Pierre Janssen discovered helium in 1868 during a solar eclipse.

Norman Lockyer and Edward Frankland named the element "helios" which is the Greek word for "Sun" since it was first seen in the chromosphere in the Sun.

Common uses of helium:

-read barcodes with a helium-neon laser in a scanner
-condense hydrogen and oxygen to make rocket fuel
-fill balloons
-detect leaks in ships
