Family lore was that my curmudgeon uncle Robert Heizer, who worked in the World War II Kaiser Richmond shipyards as a steamfitter, bristled at the formal security measures in the yards and pasted a photo of a gorilla on his badge. No one noticed.
Wartime vigilance was nothing to joke at, but workers did. Most of the push back was good-natured and harmless, and all of the wartime Kaiser factories only experienced a single documented incidence of outright sabotage.
This cover of the weekly Richmond shipyard magazine treats us to a young guard being surprised by the contents of an older worker’s lunchbox. Note the punched IBM computer card in his pocket.
The “On the cover” description says: “In vivid chalk and charcoal Shipfitter Sam Wainwright of Richmond Shipyard Number One portrays a not too impossible scene stemming from his intimate knowledge of the strange things that sometimes turn up in workmen’s lunchboxes."
