Sir William Ramsay
Sir William Ramsay 1852-1916, Scottish chemist. He was professor of chemistry at University College, Bristol (1880-87), and at University College, London (1887-1912). In his early experiments he showed that the alkaloids are related to pyridine, which he synthesized (1876) from acetylene and prussi... Read more
sky
