At just 18 years and 346 days old, Nathan Thomas has become the world’s youngest male professor after landing a teaching position. Thomas, a Florida, US, resident, also shattered a Guinness World Records milestone that had remained unbroken for more than 300 years.

According to Guinness World Records, Thomas bagged a teaching role at Miami Dade College in August 2023 and began instructing students in the course COP 2270: C For Engineers. At the time, many of his students were the same age as him.
