1625 – First description of hydrogen by Johann Baptista van Helmont.First to use the word "gas". 1650 – Turquet de Mayerne obtains a gas or "inflammable air" by the action of dilute sulphuric acid on iron.
Hydrogen gas was first produced artificially in the early 16th century by reacting acids with metals. Henry Cavendish, in 1766–81, identified hydrogen gas as a distinct substance [16] and discovered its property of producing water when burned; hence its name means "water-former" in Greek.
Henry Cavendish FRS (/ ˈ k æ v ən d ɪ ʃ / KAV-ən-dish; 10 October 1731 – 24 February 1810) was an English-French experimental and theoretical chemist and physicist.He is noted for his discovery of hydrogen, which he termed "inflammable air". [1]
Obtained by irradiating uranium with neutrons, it was the first transuranium element discovered. [179] Shortly before that, Yoshio Nishina and Kenjiro Kimura discovered the uranium isotope 237 U and found that it beta decays into 237 93, but were unable to measure the activity of the element 93 product because its half-life was too long.

Cavendish discovered hydrogen as a colorless, odourless gas that burns and can form an explosive mixture with air, and published a paper on the production of water by burning inflammable air (that is, hydrogen) in dephlogisticated air (now known to be oxygen), the latter a constituent of atmospheric air (phlogiston theory).
