In the 1960s, Bob Moore read a book about an old grain mill and was inspired to start his own.

Using giant quartz stones from the 19th century, he ground and packaged dozens of different cereals and flours, quickly positioning his company at the forefront of the health food boom.

Despite a devastating fire in the 1980s, Bob's Red Mill grew into a $100 million business – and although Bob is nearly 90, he goes to work at the mill every day.
