Science and technology in Venezuela includes research based on exploring Venezuela's diverse ecology and the lives of its indigenous peoples.

Major research institutions include the Central University of Venezuela and the University of the Andes, Venezuela. Notable Venezuelan scientists include nineteenth century botanist Adolf Ernst, the chemist Vicente Marcano and the botanist and geographer Alfredo Jahn (1867–1940). More recently Augusto Pi Sunyer (es) (1955), Aristides Bastidas (1980), Marcel Roche (1987) and Marisela Salvatierra (2002) have been recipients of UNESCO's Kalinga Prize for promotion of the public understanding of science.

Pehr Löfling (Tolvfors Bruk, Gävle, Sweden, 31 January 1729 – San Antonio de Caroni (Guayana, Venezuela), 22 February 1756). Swedish botanist who studied at the University of Uppsala where he attended courses taught by Carl Linnaeus. When the Spanish ambassador at Stockholm asked Linnaeus to select a botanist for service in the American colonies, the professor at once named Loefling. He went to Spain in 1751 to learn Spanish, and then embarked with other scientists for Venezuela in February 1754. In Cumana he had entire charge of the department of natural history, and was assisted by two young Spanish doctors. He introduced the first microscope in Venezuela. His prematural death was considered a great loss to natural history, and especially to botany. Linnæus believed the loss irreparable. The manuscripts of Löfling, which were found after his death, were preserved by his two assistants and Linnnæus posthumously published his Iter Hispanicum, eller resa til Spanska Länderna uti Europa och America 1751 til 1756 in 1758. Parque Löefling in Ciudad Guayana, Venezuela is named after him.

José María Vargas (10 March 1786, La Guaira – 13 April 1854, New York City) He graduated with a degree in philosophy from the Seminario Tridentino, and obtained in 1809 his medical degree from the Real y Pontificia Universidad de Caracas. Vargas was imprisoned in 1813 for revolutionary activities. Upon his release in 1813, he travelled to Scotland for medical training in the University of Edinburgh.[1] Vargas performed cataract surgery. He was one of the earliest oculists (eye surgeons) in Puerto Rico after his arrival there in 1817.[1] He returned to Venezuela to practice medicine and surgery in 1825.[1] Elected as President of Venezuela in 1835–1836 he resigned his charge in 1836. In 1839 Vargas receives from the President Paez office, an oil bottle found in Pedernales, located in the Canton of the Lower Orinoco. He submits it to various physical-chemical analyzes involved the fractional distillation and wrote a much more complete report than the "Silliman Report" which was written 16 years later and which nevertheless appears in texts, as the first scientific report on oil. His final paragraph confirms the wisdom of Vargas: "this finding is more precious and worthy of congratulation than that of the mines of silver and gold." It amazes that such phrase was written decades before the invention of the engine to explosion that uses petroleum derivatives to move all the cars and airplanes in Century XX.

Louis-Daniel Beauperthuy (Basse-Terre, Guadeloupe, France, 25 August 1808 – Demerara, 3 September 1871) was a Venezuelan-French physician who made important contributions to the study of the causes of infectious diseases such as yellow fever, malaria, and leprosy.[2][3] He was the first to systematically argue that malaria and yellow fever were transmitted by mosquitos.[4]He studied medicine at the Paris Faculty of Medicine, and obtained his M.D. in 1837. He was immediately appointed by the Paris Museum of Natural History as a "Travelling Naturalist" to work in Orinoco basin, Venezuela. He was one of the earliest scientists to observe microorganism using microscopy in relation to diseases. In 1838 he developed a theory that all infectious diseases were due to parasitic infection with "animalcules" (microorganisms). With the help of his friend M. Adele de Rosseville, he presented his theory in a formal presentation before the French Academy of Sciences in Paris. He suspected that mosquitos were the carriers of the infectious pathogens, including those of leprosy. In 1842 he worked at the Facultad Médica de Caracas (Caracas Medical School). In 1850 he became professor of anatomy at the School of Medicine of the College of Cumana.[5] He was appointed the Director of the Leper Hospital in Demerara in British Guiana, the post he held till his death.[2] By 1853, he was convinced that malaria and yellow fever were spread by mosquitos. He even identified the particular group of mosquitos that transmit yellow fever as the "domestic species" of "striped-legged mosquito", which can be recognised as Aedes aegypti, the actual vector. He published his theory in 1854 in the Gaceta Oficial de Cumana ("Official Gazette of Cumana"). His reports were assessed by an official commission, which discarded his mosquito theory.[4] A hospital in Basse-Terre, called the Centre hospitalier Louis-Daniel Beauperthuy,[6] was established in 1959 in his honour.[7]

