Anton Herman Gerard "Anthony" Fokker (6 April 1890 – 23 December 1939) was a Dutch aviation pioneer and aircraft manufacturer. He is most famous for the fighter aircraft he produced in Germany during the First World War such as the Eindecker monoplanes, the Dr.1 triplane and the D.VII biplane.

Aviation Design, development, production, operation and use of aircraft

Aviation, or air transport, refers to the activities surrounding mechanical flight and the aircraft industry. Aircraft includes fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air craft such as balloons and airships.

Fokker Eindecker fighters monoplane fighter aircraft family

The Fokker Eindecker fighters were a series of German World War I monoplane single-seat fighter aircraft designed by Dutch engineer Anthony Fokker. Developed in April 1915, the first Eindecker ("Monoplane") was the first purpose-built German fighter aircraft and the first aircraft to be fitted with a synchronization gear, enabling the pilot to fire a machine gun through the arc of the propeller without striking the blades. The Eindecker gave the German Air Service a degree of air superiority from July 1915 until early 1916. This period, during which Allied aviators regarded their poorly armed aircraft as "Fokker Fodder", became known as the "Fokker Scourge".

Fokker D.VII fighter aircraft

The Fokker D.VII was a German World War I fighter aircraft designed by Reinhold Platz of the Fokker-Flugzeugwerke. Germany produced around 3,300 D.VII aircraft in the second half of 1918. In service with the Luftstreitkräfte, the D.VII quickly proved itself to be a formidable aircraft. The Armistice ending the war specifically required Germany to surrender all D.VIIs to the Allies. Surviving aircraft saw much service with many countries in the years after World War I.

After the Treaty of Versailles forbade Germany to produce airplanes, Fokker moved his business to the Netherlands. There his company was responsible for a variety of successful aircraft including the Fokker trimotor, a successful passenger aircraft of the inter-war years. He died in New York in 1939. Later authors suggest he was personally charismatic but unscrupulous in business and a controversial character.

Treaty of Versailles one of the treaties that ended the First World War

The Treaty of Versailles was the most important of the peace treaties that brought World War I to an end. The Treaty ended the state of war between Germany and the Allied Powers. It was signed on 28 June 1919 in Versailles, exactly five years after the assassination of Archduke Franz Ferdinand, which had directly led to World War I. The other Central Powers on the German side of World War I signed separate treaties. Although the armistice, signed on 11 November 1918, ended the actual fighting, it took six months of Allied negotiations at the Paris Peace Conference to conclude the peace treaty. The treaty was registered by the Secretariat of the League of Nations on 21 October 1919.

Netherlands constituent country of the Kingdom of the Netherlands in Europe

The Netherlands is a country located mainly in Northwestern Europe. The European portion of the Netherlands consists of twelve separate provinces that border Germany to the east, Belgium to the south, and the North Sea to the northwest, with maritime borders in the North Sea with Belgium, Germany and the United Kingdom. Together with three island territories in the Caribbean Sea—Bonaire, Sint Eustatius and Saba— it forms a constituent country of the Kingdom of the Netherlands. The official language is Dutch, but a secondary official language in the province of Friesland is West Frisian.

New York City Largest city in the United States

The City of New York, usually called either New York City (NYC) or simply New York (NY), is the most populous city in the United States and thus also in the state of New York. With an estimated 2017 population of 8,622,698 distributed over a land area of about 302.6 square miles (784 km2), New York is also the most densely populated major city in the United States. Located at the southern tip of the state of New York, the city is the center of the New York metropolitan area, the largest metropolitan area in the world by urban landmass and one of the world's most populous megacities, with an estimated 20,320,876 people in its 2017 Metropolitan Statistical Area and 23,876,155 residents in its Combined Statistical Area. A global power city, New York City has been described as the cultural, financial, and media capital of the world, and exerts a significant impact upon commerce, entertainment, research, technology, education, politics, tourism, art, fashion, and sports. The city's fast pace has inspired the term New York minute. Home to the headquarters of the United Nations, New York is an important center for international diplomacy.

