Many of the greatest Hispanic scientists are people you never learned about in school. From groundbreaking biologists and physicists to innovators in the fields of medicine, botany, and environmental studies, here are 10 game-changing Hispanic scientists you should know about.


Today, the world recognizes Cuban doctor and scientist Carlos Juan Finlay as a pioneer in the study of yellow fever. But back in 1881, when Finlay first presented his extensive research suggesting that mosquitoes transmitted the disease to Havana’s Academy of Sciences, he became a laughingstock. According to Finlay’s son, the speech was greeted with initial silence, followed by “universal ridicule.” It took another two decades before Finlay’s hypothesis became widely accepted. During that time, Finlay didn’t give up on his research. Instead, he spent those twenty years refining his theory, breeding mosquitoes, and conducting hundreds of tests to support this theory.


The first Mexican-born scientist to win a Nobel Prize in Chemistry, Mario Molina discovered the serious environmental threat posed by chlorofluorocarbon gases (CFCs). Along with fellow chemist Sherwood Rowland, Molina found that CFCs—chemicals commonly used as refrigerants, and colloquially known as Freon—released into the atmosphere were contributing to ozone depletion.


In 1993, astronaut Ellen Ochoa became the first Hispanic woman to go to space. She first served on a nine-day mission aboard the space shuttle Discovery, where she and a team of astronauts studied the Earth’s ozone layer, then returned to space three more times, spending nearly 1000 hours in orbit. Today, Ochoa, who holds NASA’s Distinguished Service Medal, serves as the director of the Johnson Space Center in Houston, Texas.


Nobel Prize winning biochemist César Milstein opened new doors in the diagnosis and treatment of disease with his 1975 study on monoclonal antibodies. Milstein and his team developed a technique for the unlimited production of monoclonal antibodies, a type of antibody made by identical immune cells. Thanks to Milstein’s work, monoclonal antibodies are now used in everything from diagnostic tests to the treatments of several autoimmune diseases.


Astrophysicist France A. Córdova is the director of the National Science Foundation, a federal agency that develops programs to advance all fields of scientific discovery. She was nominated for the position in 2014 by President Barack Obama. Before she spent her days overseeing America’s science and scientific education programs, Córdova conducted important research on x-ray and gamma ray sources, accretion discs, and black holes, publishing more than 150 scientific papers. Back in 1993, she also became the first woman to hold the position of NASA Chief Scientist.


Mexican-American botanist Ynes Mexia discovered two new plant genera and 500 new plant species—and she didn’t even start collecting plants until she was 51 years old. Born in 1870 in Washington D.C. to a Mexican diplomat father, Mexia spent many years as a social worker before enrolling as an undergraduate at the University of California Berkeley and discovering her passion for botany. In the 1910s and 1920s, she traveled thousands of miles around Mexico, South America, and Alaska, collecting some 145,000 plant specimens in just 13 years. Today, 50 plant species are named for her.


Born in Buenos Aires in 1968, physicist Juan M. Maldacena studies the relationship between quantum gravity and quantum field theories. Currently a faculty member at the Institute for Advanced Studies, he has been awarded the Fundamental Physics Prize (2012) and appeared on the “Einstein’s Dream” episode of PBS’s Big Ideas. Maldacena’s research on the duality of conjecture was so groundbreaking, the participants of a 1998 string theory conference wrote a song to honor him called “The Maldacena” (sung and danced to the tune of “The Macarena.” It was the 1990s, after all). While much of Maldacena’s work is tough reading for non-physicists, he has also written several explanations of his work on quantum theory for general audiences, including a popular 2007 Scientific American article tantalizingly entitled “The Illusion of Gravity.”


Father of singers Joan Baez and Mimi Fariña, Mexican-American physicist Albert Baez was the co-inventor of the X-ray reflection microscope. Though he created the device, which allows scientist to examine living cells, in 1948, it’s still considered a crucial scientific tool to this day. A pacifist, he refused a series of defense industry positions during the Cold War arms race, instead conducting research and teaching physics at the University of the Redlands, Baghdad University, MIT, and Harvey Mudd College. 


Born in New York City in 1929, Puerto Rican-American pediatrician and healthcare advocate Helen Rodríguez Trías helped improve access to public health services for women and children in both the United States and Puerto Rico. She was the first Hispanic president of the American Public Health Association as well as a founding member of the Committee to End Sterilization Abuse, an organization that fought against the practice of forced sterilization. In 2001, she was awarded the Presidential Citizen’s Medal for her work on behalf of people with HIV and AIDS. 


Nuclear physicist Ted Taylor worked at the Los Alamos National Laboratory in the 1940s and 1950s, where he helped design small nuclear weapons and reactors, as well as the Super Oralloy Bomb, which was the largest pure fission bomb ever detonated. While detonating a test bomb in the Nevada desert, Taylor once suavely lit a cigarette off of the blast using a parabolic mirror.

After observing the damage nuclear weapons could do, Taylor ultimately had a change of heart. He went on to serve as a consultant to the International Atomic Energy Agency in Vienna, where he worked to develop safeguards against the use of nuclear weapons. “He was ten or twenty years ahead of the rest of us,” Freeman Dyson, famed physicist and Taylor’s colleague, once said. “I think he is perhaps the greatest man that I ever knew well. And he is completely unknown.”

The Meteoric Rise—and Tragic Fall—of NASA's Skylab

On May 14, 1973, NASA launched Skylab, the first American space station. It fell to earth six years later, burning up in the atmosphere on July 11, 1979.

Skylab itself was a heavily modified third stage of a Saturn V rocket—the same system we used to send Apollo missions to the moon. The station was huge, measuring more than 80 feet in length, with a 21-foot diameter. During launch, Skylab 1 suffered major damage to its solar array, which delayed the launch of the Skylab 2 crew (originally intended to launch the day after Skylab itself reached orbit). The Skylab 2 mission was modified to include repair work to the solar power system and installation of a solar heat shield, as the original one was lost during launch. The Skylab 2 crew launched on May 25, 1973.

The Skylab missions resulted in new information about long-term space habitation (including an awesome space shower). The first crew spent 28 days in space; the second crew more than doubled that at 59 days; and the final crew (Skylab 4) spent 84 days up there. That last record was not broken by an American for two decades. Skylab also focused on solar science, Earth science, and microgravity experiments.

Skylab was something of a bridge between the Apollo and Space Shuttle programs. Indeed, Skylab was supposed to be serviced (and its orbit boosted) by the first Shuttle, but it wasn't ready in time. Skylab's orbit decayed, eventually causing it to disintegrate and fall to Earth over the Indian Ocean on July 11, 1979. Chunks of the station made a bit of a fireworks display streaking through the atmosphere, and ultimately littered a swath of Australia. No injuries were reported from the falling debris, though media coverage of the reentry was intense.

Here's a short NASA documentary on Skylab, explaining the story of the station. Have a look:
