A Nobel prize winning scientist who was born in Cambridgeshire has returned to his home town of Wisbech.
Sir Harold Kroto was visiting Wisbech Grammar School to talk to pupils.
He was awarded the Nobel Prize in 1996 for his work which led to the discovery of a new form of carbon called C60.
In the school itself there is actually a laboratory named after the scientist- the Kroto laboratory. He was born in the town back in 1939.