Early life

Anthony (Tony) Fokker was born in Blitar [1] (then Dutch East Indies, now Indonesia), to Herman Fokker, a Dutch coffee plantation owner. Some sources say that he was born in Kediri. At that time, Blitar was a part of the 'Kediri Residency', a colonial administrative division the capital of which was in Kediri. When Fokker was four, the family returned to the Netherlands and settled in Haarlem in order to provide Fokker and his older sister, Toos, with a Dutch upbringing.[ citation needed ]

Blitar City in East Java, Indonesia

Blitar is a city in East Java, Indonesia, about 73 km from Malang and 167 km from Surabaya. The area lies within longitude 111° 40' - 112° 09' East and its latitude is 8° 06' South. The city of Blitar lies at an altitude on average 167 metres above sea level.

Dutch East Indies Dutch possession in Southeast Asia between 1810-1945

The Dutch East Indies was a Dutch colony consisting of what is now Indonesia. It was formed from the nationalised colonies of the Dutch East India Company, which came under the administration of the Dutch government in 1800.

Indonesia Republic in Southeast Asia

Indonesia, officially the Republic of Indonesia, is a country in Southeast Asia, between the Indian and Pacific oceans. It is the world's largest island country, with more than seventeen thousand islands, and at 1,904,569 square kilometres, the 14th largest by land area and the 7th largest in combined sea and land area. With over 261 million people, it is the world's 4th most populous country as well as the most populous Muslim-majority country. Java, the world's most populous island, contains more than half of the country's population.

Fokker was not a studious boy and did not complete his high school education. However, he showed an early interest in mechanics, and preferred making things, playing with model trains and steam engines, and experimenting with model aeroplane designs.[ citation needed ]

He devoted considerable effort[ when? ] to the development of a wheel that would not suffer from punctures, basically a wheel with a perimeter formed by a series of metal plates. This idea had been experimented with elsewhere and was already patented.[ citation needed ]

Move to Germany

Fokker's first interest in flight stemmed from Wilbur Wright's exhibition flights in France in the summer and fall of 1908. In 1910, aged 20, Fokker was sent by his father to Germany to receive training as an automobile mechanic at Bingen Technical school, but his interest was in flying, so he transferred to the Erste deutsche Automobil-Fachschule in Mainz. [2] [ citation needed ] That same year Fokker built his first aircraft " de Spin " ("the Spider"), which was destroyed by his business partner who flew it into a tree. [3] He gained his flying certificate in his second "Spin" aircraft, which shortly thereafter was also destroyed by the same business partner, prompting Fokker to end their cooperation. [4] In his own country, he became a celebrity by flying around the tower of the Grote or St.-Bavokerk in Haarlem on 1 September 1911, [5] with the third version of the "Spin". [6] One day earlier, on Queen's Day (31 August, Queen Wilhelmina's birthday), Fokker had already taken the opportunity to make a couple of demonstration flights in Haarlem in the same aircraft.

Germany Federal parliamentary republic in central-western Europe

Germany, officially the Federal Republic of Germany, is a country in Central and Western Europe, lying between the Baltic and North Seas to the north, and the Alps to the south. It borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, France to the southwest, and Luxembourg, Belgium and the Netherlands to the west.

Mechanic profession

A mechanic is a tradesman, craftsman or technician who uses tools to build or repair machinery.

Fokker Spin airplane

The Fokker Spin was the first airplane built by Dutch aviation pioneer Anthony Fokker. The many bracing wires used to strengthen the aircraft made it resemble a giant spider, hence its name Spin, and Spinne in German.

In 1912, Fokker moved to Johannisthal near Berlin where he founded his first own company, Fokker Aeroplanbau. In the following years he constructed a variety of airplanes. He relocated his factory to Schwerin where it was renamed Fokker Flugzeugwerke GmbH, and later shortened to Fokker Werke GmbH.[ citation needed ]

Involvement in World War I

At the outbreak of World War I the German government took control of the factory. Fokker remained as director and alleged designer of many aircraft for the Imperial German Army Air Service ( Luftstreitkräfte ), including the Fokker Eindecker and the Fokker Dr.I, the triplane made famous in the hands of aces such as Manfred von Richthofen (the Red Baron). In all, his company delivered about 700 military planes to the German air force as well as supplying the German navy and Austria-Hungary.

