Stevenson was influenced by the strict Christian beliefs of his nanny, Cunningham, as a child.
As an adult, Stevenson was interested in the behaviour of Victorian gentlemen and the way they behaved in an outwardly respectable manner, whilst concealing their immoral behaviours.
Stevenson was fascinated by the life of Deacon Brodie, who was a respectable cabinet maker and secretly a robber.
Stevenson was born in Edinburgh in 1850.
'The Strange Case of Dr Jekyll and Mr Hyde' was published in 1886
In Victorian middle and upper-class society, respectability was valued above all. Therefore people hid their true feelings, especially those viewed as immoral or improper.
Reputation was very important to Victorian gentlemen. If they were seen doing anything that wasn't respectable, their good name was ruined.
To protect their reputations, people often kept their sinful behaviour and less respectable desires secret.
Victorian people didn't talk about anything that may damage their reputation or upset their apparently civilised society.
The 'Victorian gentleman' was an important figure in Victorian society.
Gentlemen were from the upper classes of the Victorian society.
Gentlemen had wealth, education and status. They were expected to be polite, well mannered and have high moral standards.
Army officers, church ministers, doctors and lawyers may all be counted as gentlemen.
Some middle class men such as bankers and successful merchants also aspired to be gentlemen.
In the novel, Utterson is a gentleman because he has money (he owns property), education (lawyer) and status (respectable). He is also polite, well-mannered and has high moral standards.
Jekyll is a gentleman at first - he is wealthy, educated and respected by his peers. However, when he becomes Hyde, he loses these qualities.
Being a gentleman brought many benefits such as the chance to enter well-paid professions, gain the respect of wealthy clients, and use contacts to arrange good marriages for their daughters, and well-paid jobs for their sons.
Gentlemen were obsessed with their reputations.
Gentlemen would often walk through public places to maintain their appearance as gentlemen. This happens in the book with Utterson and Enfield.
Gentlemen were expected to keep their emotions under strict control. This forced them to hide their desires for things such as sex and alcohol.
Many gentlemen were publicly snobbish about disreputable places like pubs and brothels, whilst visiting them secretly at night. Stevenson hints at this hypocrisy in the novel.
Gentlemen were prepared to pay large sums of money to keep their less respectable actions secret, which made them vulnerable to blackmail.
Even Hyde, who doesn't have a good reputation to protect, is willing to pay a sum of money to avoid a public scandal.
Whilst Utterson is keep to uncover the truth about Hyde, he does not want to damage Jekyll's good reputation.
The Industrial Revolution meant that many working-class people migrated to large towns and cities to live and work. Housing had to be built rapidly to accommodate workers and their families.
Large areas of heavily populated and poor-quality housing sprang up in London's East End, such as Soho referenced in the book.
Slums lacked basic amenities such as clean water, sewage systems or proper drainage. They also suffered from overcrowding, disease and crime.
Stevenson uses descriptions of slum areas to suggest that there are darker aspects of society hidden beneath the surface of Victorian life.
