José Tiago da Fonseca Oliveira (1928-1992)

José Tiago da Fonseca Oliveira was born in Lourenço Marques (currently Maputo), Mozambique, on 22 December 1928. From early on he stood out as a good student, having won a competition of stories for young people organised by the magazine Itinerário, of Lourenço Marques, in 1945. In this same year, he won the Müller prize awarded to the best student of the Liceu Oliveira Salazar, of Lourenço Marques, for having completed his secondary education with a final mark of 19 out of 20. This won him a scholarship from the Caixa Económica Postal to go and study in Portugal. Initially he wanted to study naval engineering, however, during a stopover in Lobito, Angola, he acquired a book on statistics, which made him decide to pursue this area of study and research.

In 1947 and 1948 he completed a course in Monetary Economics, at the Associação Comercial do Porto. In 1949, he concluded a post-graduate degree in Mathematics at the University of Oporto, with a final average mark of 18 out of 20. In 1950, he completed a course in Geographical Engineering at the University with a final average of 17 out of 20.

	Tiago de Oliveira, quando era estudante

In Oporto he found an environment favourable to the development of studies and research in mathematics in a movement promoted by Ruy Luís Gomes. In the meantime, he involved himself in the political conflicts that marked the country and particularly the city of Oporto in the forties. He was a member of the M. U. D. Juvenil (Movimento de Unidade Democrática Juvenil), leaving him with some connotations related to the opposition of the regime, which would bring him a few problems in the future. He ran for the position of assistant lecturer at the Faculty of Science of Oporto and won the contest, yet his application was denied for political reasons.

In 1951, he went to Lisbon to work at the Institute of Marine Biology as a research assistant. He became involved in the literary discussions of the Sá da Costa bookshop, where he met António Sérgio (1883-1969). He was invited by Professor António Almeida Costa to become 2nd assistant lecturer at the Faculty of Science of the University of Lisbon. Meanwhile, he started publishing works on theoretic and applied Statistics, as well as on Algebra.

In 1963, he became Extraordinary Lecturer and in 1966 he became Full Professor. In the meantime, he collaborated with the magazines O Tempo e o Modo and Seara Nova, with texts that were censured several times. He started encouraging his students to study abroad with the help of scholarships. This action was decisive for the autonomisation of the Department and Centre of Applied Mathematics of the Faculty of Science. He backed the students in the academic crisis of 1962.

In the seventies, he participated in the literary discussions of the Livraria Escolar Editora, inspired to a large extent by the owner of the publishing house, Dr. Lúcio dos Santos. At this time, a controversy broke out between Tiago de Oliveira, on the one side, and António da Silveira (1904–1985) and Sebastião e Silva, on the other, in relation to the role that the University should play in the field of research. Silveira and Sebastião e Silva defended the creation of an Institute of Physics and Mathematics as an alternative to the University, while Tiago de Oliveira defended that research should be carried out within the framework of the University. Since the seventies, he had been a member of the Masonic lodge “Grande Oriente Lusitano”/ Portuguese Masonry.

In 1971-1972, he took a year’s Sabbatical leave and collaborated with the Minister of Education Veiga Simão in the teaching reform. This was a period in which the expectations of a change in politics and in the opening up of the political regime were very high. In 1972, he carried out two journeys, one to Angola and the other to Israel, where he held conferences, lectured and published works. In 1973, he associated himself to the clandestine creation of the Socialist Party. With the revolution of the 25th of April 1974 and the instauration of the democracy in Portugal, he dedicated himself to several partisan, union and university management activities. He was a founding member of the Teachers Union of the Greater Lisbon area, having formed part of the Steering Committee and presided over the General Meeting in 1975/76. From 1976 to 1978, he was a member of the government headed by the Socialist Party, occupying the position of Secretary of State for Scientific Research. This action made it possible to bring the mathematician António Aniceto Monteiro, who had been in exile since 1945, back to Portugal.

In the eighties, he defended the teaching of Statistics in secondary schools, which did in fact come about. In the meantime, the Department of Applied Mathematics of the Faculty of Science changed its name to the Department of Statistics, Operational Research and Computation. He became a member of the Academia das Ciências de Lisboa, replacing Vicente Gonçalves as an effective academic in 1985. In 1992, he became the first director of the Instituto de Altos Estudos, created within the Academia das Ciências. In 1983/1984, he created a masters degree and developed an interest for new applications of Mathematics, namely Demography and Insurance. In 1986, he spent a sabbatical semester in California, in Santa Barbara. On his return, he had his first heart attack. Since the turnabout in the eighties, he published studies on the History of Mathematics in Portugal.

In 1988, he left the Faculty of Science, forming part of the Faculty of Science and Technology of the New University of Lisbon as Full Professor, where he founded a Statistics and Actuarial Mathematics Laboratory. In 1990, he had another heart attack and on 23 June 1992, he died suddenly, also due to heart problems.


Scientific Activity

The first scientific article of Tiago de Oliveira was published in the Anais da Faculdade de Ciências do Porto under the title “Sobre o Problema da Estimação Estatística”. From this point on, he embarked on an intense research, teaching and publication activity, which made him an insurmountable figure in Portuguese science of the twentieth century. Although he had initially started out in Algebra, it was in Statistics that he played a prominent role, today being a national and international reference in the area of Statistics and Probabilities. He also carried out work in the area of the History of Mathematics in Portugal.

Frontispício da obra de Tiago de Oliveira, Statistical Analysis of Extremes

Although he dedicated most of his attention to several areas of Statistics, it was in Non-Parametrical Statistics and in Inference Statistics that he developed most of his work. Nonetheless, it was in Statistics and stochastic processes of extremes that he excelled, having been one of the main people responsible for the international development of this area of study.

