Born in Poland, Bronisław Mirski (1887–1927) was trained as a violinist and conductor. Around 1915 he relocated to the United States, where he became known as Nek (or Nicholas or Nick) Mirskey and began working as a theater orchestra conductor. At first he worked in small towns including Punxsutawney and DuBois, Pennsylvania, where he met his future wife, pianist Genevieve Wilson. After their marriage in 1917, he sought work in larger cities and subsequently worked in Boston, Dallas, New York, and Kansas City.
