Pittman–Robertson Wildlife Restoration Act of 1937

In 1937, American hunters successfully lobbied the US Congress to pass the Pittman-Robertson Wildlife Restoration Act, which placed an eleven per cent tax on all hunting equipment. This self-imposed tax now generates over $700 million each year and is used exclusively to establish, restore and protect wildlife habitats. The act is named for Nevada Senator Key Pittman and Virginia Congressman Absalom Willis Robertson.
