Sir Edmund Halley, the renowned astronomer, invented an ingenious diving
bell in 1691 to explore underwater realms. Frustrated by shallow dives, he
engineered a wooden, open-bottomed barrel weighted with lead, replenished with
air via weighted barrels lowered from the surface. This allowed divers,
including Halley himself, to descend over 60 feet into the Thames for up to 90
minutes. His bell aided salvage operations, like recovering cannons from
wrecks, and inspired future submersibles. Halley’s design proved air could be
supplied underwater.
