Picadilly Jim oder Picadilly Browne war Jim Browne, an den sich George Moore folgendermaßen erinnert: »Jim was now my mentor, my hero, my boon companion. It was my pride to be seen in Picadilly with this fine Victorian gentleman, whom I recall best on a wintry day; he never wore an overcoat, but buttoned his braided coat tightly about him and swung a big stick. Long flaxen locks fell thick over his collar, and his pegtops blew about in the wind; he was known to everybody as Picadilly Jim or Picadilly Brown. Jim saluted his acquaintances with a How are you? never a How do you do?
