@FlyFoy,
Dickens was not antisemitic - far from it! However, he did use a commonplace caricature of the 1830s of Jews as "mysterious", "strange", "the other" - because the ambivalent & sinister character "Fagin" demanded such. Ironically, by this time in England Jews had been emancipated & , therefore, Dickens probably felt it "safe" to make Fagin a Jew: had he made him Italian (the ethnicity of most "gangmasters" of the London underworld of the time) there was a risk of provoking an anti-Italian populist backlash, whereas a Jew was a safe bet because they were generally well regarded. NB Britain's greatest C19th Prime Minister, Benjamin Disraeli, was Jewish - and a great favourite of Queen Victoria; some alleged they were lovers!
Due to criticism, & after much reflection/ soul searching, Dickens did later regret the frequent references to Fagin as "the Jew": later editions of "Oliver Twist" were, therefore, amended and 90% of the references removed & terms like "the old man" substituted. Dickens' final completed novel, "Our Mutual Friend", contains the character Riah - one of the most positive/ sympathetic portrayals of a Jew in literature: many think this was Dickens' counterpoint to Fagin; a way of balancing things up & making amends for any offence given.
BTW, Dickens sold his London house to a Jewish couple - for a lower price than he'd been offered by other prospective buyers. Why? Because he wanted the house to be owned by a family who'd fill it with children - hardly the behaviour of an antisemite!
Ref the musical "Oliver!" (loosely based on "Oliver Twist"): authored & composed by Lionel Begleiter (aka "Bart") - Jewish. First stage production, The New Theatre, London, 1960, starred Ronald Moodnik (aka "Moody") - Jewish; Lilian Klot (aka "Georgia Brown") - Jewish, and Martin Horsey - yes, you've guessed it, Jewish. Oh, and Peter Coe was also, I think, Jewish.
The whole musical is really a celebration of Cockney life/ culture in the old East End (changing rapidly by the late 1950s/ early '60s), and as everyone knows this culture was intrinsically Jewish: listen to the music, for crying out loud, its rhythm is essentially Jewish ( plus a heavy smattering of good olde music hall), and the musical's Fagin is, as Ron Moody put it, "a clown".
I do get tired of people who twitter on about "Oliver!" being antisemitic - get a clue about its origins & context, please!
