In 1916 , Gulati became a medical officer in the Indian Medical Service after completing his medical training in Lahore . In 1919 , he was in Amritsar at the time of the Amritsar massacre . In 1920 , for reasons unknown , he worked his passage to the United Kingdom where he arrived in Liverpool penniless and walked to London . His qualifications were not recognised in the UK and therefore he repeated his further education and medical training at Charing Cross Hospital . Friendless and without money , he did unskilled work at night to pay for his studies . Eventually qualifying with LRCP and MRCP in 1926 , he entered general practice in the largely working-class district of Battersea in London
