Miguel de Guzmán Ozámiz was born on January 12, 1936 in Cartagena (Murcia, Spain) into a family of navy officers surrounded by tragic events: his father was executed with 157 other navy officers during the Spanish Civil War, when Miguel de Guzmán was only six months old.

He studied industrial engineering from 1952 to 1954 in Bilbao (Vizcaya) but before completing his studies he entered the Jesuit order and studied humanities and classical arts from 1954 to 1958 in Orduña (Vizcaya); he then went to Germany, where he studied philosophy in Munich until 1961, in the Berchmanskolleg.

Miguel de Guzmán returned to Spain where he decided to study mathematics because he could achieve "a solid knowledge, without opinions, that you handle and gives you a sure domination over the world and the nature" and also to find "a sense of beauty that attracts you". As he wrote in a text posted on his website, "Elementary geometry was the great hobby that attracted me to the study of mathematics and has remained with me throughout my life."

He completed studies in mathematics at the University of Madrid in 1965, and also became interested in the didactics of mathematics because of the "humanistic and communicational aspect that can be done with mathematics".

He went to study analysis in Chicago after a visit of Alberto Calderón to Spain in that year and in 1968 he obtained a Ph.D. in mathematics (his doctoral dissertation was on singular integrals with generalized homogeneity) at the University of Chicago under Calderón's supervision. After earning his Ph.D. he became a professor at Washington University in St. Louis (1968-69), calling this "an immensely productive year in which I took contact with many active colleagues in the field of analysis."

In 1969 Miguel de Guzmán returned to Spain and became a Professor of Mathematical Analysis at the Universidad Complutense de Madrid, where he remained from then on, except for a period of two academic years (1982-1984) when he held a position at the Universidad Autónoma de Madrid. By this time he had left the Jesuit order because he thought he could do what he wanted to do better outside the order, but he maintained excellent relations with other Jesuits.

In 1971 he married Mayte Garcia-Monge and had two children: Miguel, an architect and Mayte, a physician.

In 1982 he was named a member of the Spanish Royal Academy of Mathematical, Physical and Natural Sciences, an institution where he started an ambitious program aimed at the detection and stimulation of mathematical talent in students in elementary and secondary schools. He served as president of the International Commission on Mathematical Instruction (ICMI) from 1991 to 1998, where he initiated a very important solidarity program and strongly advocated an international cooperation between mathematics researchers and researchers in mathematics education.

According to Spanish mathematicians, Miguel de Guzmán was a key figure in Spanish mathematics of the twentieth century. Eugenio Hernández and Fernando Soria wrote in the ICMI Bulletin (no. 54, June 2004) that Miguel de Guzmán was

a central figure in the development of harmonic analysis in Spain and (…) captivated the enthusiasm of several generations of mathematicians. He was an extraordinary teacher and communicator and his ideas in mathematical educationHis Internet page, constructed immediately after his department opened its server, contains numerous texts (mostly in Spanish, with a few in English) and will be maintained by his university as a tribute to its author. It can be seen at: http://ochoa.mat.ucm.es/~guzman/

have had a profound influence on the teaching of mathematics in Spain and in the world. His books, translated into several languages, have made accessible to a large audience that extraordinary activity of the human spirit known as Mathematics.

Miguel de Guzmán's commitment to education began very early and permeated all of his activities. He not only said that "teaching in any form is very attractive" but also that the "nature of the mathematical task makes it capable of stimulating important ethical aspects that we should foster in ourselves and that we should try to instil in any healthy educational system of our times."

Miguel de Guzmán thought we should have a "broad vision" of what mathematics is and reject the "somewhat empty routine" that mathematics so many times seems to entail in the classroom. He believed that mathematics is a way to understand the harmony of the universe, a science that seeks the truth, a tool that other sciences use, a creative activity with a beauty that, to use Plato's words, can only be seen with the eyes of the soul. These facets of mathematics are profoundly human and should make mathematics into one of the great axes of our educational system, if teachers are well prepared for that task; he also believed that we are failing in the preparation of mathematics teachers at all levels. In the text "Innovative trends in mathematics education" (reference?) he presented aspects that should be considered in order to change the situation, such as the exploration of applications, games, etc., and he also discussed the impact of calculators and computers, and of new areas such as discrete mathematics, etc. One of the aspects he emphasized the most is the role of history of mathematics. He maintained that history of mathematics is an important aide in:

- giving an idea of how peculiar the surge of mathematical ideas is;
- fixing the period and place of significant ideas and problems, along with their motivation;
- identifying the open problems in each period, their evolution, and how they stand at present;
- pointing out the historical connexions of mathematics with other sciences, whose interaction traditionally produced a large number of important ideas.

As a mathematician, he tried to convince all other mathematicians to become involved in the troubled waters of mathematics education. In 1996 he gave a talk at the 8th International Congress on Math Education (ICME 8) entitled "On the role of the mathematician in Mathematics Education", in which, admitting that "mathematical education is a rather complex task", he claimed that all mathematicians should "collaborate together in order to face its many difficult problems with efficiency", promoting "a global vision of mathematics in human culture". In this respect, mathematicians should devote their effort to several projects, namely:

- pre-service and in-service preparation of teachers;
- research in mathematics education;
- mathematics education;
- educational treatment of young talent in mathematics.

In order to keep the ideas and the example of Miguel de Guzmán alive, the RSME, the Spanish Royal Mathematics Society, decided to launch a Summer School of Education aimed at secondary school teachers of mathematics. The first such school was held in 2005 in El Pazo de Mariñán (Bergondo, La Coruña) with the title "Computers and Mathematics Education"; the sixth was held in 2010 in the University of Burgos with the title "Contextualizing Mathematics".
