Hirsch became a journalist, writing a scientific column. His wife, who he married in 1928, was Jewish and he adopted the faith for her sake. He had little choice but to leave for England (where he had distant relatives).
Despite having a doctorate, he completed a second one at Cambridge on polycyclic groups under Hall's supervision. Appointments to Leicester and Durham followed (he won county chess championships in both places). Then in 1951 he was appointed to London where he remained building up a strong algebra school.
All Hirsch's publications were in group theory, in addition to the work on polycyclic groups he published on locally nilpotent groups and automorphism groups of torsion free abelian groups.
