Sarah Winchester

Sarah Lockwood Winchester (née Pardee; c. 1840 – September 5, 1922) was an American heiress who amassed great wealth after the death of her husband, William Wirt Winchester. Her inheritance from his estate included USD$20 million (equivalent to $507,172,414 in 2017) as well as a 50% holding in the Winchester Repeating Arms Company, which made her one of the wealthiest women in the world at the time. She is best known for using her vast fortune to continue construction on the Winchester mansion in San Jose, California, for 38 consecutive years.^[2] Popular legends, which began during her lifetime, held that she was convinced she was cursed, and the only way to alleviate it was to add on to her California home. Since her death, the sprawling Winchester Mystery House has become a popular tourist attraction, known for its staircases that lead to nowhere and its many winding corridors.
