His discovery of argon was done jointly, but simultaneously and independently, with Lord Rayleigh at Terling {LINK: Terling032}. The discoveries of neon, krypton, and xenon were done in his laboratory with assistant Travers. Discovery of radon was performed by Rutherford and Soddy at McGill University in Montreal {LINK: Canada010}, but reliable density measurements were performed by Ramsay and Whytlaw-Gray. The discovery of helium was first done spectroscopically by Janssen {LINK: Paris6-230} and Lockyer {LINK: London5-035} but Ramsay verified the "hypothetical" solar element was real when he compared the spectrum with newly discovered terrestrial helium. Photographs of his laboratory and apparatus are not shown here but instead with the South Kensington Science Museum, where they are stored {LINK: London2G-570}. The bottle of cleveite from Norway from which Ramsay detected helium is on display in the Chemistry Department of University College.
