(CNN)Alan Naiman was known for his frugality — he wore Costco jeans, bought his favorite pocket T-shirts at a grocery store and squirreled away every penny he could. So when he died, friends were surprised to learn that he had left more than $11 million to charities in the Seattle area.
The 63-year-old never married and never had children, but kids were very important to him. He fostered a few children and cared for his brother, Daniel, who had developmental disabilities.
Naiman became a social worker after leaving a career in banking.
