Stephen Badlam was an American artisan and military officer. Raised in Dorchester, Massachusetts, Badlam was orphaned as a young child following the death of his father, a tavern-keeper and cabinetmaker. Badlam worked as a surveyor prior to the American Revolutionary War, where he served as an artillery commander in engagements in New York, Canada, and Vermont, serving as a major in General Richard Montgomery's ill-fated 1775 invasion of Quebec. After serving at Fort Stanwix, he fell gravely ill and was forced to return home with his wife to Dorchester.
