evidence: Lewis Carroll was a pseudonym for Charles Lutwidge Dodgson, who was born in England in 1832. When he reached 18, Dodgson left home to attend Oxford University, where he stayed for the next 20 years. He was a student and then a professor and a mathematician. Dodgson created the Lewis Carroll pseudonym while he was at Oxford, so he could write children books unconnected to his academic career.
