Who was the first person to play the Harmonium?

The harmonium, as a musical instrument, does not have a singular inventor or first player, as it evolved from earlier keyboard instruments in the 19th century. The modern harmonium was developed in France around the 1840s, with significant contributions from inventors like Alexandre Debain. While it's difficult to pinpoint an exact "first person" to play it, the harmonium became popular in various musical traditions and settings shortly after its invention.
