William Ramsay
Scottish chemist who discovered the noble gases.
Sir William Ramsay, a Scottish chemist born in Glasgow in 1852, fundamentally reshaped the periodic table by discovering an entirely new family of elements: the noble gases. After studying at the University of Glasgow and earning his doctorate in Germany, Ramsay held academic positions at Anderson College and the University College of Bristol before becoming chair of chemistry at University College London in 1887. His most famous work began after attending a lecture by Lord Rayleigh, who had noted a puzzling discrepancy in the density of nitrogen produced chemically versus that extracted from air. Collaborating, they isolated a heavy, chemically unreactive gas from the atmosphere, which Ramsay named argon, meaning "lazy" in Greek. This discovery earned Rayleigh the Nobel Prize in Physics and Ramsay the Nobel Prize in Chemistry in 1904. Ramsay then systematically investigated other atmospheric gases, working with Morris Travers to discover neon, krypton, and xenon. He also identified helium on Earth, a gas previously known only from solar spectra, and later isolated radon. His isolation of these inert gases created a new group on the periodic table. Ramsay also contributed to organic chemistry, synthesizing pyridine in 1876, and collaborated with Emily Aston on studies of mineral analysis and atomic weights. He was knighted in 1902 and served as president of the British Association. Ramsay died of nasal cancer in 1916 at age 63.

Lore & Background
Sir William Ramsay was a Scottish chemist of average height and build, with a full beard and a thoughtful, serious expression typical of late Victorian-era academics. His range of scientific inquiry spanned from organic chemistry to the discovery of an entirely new family of elements. He was born in Glasgow, the son of a civil engineer, and educated at the Glasgow Academy before apprenticing with a shipbuilder. He instead pursued chemistry at the University of Glasgow, later earning his doctorate in Germany. He held professorships at University College, Bristol, and later at University College London, where his most famous work occurred. His defining characteristic was his meticulous experimental skill, which he developed through early studies on nitrogen oxides and the synthesis of pyridine. This expertise led him to collaborate with Lord Rayleigh on a discrepancy in nitrogen density, resulting in the isolation of argon, a chemically inert gas. Ramsay then systematically investigated other atmospheric gases, discovering neon, krypton, and xenon with Morris Travers. He also isolated helium, previously observed only in the sun's spectrum, and later characterized radon. These discoveries established the noble gas group on the periodic table. He was knighted, awarded the Nobel Prize in Chemistry in 1904, and served as president of the British Association. He lived in Hazlemere, Buckinghamshire, and died of nasal cancer at age 63.
Reader's Guide
Sir William Ramsay's significance lies in his discovery of the noble gases, which fundamentally expanded the periodic table and revealed a new class of chemically inert elements. Ramsay's subsequent isolation of helium, neon, krypton, and xenon demonstrated systematic investigation of atmospheric gases, leading to the identification of an entire group of elements. His work had lasting impact on chemistry, physics, and industry, including applications in lighting, welding, and cryogenics.
