this field. He has also published books about Management and Mismanagement in Research and Disadvantages of Wind Energy. His high voltage laboratory in Delft became a centre of knowledge for partial discharge detection and for the study of Direct current high voltage.
Direct current (DC) is the unidirectional flow of electric charge. A battery is a good example of a DC power supply. Direct current may flow in a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current.
Kreuger was also the inventor of a system for gaining solar power from sea by large floating algea fields producing biofuel (European Patent EP07110895 – 22 June 2007). This project is managed by the Botanical Garden of the Department Biotechnology of the Delft University of Technology; several departments of the University are cooperating herein.
Kreuger made a study of his fellow-townsman Johannes Vermeer and Vermeer's use of the Camera Obscura. He also published a study about the location where Vermeer might have painted his Little Street (Vermeer). An English translation of this study is present in the Municipal archives of Delft.
Kreuger started in 2001 to study the life of the famous Dutch forger Han van Meegeren. His first book on Van Meegeren was a Dutch novel.
It was translated later on in English as "The Deception",also featuring some sketches about the life of Johannes Vermeer. A short biography "Real life of Van Meegeren" is found at the end of this novel.
Kreuger was in an opportune position to write his biography about Van Meegeren because his native language is Dutch and also because he lived in the Netherlands at the time when Van Meegeren was active. He searched for primary sources – especially in the Netherlands – and added in this way to the knowledge gained by John Godley, 3rd Baron Kilbracken,who was a pioneer in this field, and to that of Marie Louise Doudart de la Grée, who interviewed Van Meegeren in 1946 and wrote a Dutch biography in 1966.
Kreuger was fortunate to meet the last living relatives of Han van Meegeren and also the last surviving witness of his arrest, and he discovered an unpublished biography of Van Meegeren's son Jacques, containing new information on the artist's life. Besides he found unknown photographs related to Van Meegeren.
In addition, he revealed paintings under the artist's own name and he also identified some more fake Old Masters made by Van Meegeren.
In 2004, he published his findings in Dutch in Han van Meegeren, Meestervervalser,where new facts and newly found works of Van Meegeren were collected.
In 2006 followed De Arrestatie van een Meestervervalser,again in Dutch, in which the many reactions on his first biography were incorporated.
The resulting English biography A New Vermeer. Life and Work of Han van Meegeren
In this book he also describes the life of Van Meegeren's son Jacques van Meegeren; he discovered that Jacques in his turn had forged the work of his father.
Kreuger played the leading violin in the amateur gipsy orchestra Siperkov Ensemble. He made a study of Gipsy or Romani music and published a book in Dutchabout the history and perception of Gipsy music. An excerpt of this book appeared as the article "Zigeunermuziek" in the Dutch version of Wikipedia.
The scientific career of Frederik Hendrik Kreuger by Morshuis, P.H.F.reviews the career of Frederik Hendrik Kreuger and his work in the field of high voltage research:
On 10 January 2015, NRC Handelsblad announced Kreuger died in Delft, aged 86.
Numerous publications for CIGRE, in the Transactions of the IEEE Institute of Electrical and Electronics Engineers and many other scientific periodicals.
Johannes Vermeer was a Dutch Baroque Period painter who specialized in domestic interior scenes of middle-class life. He was a moderately successful provincial genre painter in his lifetime but evidently was not wealthy, leaving his wife and children in debt at his death, perhaps because he produced relatively few paintings.
Henricus Antonius "Han" van Meegeren was a Dutch painter and portraitist and is considered to be one of the most ingenious art forgers of the 20th century. Despite his life of crime, van Meegeren became a national hero after World War II when it was revealed that he had sold a forged painting to Reichsmarschall Hermann Göring during the Nazi occupation of the Netherlands.
