A my Wyss is an American heiress and philanthropist whose fortune originates from Synthes, a medical device company that was founded by her father, Swiss billionaire Hansjoerg Wyss. Synthes became a global leader in producing internal fixation devices, such as plates and screws, used to treat bone fractures. The company's success made her father one of the wealthiest people in the world.

In 2012, her father sold Synthes to the healthcare giant Johnson & Johnson for a staggering $20.2 billion in cash and stock. Amy Wyss, who had worked at the company in various roles, received a significant portion of the proceeds from the sale, making her a billionaire in her own right. She has since dedicated herself to philanthropy, focusing on conservation, environmental issues, and community initiatives, primarily in the western United States. She co-founded the LOR Foundation, which supports rural communities in the Intermountain West.
