Toggle harpoon head for whaling

Portraits are AI-generated interpretations, not photographs.
Impact on the world
His toggling harpoon design (the 'Temple toggle iron') dramatically improved the efficiency and safety of whale hunting and became standard equipment across the whaling industry.
Life & background
A blacksmith and abolitionist, Temple invented the toggling harpoon head, a design that allowed whalers to secure a catch far more reliably than earlier harpoons. Despite never patenting it, his design became the industry standard.
