Scores of employees gathered to help Bob Moore celebrate his 81st birthday this week at the company that bears his name, Bob’s Red Mill Natural Foods.

Moore, whose mutual love of healthful eating and old-world technologies spawned an internationally distributed line of products, responded with a gift of his own — the whole company. The Employee Stock Ownership Plan that Moore unveiled means that his 209 employees now own the place and its 400 offerings of stone-ground flours, cereals and bread mixes.
