Born: July 20, 1863, Brooklyn, New York.
Died: December 5, 1924, Orange, New Jersey.
William was the son of William Neidlinger and Sara Higgs, and husband of Alice Adelaide Maxwell Sypher.
He studied with Dudley Buck and C. C. Muller in New York (1880–90).
Until 1896, he played the organ at St. Michael’s Church in New York City. He also conducted the Amphion Male Chorus and the Cecilia Women’s Chorus in Brooklyn, and the Treble Clef Club and Mannheim Glee Club in Philadelphia, Pennsylvania.
He went on to study with E. Dannreuther in London (1896–98), then worked in Paris as a singing teacher until 1901.
Returning to America, he settled in Chicago, Illinois, where for several years he was one of the most prominent singing teachers. Frank King Clark was one of his pupils and, for a time, his assistant.
The success of his Small Songs for Small Singers, a standard work for kindergartens, turned his attention to that line of composition and to child psychology, which gradually absorbed his interest to such an extent that he practically abandoned music. At one point, he established a school for handicapped children in East Orange, New Jersey.
