Guinness World Record: Meet Nathan Thomas, the world’s youngest professor at 18

Nathan Thomas, an 18-year-old engineer from Florida, has shattered a 306-year-old Guinness World Record by becoming the world's youngest professor. Teaching engineering at Miami Dade College, Thomas was recognized by Guinness World Records in July 2026 for his record-breaking achievement. Born in Florida, Thomas began his academic journey at Miami Dade College when he was just 10 years old, thanks to a dual-enrollment program.

By the age of 14, he had transferred to Florida International University, where he completed his bachelor's degree in electrical engineering at the age of 16. Two years later, he earned a master's degree, achieving both degrees with the highest honors.

Thomas's fascination with STEM subjects was nurtured by his parents, both engineers, who made learning feel accessible and engaging. His mother's unique ability to demystify complex concepts played a significant role in igniting his passion for engineering. Thomas's teaching journey started quietly in August 2023, but Guinness publicly acknowledged his historic milestone in July 2026, generating global interest.

One peculiar aspect of his teaching role is that some of his students were the same age as he was when he started teaching.

Breaking the record held by Scottish mathematician Colin Maclaurin, who became a professor at 19 in 1717, Thomas also surpassed the previous female record-holder, Alia Sabur, who achieved professorship at 18 years and 362 days in 2008. However, Thomas seems more focused on the learning experience than on his age. He stated to Guinness World Records that "once you’re in that setting, everyone’s there for the same reason, which is to learn," emphasizing that age doesn't matter in that context.

Thomas's story is one of early academic success and the supportive environment that fostered his curiosity. His parents' encouragement and his own innate interest in science, technology, engineering, and math (STEM) propelled him to achieve remarkable milestones at a young age. Despite his record-breaking accomplishment, Thomas remains humble and focused on teaching rather than accolades.

Currently a law student at the University of Miami School of Law, Thomas plans to merge his legal expertise with his STEM background. His message to young people is to avoid comparing their progress to others, encouraging them to pursue their goals at their own pace.
