Eugène melchior peligot

Eugène Melchior Peligot (1811-1890) did research in a wide range of subjects, among them sugars and their reactions, chromium, uranium, iron, and their salts, the composition and structure of glass, the silkworm, fertilizers, and drinking water. He was the first to prepare uranium, study its properties and determine its atomic mass. Together with Dumas isolated methyl alcohol from wood spirit, studied its reactions, and introduced the term methylene in chemistry. He discovered potassium trioxochloro chromate (Peligot's salt) and its especial properties. He showed that glass must be composed of a mixture of silicates in indefinite proportions to avoid its crystallization. He obtained dichroic glass by addition of uranium oxide.
