So I submit to my colleagues here today that hydrogen is not as far away as we think it is.

- Bob Inglis

Birds are, especially canaries, are super sensitive to hydrogen sulfide and sour gas.

- David Suzuki

Had we not pursued the hydrogen bomb, there is a very real threat that we would now all be speaking Russian. I have no regrets.

- Edward Teller

Gaseous nitrogen combines with gaseous hydrogen in simple quantitative proportions to produce gaseous ammonia.

- Fritz Haber

It has long been known that the chemical atomic weight of hydrogen was greater than one-quarter of that of helium, but so long as fractional weights were general there was no particular need to explain this fact, nor could any definite conclusions be drawn from it.

- Francis William Aston

As early as 1912, we worked on the problem of the hydrogenation of organic substances with the aid of highly compressed hydrogen.

- Friedrich Bergius

Big Bang gave us hydrogen and helium. We couldn't make people out of hydrogen and helium. So we're made out of exploding stars.

- John C. Mather

I don't believe that a hydrogen economy depends on a carbon economy at all.

- Larry Burns

And I also take photos of hydrogen bomb, from another part of the building. It was not part of my job, but I succeeded to go and take photos of the hydrogen bomb.

- Mordechai Vanunu

I also was producing, working on other materials for the hydrogen bomb. They call it lithium-6 and tritium. I was working on these and the only use for lithium-6 is the hydrogen bomb.

- Mordechai Vanunu

In organic chemistry, we have learnt to derive from compounds containing only carbon and hydrogen, i.e. from the hydrocarbons, all other types of combinations, such as alcohols, aldehydes, ketones, acids, etc.

- Otto Wallach

Three-fourths of the universe is hydrogen, and oxygen is incredibly abundant, too. So H2O is something you can find nearly everywhere.

- Seth Shostak

After earning my Ph.D., I stayed at the Max-Planck Institute as a postdoc, working on laser excitation of Rydberg states of triatomic hydrogen and helium hydride. I also succeeded in analyzing all the emission spectra of helium hydride, which I had discovered during my Ph.D.
