Ferdinand Frederick Henri Moissan (September 28, 1852, Paris–February 20, 1907) was a French chemist who won the 1906 Nobel Prize in Chemistry for his work in isolating fluorine from its compounds.

He published his first scientific paper about the carbon dioxide and oxygen metabolism in plants with Dehérain in 1874.
Afer Moissan received his Ph.D. in 1880, his friend Landrine offered him a position at an analytic laboratory.
During the 1880s Moissan was focused on fluorine chemistry and especially the production of fluorine itself.
The following years till 1891 he focused on the research of fluorine chemistry.
He discovered numerous fluorine compounds, for example together with Paul Lebeau SF6 in 1901.
He was awarded the Nobel Prize in 1906.
He died suddenly in Paris in February 1907, shortly after his return from receiving the Nobel Prize in Stockholm.