Fokker himself was a skilled pilot, demonstrating his aircraft on many occasions. [7] On 13 June 1915, Fokker demonstrated the new Eindecker (monoplane) at Stenay in the German 5th Army Sector in front of the German Crown Prince and other VIPs. Fokker worked closely with an accomplished military pilot, Otto Parschau, to bring the Eindecker into military use and on this occasion both men demonstrated the aircraft. Max Immelmann, later to become a high-scoring Flying Ace with the Eindecker, commented in a letter written shortly after this event on 25 June 1915 that: [7] "Fokker, especially, amazed us with his skill".

Author A.R. Weyl (Fokker: the creative years, Putnam 1965) says that, while Fokker was a talented and bold pilot, his business character was more flawed. He failed to reinvest war profits back into his factory which consequentially struggled to fulfill war contracts as the factory floor was often muddled with prototype development and production taking place at the same time. Fokker distrusted qualified engineers (which he was not) and resented frequent German insistence on carrying out stringent structural tests to ensure prototype aircraft were fit for combat. He could be bad tempered and insensitive as when he verbally abused his dying designer Martin Kreuzer on the evening of 27 June 1916, after Kreuzer had crashed the prototype Fokker D.I. The rudder jammed but Kreuzer was able to give a verbal report on the accident before he died. "Fokker hurried to the scene and shouted reproaches at the mortally injured man". Weyl says this incident was witnessed by Reinhold Platz, who succeeded Kreuzer.

While Weyl's biography paints an unpleasant picture of Fokker as a businessman, he was a popular and charismatic figure with service pilots and could charm even senior officers. This charm enabled him to deal with the first major crisis of his German career when his newly delivered Fokker Dr.I triplanes began to experience sudden fatal accidents in late 1917 and the type was temporarily grounded as too dangerous to fly. The triplanes' top wings frequently ripped off under aerobatic conditions and even Lothar von Richthofen (brother of Manfred) was lucky to survive one such crash. Fokker was able to prove to the German high command that the basic design was not at fault but the German military inquiry concluded that shoddy workmanship due to poor supervision and quality control at the Fokker factory were to blame. Fokker received a stern warning about future conduct. Unfortunately the same scenario repeated itself again, a few months later, with the introduction of his E.V/D.VIII monoplane in mid-1918. A further high level German inquiry revealed more production and workmanship issues. Weyl asserts that the German authorities were now willing to file criminal charges against Fokker and might have done so, had he not returned to the Netherlands shortly after the end of World War I.

Fokker's own account of the D.VIII places the blame on officious German Air Force inspectors requiring an ill-conceived design change. "When the first D-8[sic] was submitted to the engineering division to be sandload tested, the wings proved to be sufficiently strong, but the regulations called for a proportionate strength in the rear spar compared to the front spar... Complying with the government's edict, we strengthened the rear spar and started to produce in quantity... [8] " The D.VIII's immediately ran into trouble with the wing collapsing at high speed. Fokker recalled the aircraft for further testing, and successfully demonstrated that the reinforced rear spar caused the wings to flex unevenly at speed, increasing the angle of attack at the wing tips and causing the wing to shear apart under the increased loads. The problem was resolved by restoring the rear spar to its original specifications. [9]

Weyl also discusses claims of Fokker's outright plagiarism or taking sole credit for the work of his staff, first designer Martin Kreuzer and later Reinhold Platz. For example, contemporary German documents for the E.V/D.VIII refer to Fokker as 'the designer' but Weyl and other authors now suggest that Platz was the real design genius behind the Dr.I, D.VII and D.VIII. There may be some truth in this as Platz recalled to Weyl that he attended high level meetings alongside Fokker but was never introduced or referred-to as the designer and often never even spoke. Yet when Fokker fled Germany it was Platz who immediately took over the German works on Fokker's behalf. Fokker later moved Platz to the Netherlands, as head designer, when the post-war German operation collapsed which indicates Platz really did play a greater design role than Fokker admits. Weyl uncharitably suggests that Platz's role at the Fokker D.VIII crisis meetings was to take the blame if anything was wrong and not receive credit. How much of this interpretation is based on the fact that Platz was still alive to tell his side of the story in 1965, and Fokker was not, is unclear.