Jose Gregorio Hernández (Isnotu, 1858 Caracas, 1919). Graduated as a medical doctor at Universidad Central de Venezuela, in Caracas. The Venezuelan government awarded him a grant to continue his studies in Europe. Hernández traveled to Paris, France, where he studied other fields of medicine such as: bacteriology, pathology, microbiology, histology, and physiology. Following his return to Venezuela, he became a leading doctor at the Hospital José María Vargas. Between 1891 and 1916, Hernández dedicated himself to teaching, medicine, and religious practice. He sought priesthood in two occasions, but his fragile physical conditions would ultimately prevent him from achieving that status. He studied at the Monastery of Lucca in Italy for ten months in 1908. In 1913, he enrolled at the Latin American Pío School of Rome to continue the priestly career, but had to return to Venezuela for health reasons. Among the scientific publications of this famous Venezuelan are The Elements of Bacteriology (1906), About the Angina Pectoris of Malaric Origin (1909) and The Elements of Philosophy (1912). Dr. Hernández treated the poor for free and even bought them medicines with his own money. One day in 1919, while bringing medicine to the home of one of his patients in Caracas, Hernández was struck by a car and killed.

Luis Zambrano (Bailadores, 1901 – Tovar, 1990) was an venezuelan self-taught inventor and mechanic. He left formal education after the fourth year of primary school, but soon began to develop an interest in mechanics, enjoying discovering for himself the speed ratios produced by connecting oranges of different diameters and rotating them by means of jets of water. These toys lead him to consider new challenges and discover of physical principles in practical ways. In his Valle Nuevo workshop, near Bailadores, he empirically and intuitively learned enough about water turbines to generate electricity and mechanics to allow him to create about 50 inventions, some of which were commissions, such as a strawberry-peeling machine and a sieve for categorising garlic, and numerous improvements to various different machines, despite having lost his right hand to a saw in an accident in 1977. In November 1984, the University of Los Andes awarded him the title of Doctor Honoris Causa "for his useful creative work", the first time that this award had been given to a country man. He was declared an illustrious son of Bailadores, and a street in this Méridan village is now named after him.

Luis Caballero Mejias (Caracas, 1903– Caracas, 1959) was a Venezuelan engineer who invented the Precooked maize flour for the arepas in the 1950s. The traditional preparation of arepa flour is very labor-intensive, requiring the pounding of maize in a large mortar. Caballero used the profits from his patent to finance a Technical Schools system. The precooked flour was later mass-produced and sold in larger quantities.[citation needed] In 1954, the Venezuelan beer and malted drinks company Empresas Polar developed an industrial production method, launching the brand Harina P.A.N. in 1960. The product rapidly gained acceptance among housewives because of the tremendous saving in labor and its high quality. The original slogan was "Se acabó la piladera", which means "No more pounding". Harina P.A.N. has remained essentially unchanged since then, as can be seen from the original advertisements.

Arnoldo Gabaldón (Trujillo, March 1, 1909 – Caracas, September 1, 1990) was a physician, researcher and Venezuelan politician. Graduated as physician in 1928 in 1930 earned a doctorate in medical sciences at the Universidad Central de Venezuela. Then in Hamburg (Germany) completed a specialty at the Institute for Maritime and Tropical Diseases in Hamburg, later traveling in 1935 to the United States as a fellow of the Rockefeller Foundation to obtain a doctorate from Johns Hopkins University in hygiene sciences with speciality in protozoology. Back in Venezuela he was appointed to head the newly created Special Directorate of Malariology within the Ministry of Health and Welfare, a position he held until 1950.[8] Under the direction of Gabaldón, Venezuela became the first contry which organized a nationwide campaign against malaria by using DDT, which led to be the first to achieve eradication of the disease in a large area extension of the tropical zone.[8] He also discovered new species of malarial parasites and devoted himself to studying the mosquito Anopheles nuneztovari, action that catalyzed the recognition of educational needs and preparing managerial staff of the Ministry of Health, through the creation of the school that bears his name in Maracay, a deep and additional contribution.[9]Between 1959 and 1964 President Rómulo Betancourt appointed him Minister of Health and Welfare and Gabaldón developed a management program influenced by his professional background grounded in medical and environmental sanitation activities throughout the country. Gabaldón authored more than 200 papers published in national and international medical journals. Gabaldón was active as an expert of the World Health Organization (WHO) in work for malaria control in countries from 5 continents.

