Sometime later in 1869, vanadium metal was isolated from its ores by Henry Enfield Roscoe (1833—1915), but Sefstrom had already received credit for the discovery of the element vanadium. 

The final step in the discovery of vanadium was accomplished by the English chemist, Sir Henry Enfield Roscoe, who was bom in London on January 7, 1833. When he was nine years old the family moved to...

From Thorpe s The Right Honourable Sir Henry Enfield Roscoe ... 

Both Sefstrom and del Rio saw vanadium only in the form of a compound, vanadium pentoxide (V2O5). It is very difficult to separate pure vanadium metal from this compound. It was not until 1887 that pure vanadium metal was isolated. English chemist Sir Henry Enfield Roscoe (1833-1915) found a way to separate pure vanadium from its oxide. 

Berzelius, Johnston and others tried in vain to isolate the metal itself. The substances they thought were metallic vanadium, obtained by reduction of vanadium oxide with carbon or potassium, or of vanadium chlorides (VCI3, VOCI3) with potassium or ammonia, all turned out to be carbides, silicides, nitrides (VN) or low-valent oxides (VO).[ l The first apparently successful generation of metallic vanadium was accomplished by Sir Henry Enfield Roscoe in 1869 by reduction of VCI2 with hydrogen in a lengthy experiment [ 1... 

The South Kensington Museum was renamed the Victoria and Albert Museum in 1899, when Queen Victoria laid the foundation stone of the new building for the art collections. By what seems to have been a bureaucratic oversight, the Science Museum was considered a division of the Victoria and Albert Museum. In 1909, the famous chemist and politician Sir Henry Enfield Roscoe led a delegation of scientists and engi-... 

Sir) Henry Enfield Roscoe (London, 7 January 1833-Leatherhead, Surrey, 18 December 1915), who came of a famous Liverpool family, was first educated there, then studied at University College, London, under Graham and Williamson (1848-53), and then with Bunsen in Heidelberg on the photochemical union of hydrogen and chlorine (from 1855, see p, 721). He succeeded E. Frankland as professor in Owens College, Manchester (later the University of Manchester) in 1857, private laboratory in...
