In July 1913, he accepted a call to become Rabbi of the West End Talmud Torah Synagogue in Soho, London, a disorganised community of working-class Jewish immigrants of Eastern European origin.

In a short span of time, Ferber successfully centralised the unorganised Jewish activities and religious life of the community into one institution.

One of the most riveting Jewish orators of his day, he preached his sermons in Yiddish, and could bring his congregation to tears of nostalgia, or “get everyone laughing within the space of two sentences".

Ferber's eldest daughter Hoda Malka (Eda) married the teacher, editor and poet Chaim Lewis.

Chaim Lewis published the prize-winning memoir 'A Soho Address' (Gollancz, 1965) and several books of poetry and was editor of The Jewish Review periodical in South Africa.

He authored of many prolific works including Lev Avot, Echod Mi Yodea, Eternal Life a handbook for the mourner, and The Animal Kingdom in Jewish Thought.