Another book by Henri Hegener (who knew both Fokker and Platz personally) depicts a rather different story, saying that Platz, while a skilled craftsman (and excellent welder), had received no formal technical training, and that his contributions to the Fokker designs are exaggerated, although Hegener grants that Platz was a good "rule of thumb" designer. Hegener also contradicts the claims that Platz was treated badly by Fokker, at least not financially because Platz's year-end bonuses often exceeded his yearly salary. [10]

The interrupter gear

Fokker is often credited with having invented the synchronization device [11] which enabled World War I aircraft to fire through the spinning propeller. His role was certainly significant but there were a number of prior developments before the result was achieved for which Fokker is commonly credited.

The famous French pilot Roland Garros was shot down on 18 April 1915. His aircraft had been fitted with a deflector device, whereby metal deflector wedges were fitted to the airscrew. Garros was able to set fire to the airframe before being taken prisoner but the aircraft's gun and the armoured propeller remained intact and came into German hands. [7]

This initiated a phase of consideration of the interrupter gear concept in the Imperial German Army Air Service ( Luftstreitkräfte ). Fokker was heavily involved in this process but the story of his conception, development and installation of a synchronization device in a period of 48 hours (first found in an authorized biography of Fokker written in 1929) has been shown to be not factual. The available evidence points to a synchronisation device having been in development with Fokker's company for perhaps six months prior to the capture of Garros' machine. [7] Additionally there were patents filed in France, Germany and Austria-Hungary as far back as 1910 which show a very similar device to that pioneered by Fokker. Author A. J. Weyl suggests that Fokker – or more probably someone on his production team – were aware of these patents. One patentee, Franz Schneider and his employer LVG, later sued Fokker in the German courts and won their case; but Fokker (by now in America) refused to pay up.

However the final result of the development was Fokker's pushrod control mechanism, Gestängesteuerung, which allowed the aircraft's forward-firing machine gun to fire only when the propeller was out of the line of fire. As incorporated into the famous Fokker Eindecker, its use directly led to a phase of German air superiority known as the Fokker Scourge. [11] Despite its shock effect on the enemy, the first Fokker interrupters remained unreliable and were prone to failures. Both Oswald Boelcke and Max Immelmann survived failures which resulted in propellers being shot off and even engines pulled out of their mountings due to the engine becoming unbalanced by the loss of the propeller. Immelmann's eventual death in combat has also been attributed to interrupter gear failure as the aircraft was seen to break up in mid-air while engaged against a Royal Flying Corps F.E.2b.

Other works on aircraft armament

Fokker and his armament team, including Lübbe and Leimberger, also worked on lesser known projects, including a multi-barrelled machine gun, known as the Fokker-Leimberger. [12] Although superficially similar to a Gatling, the action of the Fokker-Leimberger was substantially different. Problems with the gun, especially with ruptured cases, prevented its adoption into production during the war. [13] After moving to the US, Fokker continued to work on the design, but he was ultimately unsuccessful—properly sealing the rotary split-breech was apparently very difficult. A single surviving prototype is known today at the Kentucky Military Treasures. [14] [15]

Return to the Netherlands

After the war's end, the terms of the Treaty of Versailles forbade Germany to build any aircraft or aircraft engines. The treaty singled out the Fokker D.VII for destruction or confiscation, the only aircraft to be named in the treaty. In 1919 Fokker returned to the Netherlands and started a new aircraft company, the Nederlandse Vliegtuigenfabriek (Dutch Aircraft Factory), predecessor to the Fokker Aircraft Company. Despite the strict disarmament conditions in the Treaty, Fokker did not return home empty-handed: he managed to smuggle six goods trains' worth of D.VII and C.I military planes and spare parts out of Germany across the German-Dutch border. Author Weyl says that Fokker used 350 railway wagons and made sure that each train was too long to fit into the railway sidings where trains were normally checked for contraband. Weyl quotes Fokker himself as saying that he paid 20,000 Dutch guilders in bribes. The trains included 220 aeroplanes, more than 400 aero engines and much other material. This initial stock enabled him to quickly set up shop, but his focus shifted from military to civil aircraft such as the very successful Fokker F.VII trimotor.