His first professional occupation in 1951, after completing his university education, was at the Institute of Marine Biology, where he worked as a research assistant in Biometrics and Biostatistics. In the meantime, he pursued studies in the area of pedagogical preparation, completing the course in Pedagogical Sciences, whereupon he entered the Faculty of Science of Lisbon as 2nd assistant lecturer. He held this position from 1953 to 1957. In 1956, he applied for a PhD with the thesis Residuais de Sistemas e Radicais de Anéis, a work in the area of Algebra. While assistant lecturer, he chaired courses of Descriptive Geometry, Mathematical Physics, Advanced Algebra, Probabilities, Errors and Statistics, Advanced Geometry and Machine Design. In 1957, he defended his doctoral thesis, supervised by Prof. António Almeida e Costa. He was then promoted to 1st assistant lecturer, a position he occupied until 1965.

He lectured the subject of Logics in the Philosophy course at the Faculty of Arts of Lisbon between 1958 and 1962. In 1959, he was invited lecturer at the University of Baía, Brazil, where he lectured courses of Algebra and Mathematical Introduction to Relativity. In the academic year of 1959/60, he developed a course on the Introduction to Biostatistics at the Portuguese Society of Natural Sciences. In 1960, he spent a quarter as Senior Research Associate in the Department of Industrial Engineering, in Columbia University, in New York. In 1963, he presented his work Estatística de Densidades, Resultados Assintóticos as an aggregation thesis. In the meantime, he chaired the course of Numeric, Mechanical and Graphic Calculus, Advanced Algebra and Advanced Geometry. He supervised the Seminar on Statistics and Applications in the Centre of Applied Mathematics to the study of Nuclear Energy. At the end of 1964, he started the examinations for the position of Extraordinary Lecturer of Applied Mathematics, which he concluded in January 1965. In this same year he became Aggregate Lecturer.

In the academic year of 1966/1967, he lectured Probabilities, Errors and Statistics, Elements of Probabilities and Statistics and Mathematical Physics. He applied for the position of Full Professor of Mathematical Statistics of the Faculty of Science, a position which he occupied as from 1967. In 1969, he won the Artur Malheiros prize for Mathematical Sciences, award by the Academia das Ciências de Lisboa. He became Director of the Centre of Applied Mathematics, a position he held from 1969 to 1975. In the academic year of 1969/1970, he lectured the subjects of Mathematical Statistics, Random Dynamics of Populations, Elements of Probabilities and Statistics and Extreme Values. In the academic year of 1970/1971, he represented the Faculty of Science at the Senate of the University of Lisbon. In the same year, he lectured several subjects and held the Seminar on Statistics I and II.

In 1971, he took a year’s sabbatical, having collaborated in the educational reform process promoted by the Minister of Education Veiga Simão. In the academic year of 1971/1972, he went to Angola, where he held conferences and lectures, and to Israel, where he published some research works. In 1973, he was visiting professor at the University of Luanda. In the academic year of 1973/1974, he chaired the subjects History of Mathematical Thinking and Probabilities and Statistics, among others. In 1976, he was elected corresponding member of the Academia das Ciências de Lisboa, a position he held until 1985, when he became a permanent member. Between 1976 and 1979, he was chairman of the Institute of Portuguese Actuarial Scientists. Between 1978 and 1981, he was chairman of the Group of Applied Mathematics of the Faculty of Science of Lisbon. In 1979/1980, he was chairman of the Scientific Council of the Faculty of Science of Lisbon.

In 1982, he was invited professor in Angola and at the University of North Carolina, in the USA. In the academic year of 1981/1982, he lectured Theory of Extreme Values at the Faculty of Science. In 1984, he was awarded the Fundação Calouste Gulbenkian prize for Science and Technology, Logical and Deductive Sciences for his work. The following year he lectured the course on Statistics for Actuarial Sciences at the Portuguese Catholic University. In 1986, he spent a sabbatical semester at the University of California, in Santa Barbara, having held several conferences in different universities of the USA and in other countries, such as England, France and Belgium.

As a lecturer at the Faculty of Science and Technology of the New University of Lisbon, as from 1988/89, he lectured the subjects of Applied Statistics, History and Bases of Mathematics, Probabilities and Statistics, the Seminar on Operational Research, Actuarial Mathematics III, Mathematical Statistics, Stochastic Processes I and II and directed several seminars and probations. Over the years, he supervised and defended several doctoral thesis.

From all of his activity, of which we tried to give an overall, yet unfortunately always incomplete, picture, we would highlight, along with the various positions of pedagogical, scientific and administrative responsibility, his constant dedication to creating structures to carry out and disseminate scientific research papers in the areas in which he worked. He therefore contributed decisively to the autonomisation of the area of Applied Mathematics and of Statistics and Operational Research. He played a vital role in the creation of the Department of Statistics, Operational Research and Computation and of the Centre of Statistics and Applications. He was also the driving force behind the Portuguese Society of Statistics and Operational Research. Just as João A. Branca stated, in homage to José Tiago de Oliveira, he formed a true “School of Extreme Statistics” in Lisbon. His vast list of publications includes 9 books and over 150 papers. He also contributed towards the promotion of research scholarships and to the education and specialisation of many scholars.

He participated in numerous congresses and was a member of several national and international scientific societies, having kept up an intense research and publication activity, as can be seen from the extensive list of publications presented below. As it is impossible to present all the steps of his intensive scientific activity, we advise all those interested to consult the works indicated in the bibliography, where more detailed and complete information can be found. From the information provided below, however, it is clear to see the dimension and relevance of the work of José Tiago de Oliveira, who disappeared suddenly, interrupting several projects he still wished to develop.
