After Mr. Brocklehurst’s negligent treatment of the girls at Lowood is found to be one of the causes of the typhus epidemic, a new group of overseers is brought in to run the school. Conditions improve dramatically for the young girls, and Jane excels in her studies for the next six years. After spending two more years at Lowood as a teacher, Jane decides she is ready for a change, partly because Miss Temple gets married and leaves the school. She advertises in search of a post as a governess and accepts a position at a manor called Thornfield.
The book doesn't specify if the monster was created by one man or several or how he was brought to life. I think we can safely guess that the monster was brought to life using electricity because it has such an influence on Victor. SPOILER ALERT. I would also say that is safe to say that the monster was probably created using more than one man because later on Victor tears apart/destroys the monster's companion before he completes her creation. These are just my thoughts and if anyone has anything else they would like to add please comment
