During the First World War the RSPCA provided support for the Army Veterinary Corps in treating animals such as donkeys, horses, dogs and birds that were co-opted into military service as beasts of burden, messengers and so forth.  The RSPCA's centenary in 1924 and its one hundred and fiftieth anniversary in 1974 were accompanied by books telling the society's story.  Since the end of the Second World War the development of intense agricultural farming practices has raised many questions for public debate concerning animal welfare legislation and the role of the RSPCA. This has included debates both inside the RSPCA (. the RSPCA Reform Group ) as well as among ethicists, social activists and supporters of claims for animal rights outside of it concerning the society's role in ethical and legal issues involving the use of animals. 
Eva Smith/Daisy Renton, her first name is a bit like Eve, the first woman according to the bible. Her second name, Smith, ordinary and very common. The Inspector says 'there are millions of Eva Smiths and John Smiths still left' and their chances of happiness are 'intertwined with our lives'. The subject of the play is not Eva/Daisy; the focus of the attention is the five people sitting around the table at the beginning. Eva's looks may have been her downfall; she had big dark eyes and soft brown hair. Arthur Birling remembers her as a 'lively good-looking girl'. Sheila remembers her as 'very pretty'. Gerald remembers in the Palace bar she looked 'young and fresh and charming'. Eric remembers meeting her there too and that she 'wasn't the usual sort.' Sybil Birling doesn't say anything about her looks; she probably thinks a working class girl has no right to be pretty, based on her other views. All of Eva/Daisy's jobs got taken away from her. First, she was a factory worker at Birling and Company. A Shop assistant at Milwards, she worked there for a couple of months and Sheila got her sacked. She was a prostitute and then a mistress to Gerald. He rescued her from the life of a working prostitute and put her up in a flat, gave her money and slept with her. This made her happy, until Gerald dumped her. Eva/Daisy ended up back as a prostitute. The audience don't find out whether Eva Smith and Daisy Renton were in fact, the same person, so at the end of the play, this is what they are left thinking about. There are reasons why Gerald claims there were lots of different girls. Gerald says, 'there isn't any such inspector. We've been had.' Gerald's key point is 'We've no proof it was the same girl.' He says, for all we know, the Inspector could have shown us all a completely different photograph. Eva/Daisy never sought revenge, so the Inspector did it for her.
