CLEMSON — Clemson University says it’s received some handwritten letters sent to one of its students by celebrated crop scientist George Washington Carver.

The university says the new collection that includes several photographs of Carver with former Clemson cadet Kelly E. Traynham was given to the school by Elizabeth Traynham, Kelly Traynham’s widow.

Carver wrote the letters to thank Traynham, another Clemson cadet and their instructor for visiting his research laboratory at the Tuskegee Institute in Alabama.

Carver is best known for his research on expanded uses for Southern crops like the sweet potato and peanut. In 1923, he became the first black person to speak at Clemson, addressing cadets in the old Clemson Memorial Chapel.
