On This Day - Jan 18 : Edward Frankland was born

Frankland introduced the theory of valence when he realised that atoms can only form a certain number of bonds to other atoms. He also co-discovered helium (He), pioneered organometallic chemistry, and was a leader in the field of water purification.
