Hasselmans was born in Liège, Belgium. He studied initially at the Conservatory in Strasbourg, which was led since 1854 by his father Joseph Hasselmans (1814–1902). He continued his studies with Gottlieb Krüger (1824–1895) in Stuttgart and with Ange-Conrad Prumier (1820–1884) in Paris. He began his performing career in the orchestra of the Théâtre Royal de la Monnaie in Brussels. A series of eight solo concerts in Paris in 1877 resulted in contracts for performances as a soloist with several Paris orchestras.
Hasselmans composed several dozen original solos for harp, of which his most famous is a concert étude entitled La Source (The Wellspring), Op. 44. He transcribed numerous works for harp originally written for other instruments by other composers, and edited important collections of studies by the earlier 19th-century harpist Nicolas-Charles Bochsa.
