Hersch and Rachel landed at Grimsby on 5 April 1923. Hersch, as an alien, was issued with a certificate of registration at Bow Street Aliens Registration Office on 9 April 1923. His nationality was recorded as being Polish, evidenced by the Polish passport issued to him in Vienna on 20 July 1922. His previous Austrian nationality was also noted, as was the fact, under the heading ‘Government Service’, that he had been a private in the Austrian Army in 1915–16. His London residence was given as 19 Regent Square, WC, the first, it would seem, of a number of addresses that rapidly changed over the next few months. According to Rachel:
We moved into a bedsitting room in Regent Square – for which we paid 2 guineas a week exclusive of gas and electricity. The room was heated with gas which had a meter attached to it. A shilling in the slot heated the room for a few hours. If the hours ran out – and you were without a shilling to put in the slot – you remained in a cold room, which happened very often. Hersch was used to the cold but I, coming from a warmer climate, suffered a great deal especially from the dampness.
By 24 April 1923, they had moved to 2 Hunter Street nearby; three months later, by 29 July, Hersch's residence was noted as being at 55 Hillmarton Road, a turning off the Caledonian Road, some distance northeast of King's Cross.
