Hispanic Scientists and Engineers
Celebrate Hispanic Heritage Month by learning more about some of the many Hispanic and Latinx scientists and engineers who have made important contributions to science history.
Hispanic Heritage Month: Scientists to learn more about!
Update! This post has been updated for 2021 to include additional scientists and engineers.
Diversity in STEM
To help students see themselves with a future in STEM and to broaden understanding of science history, it is important for students to learn about a diverse range of scientists and engineers. This includes celebrating the stories of women in science, African American scientists and engineers, Asian American Native Hawaiian/Pacific Islander scientists, scientists with disabilities, and other scientists from around the world.
In honor of Hispanic Heritage Month, we highlight a few of the Hispanic and Latinx scientists and engineers who made (and are making) important contributions to science, technology, engineering, and math (STEM). The list below is only a sampling of noted scientists through history and working in STEM fields today.
Learn More about these Hispanic and Latinx Scientists and Engineers
To encourage your students to learn more about these scientists and to explore related science projects and careers for scientists they find interesting, for each scientist, we have included a short biographical summary, links to 1-2 hands-on science projects related to the scientist's area of study, links to relevant science career profiles, and a link to a biography.
Note: Educators can use this career worksheet to guide student exploration and reflection about STEM careers.
