Kay was born in
Northampton in 1939 to Tony Chambers, a manager at a washing machine company, and Eva Gertrude Pearcey, a dressmaker. When he was young, his parents divorced and his mother remarried Harry Kay, a Jewish businessman in London. Barry later described his childhood in a memoir titled,
Whatever Happened to Barry Chambers?, where he recalls his transformation from "Barry Chambers" into "Barry Kay". He boarded at
The King's (The Cathedral) School and went on to study medicine at the
University of Edinburgh, graduating in 1963. ==Career==