Jacinto Convit (Caracas, September 11, 1913 – Caracas-May 12, 2014) was a Venezuelan medic and scientist, known for developing a vaccine to fight leprosy and his studies to cure different types of cancer. In 1987, he received the Prince of Asturias Award in the Scientific and Technical Research category. In 1968, Convit was elected president of the International Leprosy Association (ILA) and was re-elected in 1973.[10] In 1971, Convit was named by the WHO as Director of the Co-operative Centre for the Study and Histological Classification of Leprosy.[11] In 1976, Convit was elected Director of the Pan American Research and Training in Leprosy and Tropical Diseases.[12] He was also named president of the International Journal of Leprosy.[13] In 1987, Convit added killed Mycobacterium leprae to the BCG vaccine. The combined vaccine was tested worldwide, but was not more effective than regular BCG. A vaccine for leishmaniasis was later developed using Convit's method.[14] He also worked on oncocerosis, mycosis, and other tropical diseases.[12]In 1988, the Venezuelan government nominated Convit for a Nobel Prize in Medicine for his experimental anti-leprosy vaccine.


Marcel Roche (August 15, 1920, Caracas, Venezuela – May 3, 2003, Miami, USA) was a physician, scientist and scientific leader. Graduated in medicine at Johns Hopkins Medical School, in Baltimore in 1946, he specialized in endocrinology and nuclear medicine. Before returning to Venezuela in 1951, he carried out biomedical research for some time at the New York Institute of Public Health. In Venezuela, Dr. Roche started several pioneering works as an Assistant Professor of the Central University of Venezuela on goitre, hookworm infections and nutritional deficiencies and anaemias, especially among the poor and aboriginal people. He was founder and director of the Institute of Medical Research at the Central University, and in 1958 he also became the Secretary General of the Venezuelan Association for the Advancement of Science. Other institutions directed by him were the Institute of Neurology and Brain Investigation, reorganized in 1959 as the Venezuelan Institute for Scientific Research. He was founder and director of the Venezuelan National Council of Scientific Investigation and the magazine Intersciencia, as well as being involved in the publishing of several other scientific periodicals. Dr. Roche was also a pioneer in the area of public understanding of science and a pioneer in the production of TV programs and documentary films on many science subjects. He was very active in promoting science to the public and participated in many national and international organizations promoting science. Dr. Roche was an advisor to the WHO, UNESCO, a Governor of the International Atomic Energy Agency (1958–1960), and was a Member and President of the Council of the University of the United Nations in Tokyo, and Secretary of the Third World Academy of Sciences.

Baruj Benacerraf (Caracas October 29, 1920 – Jamaica Plain, Massachusetts, USA, August 2, 2011)[15] was a Venezuelan-born American immunologist, who shared the 1980 Nobel Prize in Physiology or Medicine for the "discovery of the major histocompatibility complex genes which encode cell surface protein molecules important for the immune system's distinction between self and non-self".[16] His colleagues and shared recipients were Jean Dausset and George Davis Snell.

Humberto Fernández-Morán (Maracaibo, February 18, 1924 – Stockholm, March 17, 1999) was a Venezuelan research scientist, renowned for inventing the diamond knife or scalpel, significantly advancing the development of electromagnetic lenses for electron microscopy based on superconducting technology, and many other scientific contributions. Dr. Fernández-Morán founded the Venezuelan Institute for Neurological and Brain Studies, the predecessor of the current Venezuelan Institute of Scientific Research (IVIC). In 1958 he was appointed Minister of Education during the last year of the regime of Marcos Pérez Jiménez and was forced to leave Venezuela when the dictatorship was overthrown. He worked with NASA for the Apollo Project and taught in many universities, such as Massachusetts Institute of Technology, University of Chicago and the University of Stockholm. In the United States he was proposed to be nominated for the Nobel Prize. He rejected the nomination because he would have had to embrace American citizenship, which he refused, wanting to maintain his Venezuelan nationality.

Gustavo Bruzual (born in Caracas, August 2, 1949)is a Venezuelan astronomer obtained his PhD degree in 1981 from the University of California in Berkeley, USA. His thesis versed on Spectral Evolution of Galaxies. Then after he joined the staff at Centro de Investigaciones de Astronomía (CIDA) in Mérida, Venezuela, where he served for more than 30 years, including 21 years as director of the center. His research is centered on evolutionary population synthesis and modeling the spectral evolution of galaxies. His work in collaboration with S. Charlot (IAP, France) has become a landmark in the field. Their three papers together have received over 6200 citations. The Bruzual and Charlot (2003) models have proven very useful in deriving the physical properties of galaxies of different types observed in large galaxy surveys like the SDSS, allowing to characterize galaxies at various redshifts as belonging to the red sequence or the blue cloud, and providing an estimate of the stellar mass and its growth rate,in these systems. Currently G. Bruzual is working on improving different aspects of stellar population synthesis, like the treatment of TP-AGB and WR stars in spectral evolution models. Actually is investigador Titular at the Centro de Radioastronomía y Astrofísica (CryA) in the Morelia Campus of the Universidad Nacional Autónoma de México (UNAM) and professor at the UNAM Graduate Program in Astrophysics.
