Helium is a chemical element, and elements are discovered, not invented. Based on the provided reference, helium was discovered in 1895 by multiple scientists working independently.
The discovery of helium is attributed to:
- Sir William Ramsay in London
- Per Teodor Cleve and Nils Abraham Langlet in Uppsala, Sweden
Key Details from the Reference
The reference provides specific information regarding the discovery:
- Discovery Date: 1895
- Discovered by: Sir William Ramsay (London), and independently by Per Teodor Cleve and Nils Abraham Langlet (Uppsala, Sweden)
- Origin of the Name: Derived from the Greek word 'helios', meaning sun. This name was chosen because helium was first detected in the sun's corona.
This table summarizes the key facts about the discovery:

While helium was first detected spectrographically in the sun's atmosphere during an eclipse in 1868 by astronomers Pierre Janssen and Norman Lockyer (Lockyer is often credited with naming the element based on 'helios'), the reference specifically credits the terrestrial discovery of helium in 1895 to Ramsay, Cleve, and Langlet.
