Louis Hillier (1868–1960) was aBelgian musician and composer ofWallonia, who in 1901 wrote the music of theLe Chant des Wallons, theWalloon anthem.
Among his many other compositions, he was commissioned by TheGeneral Electric Company, Ltd. (GEC of the UK, not GE of the USA) to write a company March which was performed at their 1904 Annual Dinner. It incorporated a musical part written for electric bells, still a new technology at the time.
