Dr. Henry Deacon
Dr. Henry Deacon is the town jack-of-all-trades. Although, like most residents of Eureka, he is a brilliant multi-disciplined scientist, Henry has ethical objections to the kind of research conducted at Global Dynamics, preferring employment as the town's mechanic. Henry's assistance is often invaluable in defusing the situations the experiments in town create. During Season 3, he was elected Town Mayor as a write-in candidate.

Henry: It's built on the principle of the Einstein-Grant Bridge.
Carter: The bridge device? There's the gift that keeps on giving.
