For more than 25 years, John Dodge has been working with Boston’s St. Francis House , raising money and collecting clothing donations for the more than 800 poor and homeless people who rely on the shelter’s services.

On Saturday, Bedford’s 90-year-old town historian will stand at his usual spot on Great Road, in front of the Bedford Shopping Center, from 8 a.m. to dusk collecting winter outerwear to donate to the shelter.