Fokker's admitted bribery has contributed to his reputation for sharp business practices. Weyl also points out that – in addition to possible criminal charges for the Fokker D.VIII fatal crashes – Fokker also failed to pay taxes to German authorities and actually owed more than 14 million marks. Fokker's autobiography tells a similar story, but focuses on the rampant corruption, hyper-inflation, economic meltdown, and violent revolutionary forces of the pre-Weimar days. According to Fokker's account, as WWI progressed, the German High Command became increasingly brazen, even forcing Fokker into German citizenship against his will. Fokker describes his escape from Germany as a harrowing tale in which he protected as many workers as possible and escaped with less than a quarter of his net worth. He takes pains to rebuff the claim that he left the country owing any taxes. [16]

Personal life

On 25 March 1919, Fokker married Sophie Marie Elisabeth von Morgen in Haarlem. This marriage ended in divorce in 1923. In 1927, he married Canadian Violet Eastman in New York City. On 8 February 1929, she died in a fall from their hotel suite window. The original police report said her death was a suicide, but this was later changed to 'vertigo victim' at the request of her husband's staff. On the subject of his marriages, Fokker wrote, "I have always understood airplanes much better than women. I had more love affairs in my life, and they ended just like the first one, really, because I thought there was nothing that could be more important than my airplanes... I have now learned, by bitter experience, that one must give a little too; in love one has to use one's brain just as much as in business, and perhaps even more". [17]

Move to the US and death

Fokker's grave in Driehuis

In or about 1926 or 1927, Fokker moved to the United States. Here he established the North American branch of his company, the Atlantic Aircraft Corporation.

He was the maker of the Fokker F-VII airplane Josephine Ford (named after the grand daughter of automobile magnate Henry Ford), which Lieutenant Commander Richard E. Byrd and Machinist Floyd Bennett flew over or near the North Pole on 9 May 1926.

In 1931, Fokker sold his American aircraft plants to General Motors, whereupon they became the company's General Aviation division.

Neville Shute in 1934 negotiated with Fokker for a manufacturing licencing agreement for Airspeed Ltd (England), and found him genial, shrewd and helpful but already a sick man; and he was difficult to deal with as his domestic life was irregular. He worked at all hours and in strange places. Frequently his very efficient legal advisor and secretary could not tell us where he was. Shute said he was a good chooser of men and had a most efficient staff of Dutchmen and ex-Germans. [18]

Fokker died at age 49 in New York in 1939 from pneumococcal meningitis, after a three-week-long illness. [19] In 1940, his ashes were brought to Westerveld Cemetery in Driehuis, North Holland, where they were buried in the family grave.

In 1970, Fokker was inducted into the International Air & Space Hall of Fame. [20]

Fokker's nickname was The Flying Dutchman . [21] In popular media, Hurd Hatfield portrayed him in the 1971 film Von Richthofen and Brown and the character Roy Fokker from the animated series Macross was named in honor of Anthony Fokker. Fokker is portrayed by Craig Kelly in the Young Indiana Jones Chronicles: Attack of the Hawkmen.

Synchronization gear aircraft armament component

A synchronization gear, or a gun synchronizer, sometimes rather less accurately called an interrupter, is attached to the armament of a single-engine tractor-configuration aircraft so it can fire through the arc of its spinning propeller without bullets striking the blades. The idea presupposes a fixed armament directed by aiming the aircraft in which it is fitted at the target, rather than aiming the gun independently.

The Fokker E.V was a German parasol-monoplane fighter aircraft designed by Reinhold Platz and built by Fokker-Flugzeugwerke. The E.V was the last Fokker design to become operational with the Luftstreitkräfte, entering service in the last months of World War I. After several fatal accidents due to wing failures, the aircraft was modified and redesignated Fokker D.VIII. Dubbed the Flying Razor by Allied pilots, the D.VIII had the distinction of scoring the last aerial victory of the war.
