* Thomas Green Clemson: While not strictly an *alumnus* in the traditional sense, he is the namesake of the university and considered its founder. His legacy is deeply ingrained in the institution.
* Several NFL players: Clemson has a strong football program, consistently producing players who go on to successful NFL careers. Listing them all would be extensive, but prominent examples would require knowing the timeframe you're interested in (e.g., recent players versus those from decades past). You'd need to do a more specific search for names.
* Politicians and Government Officials: Again, many have graduated from Clemson, but their fame is often regional or within specific political circles. A broad search wouldn't yield easily recognizable names to the general public.
To find specific famous alumni, you would need to refine your search criteria. For example, specifying a profession (e.g., "famous Clemson University actors") or a time period would give more targeted results. Searching the Clemson University website's alumni section would be the best place to start.
