Yes, and it was discovered (and later isolated) by separate, independent scientists. Helium was discovered by the French astronomer Pierre (Jules) Janssen during a total solar eclipse in Guntur, India, in 1868.

In 1895 Sir William Ramsay separated helium from air in the laboratory; the same year this experiment was repeated independently by Per Theodor Cleve and Nils Langlet in Sweden.
