Gustav de Vries's name is well known to mathematicians because of the work of his doctoral dissertation which contained the Korteweg-de Vries equation. However, few know anything else about de Vries. We begin by giving some details about his family.
Gustav was the son of Rubertus Jan de Vries (1821-1909), an Amsterdam bookseller, and Henriette Auguste Frantzen (1826-1886). Rubertus and Henriette de Vries were married in 1857. They had seven children. Jan de Vries (1858-1928), the eldest child, studied mathematics and was awarded his doctorate in 1881 by the University of Amsterdam for his thesis Bolsystemen. He was a classical geometer who, after teaching at secondary school level in Kampen and Haarlem, taught at a technical college in Delft. He was professor of geometry at the University of Utrecht from 1897 to 1928. The other children of Rubertus and Henriette de Vries were: Auguste Pauline de Vries (1859-1863); Atje Trijntje Petronella Johanna de Vries (1861-1919); Johann Peter August de Vries (1863-?), who became Secretary-General in the Department of Finance and Privy Councillor Extraordinary; Henriette Cornella Pauline de Vries (1864-?); Gustav de Vries (the subject of this biography); and Emma de Vries (1868-1923).
After high school studies in Amsterdam, Gustav de Vries entered the University of Amsterdam where he was taught by the professor of physics Johannes Diederik van der Waals and the professor of mathematics Diederik Johannes Korteweg. He was also taught by Willem Henri Julius (1860-1925), a physicist who was one of the first to undertake research on the sun, and Adrianus Jacobus van Pesch (1837-1916), an applied mathematician who had been the thesis advisor of Gustav's brother Jan de Vries. After completing his undergraduate studies, Gustav de Vries worked for a doctorate under Korteweg's supervision. He earned sufficient money to make this possible by teaching at the Koninklijke Militaire Academie (Royal Military Academy, Netherlands) during 1892-1893. The Academy, located in the castle of Breda, trained officers of the Dutch Air Force and the Dutch Army and had not been operating for long when de Vries began to teach there. In the following academic year, 1893-1894, de Vries again taught at a military school, this time at the Cadet School at Alkmaar.
Not everything went smoothly for de Vries, however, as can be seen from a letter that his thesis advisor Korteweg sent him in October 1893 (see ):-
To my regret I am unable to accept your dissertation in its present form. It contains too much translated material, where you follow Rayleigh and McCowan to the letter. The remarks and clarifications that you introduce now and then, do not compensate for this shortcoming. The study of the literature concerning your subject-matter must serve solely as a means for arriving at a more independent treatment, expressed in your own words and in accordance with your own line of reasoning, prompted, possibly, by the literature, which should not be followed so literally. When you have mastered your subject-matter to the extent that you can do this, then naturally you will also be confronted with the questions raised by Rayleigh and McCowan, which will provide you with the opportunity to display your strength. In order to facilitate your progress, I send you the outline of a treatment of a single wave according to a slightly modified method due to Rayleigh. I will see whether I can find a guiding principle to offer you for further elaboration. ... Naturally, I cannot know whether I can succeed in this. ... For an historical overview of the theory of waves, you should consult much more literature than you have done thus far, and this task will be difficult to carry out in Alkmaar. Your introduction contains too exclusively issues that one can equally well find in handbooks [Lamb and Basset]. It is obviously a disappointment for you who must have deemed to have already almost completed your task, to discover that you have apparently only completed the preparatory work. In the meantime do not be down-hearted. With pleasure I will do my best to help you mount the horse ...Now both Korteweg and de Vries were under considerable pressure at this time. Korteweg, in addition to his normal teaching duties, was head of the university during 1883-84 and working on a major address he had to give in January 1894. Around the time that Korteweg was looking at the draft of de Vries's thesis, Jan de Vries, the elder brother of Gustav, had left his position as a high school teacher of mathematics at the HBS/Handelsschool, the trade school in Haarlem, to take up an appointment at the technical college in Delft. The position at the HSB was filled by Gustav de Vries who found the position very time consuming. He had to take on this onerous teaching task and, at the same time, try to make the major improvements to his thesis that Korteweg was seeking. De Vries had studied work on the theory of waves by John Scott Russell, George Biddell Airy, John William Strutt (Lord Rayleigh), John McCowan, Alfred George Greenhill, and Joseph Valentin Boussinesq. But, as we note below, both Korteweg and de Vries failed to pay enough attention to the work of Boussinesq.
