Henry Krumb (1875–1958) was an American mining engineer. As a Guggenheim engineer, he was the first to apply scientific methods to sampling bulk-tonnage orebodies at the enormous porphyry copper deposit at Bingham Canyon, Utah. Krumb further refined his churn drill sampling technique at William Boyce Thompson's Inspiration (Miami, Arizona) mine. He also developed the nearby Magma Mine at Superior, Arizona for Thompson. Thompson then built a winter home and gardens nearby, now open to the public as the Boyce Thompson Arboretum, the oldest public botanical garden in the Western US.
