Lord Voldemort. When Harry was a one year old, Lord Voldemort came to his house with a plan to kill him. Lord Voldemort accomplished killing Lilly and James, Harry's parents. But not Harry. When Voldemort tried to kill him with the killing curse, It did nothing but put that scar on his head, and a part of Voldemort's soul was now in that scar.

It depends on how many one wizard or witch has. for example, Lord Voldemort had six and a seventh one he never meant to make which was Harry Potter. to be able to have a horcrux that person will have to murder others which will cause their soul to split. like Lord Voldemort, he split his soul into seven pieces. in the harry potter films, one by one they were destroyed. if a horcrux gets destroyed that witch or wizard will feel pain or die if only spliting their souls once. but Lord Voldemort as known as Tom Marvolo Riddle, was obsessed with not dying even at an early age causing him to create so many.
Voldemort creates Horcroxes by splitting his sole apart. It is a very painfull process. Voldemort had made seven Horcroxes, which ment he split his soul into seven.
