[ 1690 ] English astronomer Edmond Halley—of Halley’s Comet fame—improves the diving bell. Additional air is available in weighted barrels connected to the diving bell in order to replenish the air supply. Dives of 90 minutes to depths of 18 m (60 ft) are recorded. An improved version later allows Halley to remain immersed for over four hours.
