His father, Sir Anthony Alfred Bowlby, first Baronet, was surgeon to the King's Household, with a tragic history: at age five, Sir Anthony's own father, Thomas William Bowlby, (John's grandfather) was killed while serving as a war correspondent in the Opium Wars.Edward John Mostyn "John" Bowlby was a British psychologist, psychiatrist and psychoanalyst, notable for his interest in child development and for his pioneering work in attachment theory. Bowlby studied psychology and pre-clinical sciences at Trinity College, Cambridge, winning prizes for outstanding intellectual performance. After Cambridge, he worked with maladjusted and delinquent children, then at the age of twenty-two enrolled at University College Hospital in London. At the age of twenty-six, he qualified in medicine. While still in medical school he enrolled himself in the Institute for Psychoanalysis.

A child should receive the continuous care of this single most important attachment figure for approximately the first two years of life.
Bowlby (1951) claimed that mothering is almost useless if delayed until after two and a half to three years and, for most children, if delayed till after 12 months, i.e. there is a critical period. If the attachment figure is broken or disrupted during the critical two year period the child will suffer irreversible long-term consequences of this maternal deprivation. This risk continues until the age of 5.Bowlby used the term maternal deprivation to refer to the separation or loss of the mother as well as failure to develop an attachment.
