The teacher of various generations of Spanish scientists and an outstanding researcher in the fields of Biochemistry, Molecular Biology and Microbiology, David Vázquez was born on the 24th March 1930 in Tucumán, Argentina, to Asturian parents.

After studying at university in Spain and England, in 1954 he graduated from the Faculty of Pharmacy of the University of Madrid with a first-class cum laude degree. In 1959 he received his doctorate in Chemistry from the University of Madrid and in 1965 from Cambridge, England, Microbiology being the main subject of his studies.

He did his first post-doctorate work in the national Institute of Agronomy in Paris, in the National Institute for Dairy Product Research in Reading, United Kingdom and at the Biochemistry and Molecular Biology Laboratory at Cambridge, United Kingdom.

In 1963 he joined the Higher Council for Scientific Research (Consejo Superior de Investigaciones Científicas - CSIC) in Spain, beginning his work in the Cell Biology Institute. As a scientific contributor, he did research work and felt the beneficial influence of other dynamic young biologists such as Alberto Sols or Manuel Losada.

His work centred, basically, on the mechanisms of biological synthesis of proteins and the action of antibiotics. regarding the latter, he carried out important research which clarified the mechanisms of the actions of various antibiotics, especially those which paralyse the protein assembly mechanisms of pathogenic organisms without affecting the host cells.

Outstanding as the main Spanish researcher into antibiotics, David Vázquez carried out practically all his scientific work in connection with the Higher Council for Scientific Research. In 1967 he was appointed as a scientific researcher, and in 1971, as a Research Lecturer of the CSIC, the highest grade which exists in this body.

From 1968 on he took charge of running the Council's Institutes of Cell Biology and Macromolecular Biochemistry, also participating on the Board of the Institute of Molecular Biology.

A numerary member of the council between 1975 and 1977, he was subsequently the founding-chairman of the Santiago Ramón y Cajal Board; president of the Spanish Society of Microbiology; lecturer and director of the Microbiology department of the Science Faculty of the Autonomous University of Madrid; president, from 1984 until his death, of the Spanish Society of Biochemistry and a numerary member of the Royal Academy of Natural, Physical and Exact Sciences.

He was, furthermore, a member of the Scientific Advisory Committee of the Juan March Foundation, a post from which he played a crucial role in promoting the activities of the Foundation in the support of Spanish science. The prestige of David Vázquez in the field of his scientific activity is universal, and he always appeared as a speaker in every congress on protein biosynthesis or the mechanisms of antibiotic action held anywhere in the world.

He himself organised international symposia in Spain. From his work on these meetings the results were some hundred lectures given, among others, at the annual congresses of the European Federation of Societies of Biochemistry and World Biochemistry Congresses. He was, likewise, the author of more than 260 research works published in major Spanish and international journals.

He died in Madrid on the 15th February 1986. The Higher Council for Scientific Research, the Asturian School of Hispanic Studies and the "San Pedro" Festival and Cultural Society of La Felguera, among other bodies and associations, paid posthumous tribute to him. In his memory, a monument has been raised in the Plaza Sesta, in La Felguera, the Asturian town where his family came from.