On 1 December 1894 de Vries had an oral examination on his thesis Bijdrage tot de kennis der lange golven Ⓣ which contained the famous Korteweg-de Vries equation. The results of this thesis were written up for publication in a paper authored jointly by Korteweg and de Vries On the Change of Form of Long Waves advancing in a Rectangular Canal and on a New Type of Long Stationary Waves published in the Philosophical Magazine in 1895. They found explicit, closed-form, travelling-wave solutions to the Korteweg - de Vries equation that decay rapidly. These waves take the form of one or several waves propagating with a velocity which is proportional to their amplitude. The larger waves, therefore, will overtake the smaller waves and when the collision occurs the larger wave moves through the smaller to become the leading wave, yet neither of the waves changes form during the interaction. In fact the naturalist John Scott Russell had claimed to have observed solitary waves in 1844, yet several prominent mathematicians, including George Gabriel Stokes, were convinced they could not exist. Korteweg and de Vries proved John Scott Russell was right and produced the necessary mathematical justification. We now know that this work by Korteweg and de Vries is extremely important, but sadly this was not recognised at the time and it was over seventy years before this fundamental research led to the rapidly expanding research topic of 'solitons'. However, both Korteweg and de Vries seem to have completely missed the fact that the equation, now called the Korteweg-de Vries equation, had already appeared in the work of Joseph Valentin Boussinesq. In fact the equation appears as a footnote in Boussinesq's 680-page treatise Essai sur la théorie des eaux courantes Ⓣ (1885), but this should not in any way diminish the importance of de Vries's contribution.
On 9 April 1896 de Vries was married in Haarlem to Johanna Henrietta Jacoba Boelen (1867-1937), a school teacher who taught French language and literature. Johanna had been born in Monnickendam. They had three sons and two daughters, the first child, however, dying as an infant. Although he found it difficult to work in his home at Ripperdapark 45, de Vries published two further papers in 1900. These concern cyclones and were published in the Proceedings of the Royal Netherlands Academy. However, despite many attempts, he failed to get a better position for himself. Although at first his teaching at the five-year HBS had gone well, things began to go much less well and de Vries felt that he was not getting the support that he deserved from his principal. The stress caused but his lack of success led to him spending five weeks in 1902 in a sanatorium for patients suffering from a nervous breakdown. This was not an isolated event for the HSB annual reports of 1902, 1903 and 1904 all note that de Vries had been "absent for a considerable period because of illness". In 1907 he published a Concise textbook on arithmetic and algebra. In early 1908 de Vries submitted a manuscript to Nieuw Archief voor Wiskunde and, in April of that year, the editor of the journal, Jan Cornelis Kluyver (1860-1932), who was the professor at the University of Leiden working on analysis, differential geometry and number theory, replied to Korteweg (see ):-
I have perused the strange piece by Mister De Vries. It gives me the impression that the author has accidentally noticed a quite natural and unexceptional phenomenon, of whose true nature he makes no correct representation, and now more or less raises the status of what actually amounts to a commonplace thing to a miracle. ...Korteweg showed this letter of rejection to de Vries and this was yet another blow to add to his unhappiness. A few months later, in August 1908, de Vries wrote an open letter to Thiel, the Alderman of Education in Haarlem :-
In this letter he writes about his frustrations and lack of support from his superior, and interestingly states: "[this] added to the grief, caused by the sudden death of a child". The disappointments came in the first place, which says something about the immensity of his frustration. From the documents it appears that De Vries perhaps made too high demands on his pupils in the higher classes, but that he did distinctively well in the lower ones. This signifies that he as yet did not expect much from the younger students, but that he perhaps looked for spiritual affinity with the older ones. At the time when he was required by his director to teach below his level of qualification, he applied to all kinds of positions, but did not even get nominated. All exceedingly frustrating. Also, from the long, even printed, open letter to the Alderman it appears that there were many colleagues who found him socially incompetent in dealing with punishing pupils, but also in regard to teaching itself. The picture is that of a man with considerable communication problems.The suggestion that he was much more successful with the lower classes than with the higher ones is born out by the fact that in 1909 he was transferred from the five-year HBS in Haarlem to the three-year HSB in the same city. This lower level school made much less demands on de Vries and his situation seems to have improved. In each of the three years he taught for seven hours a week using his own textbook which he had published in 1907 and also Leerboek der vlakke meetkunde Ⓣ written jointly by his brother Jan de Vries and Willem Henrik Leonard Janssen van Raaij (1862-1937). In addition to teaching mathematics, he also taught accounting. That his life was now more stable is shown by the fact that, in 1912, de Vries published two further papers on his 'calculus rationis' in the Proceedings of the Royal Netherlands Academy of Sciences. De Vries taught at the three-year HBS in Haarlem until he retired in 1931, when he reached the age of 65. However, he developed new interests in freemasonry and spiritualism. He joined the Freemason Lodge 'Vicit vim virtus' in 1913, becoming its Master in 1916. Later that year he transferred to the new Lodge 'Kennemerland'. He took a very active part in this Lodge, holding high-powered discussions on philosophy. He also entered a long and deep discussion concerning Goethe's Faust.
In December 1934 he attended a séance in Haarlem-Noord. Leaving the séance to return to his accommodation he was knocked down by a car. He was taken to hospital where he died three days later. His wife Johanna, who like her husband had long suffered from poor health, survived her husband by three years. Bastiaan Willink, who is related both to Korteweg and to de Vries, gives the following assessment of de Vries's contributions :-
He was a decently good researcher, who however with his doctoral dissertation straightaway produced his most significant achievement. Either directly or indirectly, this must have been owing to the pressure put on him by Korteweg and to his experiencing his teaching obligations as onerous.In April 1995 an International Symposium was held in Amsterdam:-
... to commemorate the centennial of the equation by and named after Korteweg and de Vries.
