If anyone is in London for a visit, I highly recommend the walking tours of the Old Jewish Quarter with a gentleman named Stephen Burstin. My husband and I took a tour arranged by JW3 (see link below) which is a marvelous London Jewish Community Center. Our tour focused on just one section of London, but in that two hours we learned so much about the Jewish immigrants  from eastern Europe and Spain/Portugal, and walked through the streets where they lived, went to school, worked and worshipped. My husband and I were deeply moved.
