His mother was Savine Lenneberg, whose father, a native of Prussia, ran the Shakespeare Hotel in George Street.
Errol's father left the family to live in Western Australia, leaving his wife to raise their two young sons.
He embarked for overseas service on 10 May 1917 leaving from Sydney on the transport ship Marathon, visiting Durban, South Africa, en route to England.
In May 1918 he was wounded in action with mustard gas and was admitted to the 1st General Hospital in Le Havre, France.
After convalescence Errol was assigned to the 11th Australian Field Ambulance which took part in the final assault on the Hindenberg Line.
Errol was also recommended by Lieutenant Colonel Hugh Bennett Lewers, Commanding Officer of the 11th Australian Field Ambulance, to receive a D.S.O.
His knowledge of drill and military routine, his enthusiasm and organising ability and his unremitting industry has led me to regard him as a most invaluable Officer.
After the war he stayed in England and undertook postgraduate training at the Seamen's Hospital in Greenwich, London, returning to Australia in August 1919.
[3] He died in Brisbane on 11 February 1956 after many years of ill health, the result of being gassed during the war[3] and was buried in the Jewish section of the Toowong Cemetery.