Carel Pietersz. Fabritius was a Dutch painter. He was a pupil of Rembrandt and worked in his studio in Amsterdam. Fabritius, who was a member of the Delft School, developed his own artistic style and experimented with perspective and lighting. Among his works are A View of Delft (1652), The Goldfinch (1654), and The Sentry (1654).
Art forgery is the creating and selling of works of art which are falsely credited to other, usually more famous artists. Art forgery can be extremely lucrative, but modern dating and analysis techniques have made the identification of forged artwork much simpler.
The Little Street is a painting by the Dutch painter Johannes Vermeer, executed c. 1657–58. It is exhibited at the Rijksmuseum of Amsterdam, and signed, below the window in the lower left-hand corner, "I V MEER".
A Question of Attribution is a 1988 one-act stage play, written by Alan Bennett. It was premièred at the National Theatre, London, in December 1988, along with the stage version of An Englishman Abroad. The two plays are collectively called Single Spies.
Vermeer is a Dutch toponymic surname. It is a contraction of Van der Meer, meaning "from the lake."
Gustaaf Adolf Frederik Molengraaff was a Dutch geologist, biologist and explorer. He became an authority on the geology of South Africa and the Dutch East Indies.
Leonaert Bramer, also Leendert or Leonard, was a Dutch painter known primarily for genre, religious, and history paintings. Very prolific as a painter and draftsman, he is noted especially for nocturnal scenes which show a penchant for exotic details of costume and setting. He also painted frescos—a rarity north of the Alps—which have not survived, as well as murals on canvas, few of which are extant. Bramer is one of the most intriguing personalities in seventeenth-century Dutch art.
Jonathan Lopez is an American writer and art historian. Born in 1969 in New York City, he was educated there and at Harvard. He writes a monthly column for Art & Antiques called "Talking Pictures" and is a frequent contributor to London-based Apollo: The International Magazine of the Arts. His noted December 2007 Apollo article "Gross False Pretences" related the details of an acrimonious 1908 dispute between the art dealer Leo Nardus and the wealthy industrialist Peter Arrell Brown Widener of Philadelphia. Lopez has also written for ARTnews, the Associated Press, U.S. News & World Report, The Boston Globe, The International Herald Tribune, and the Dutch newsweekly De Groene Amsterdammer. His book, The Man Who Made Vermeers is a biography of the Dutch art forger Han van Meegeren.
Jacques Henri Emil van Meegeren was a Dutch illustrator and painter.
A high-voltage cable is a cable used for electric power transmission at high voltage. A cable includes a conductor and insulation, and is suitable for being run underground or underwater. This is in contrast to an overhead line, which does not have insulation. High-voltage cables of differing types have a variety of applications in instruments, ignition systems, and alternating current (AC) and direct current (DC) power transmission. In all applications, the insulation of the cable must not deteriorate due to the high-voltage stress, ozone produced by electric discharges in air, or tracking. The cable system must prevent contact of the high-voltage conductor with other objects or persons, and must contain and control leakage current. Cable joints and terminals must be designed to control the high-voltage stress to prevent breakdown of the insulation. Often a high-voltage cable will have a metallic shield layer over the insulation, connected to the ground and designed to equalize the dielectric stress on the insulation layer.
Hans Jordaens the Elder, was a Flemish Baroque painter whose religious works are often confused with that of other painters with the same name.
The Procuress is the name given to a number of similar paintings by the Dutch Golden Age painter Dirck van Baburen. The painting is in the Caravaggiesque style of the Utrecht school.
Karel van Mander the Younger (1579–1623) was a Dutch Golden Age painter and the son of Karel van Mander.
The Procuress is a 1656 oil-on-canvas painting by the 24-year-old Johannes Vermeer. It can be seen in the Gemäldegalerie Alte Meister in Dresden. It is his first genre painting and shows a scene of contemporary life, an image of mercenary love perhaps in a brothel. It differs from his earlier biblical and mythological scenes. It is one of only three paintings Vermeer signed and dated.
Theo van Wijngaarden was a Dutch art forger.
