So far, Bhabha's work had been supported by the Senior Studentship of the 1851 exhibition, which he had received for three years, starting in 1936, while continuing to be based in Gonville and Caius College. In 1939, Bhabha was awarded a Royal Society grant to work in P. M. S. Blackett 's laboratory in Manchester. However, when World War II broke out, Bhabha found himself unable to return to England to take up the assignment.
