Dobby the house-elf, best known for his complicated relationship with Harry Potter and his work with the Order of the Phoenix, died this week after receiving a fatal blow during a skirmish with infamous Death Eater Bellatrix Lestrange. His date of birth and age, like most house-elves, is undetermined.
Little is known of Dobby's early life, although records indicate that he was born into servitude and spent much of his life as a servant in the household of the Malfoy family, where cruelty and harsh treatment were everyday occurrences.
However, it is here that he became privy to Lucius Malfoy's scheme to open the Chamber of Secrets and chose to defy commonly understood house-elf law and actively work against the wishes of his master, doing everything in his power to protect Harry Potter from the trouble that awaited him back at Hogwarts School of Witchcraft and Wizardry.
Dobby's methods to save the Boy Who Lived, particularly his use of an enchanted bludger that would only target Potter during a Quidditch match, remain controversial, and there is still debate over whether or not Dobby's actions did more to help or hinder Potter in the early stages of his war against He Who Shall Not Be Named.
