Whose research revealed the element krypton?

Krypton was discovered in 1898 by William Ramsay and Morris Travers as they worked through the remaining gases of liquid air. Its name comes from the Greek word for “hidden,” reflecting how difficult it was to detect. Krypton joined neon and xenon as part of the noble gas family, helping establish a new group in the periodic table. Although rare, krypton has since become useful in lighting and some specialized lasers.
