Creighton Carvello was called the Memory Man. He could remember hundreds of playing cards and pages of the telephone numbers in only a few seconds.

Creighton was born in India in 1944. He was the middle child of five and his father worked on the railways. In 1949, the Carvello family returned to England and settled(定居) in Middlesbrough, where Creighton spent the rest of his life. His father first noticed his great talent when, aged 7, he started to memorize information from cigarette cards with pictures of planes and cars.

After leaving school, Creighton developed his talent by memorizing more and more information. He soon became popular as he performed in clubs to show his great memory. He remembered the telephone number of anyone called Smith who lived in the Middlesbrough area. He first got into the record books in his thirties. He travelled around the world, showed up on television and amazed the audience with his memory.

Creighton was a man of many talents, including writing songs, drawing and telling jokes.

In his last years, Creightton moved to care home. The old people there would test his memory with questions such as naming what day of the week they were born on.
