Armstrong, Henry Edward (1848–1937)

English chemist. His pioneering work in a number of areas of organic chemistry, included investigations into the structure and reactions of benzene and naphthalene compounds. He also speculated on the state of ions in aqueous solution.

Armstrong was born in London. He studied chemistry at the Royal College of Chemistry and began research with the British chemist Edward Frankland, but received his PhD from Leipzig in 1870 for work with the German chemist Hermann Kolbe. He returned to the UK to become professor at the London institutions which later became Imperial College, and remained there until his retirement in 1911.
