PETERSILEA, Carlyle, musician, born in Boston, 14 January, 1844. He received his first musical education from his father, and in 1862 went to Germany, where he studied for three years at the Leipsic conservatory. He was graduated with honor, and then made a professional tour of Germany, meeting with great success. On his return to this country he settled in Boston, where, in 1871, he founded the Petersilea academy of music, elocution, and languages, which existed until 1886, since which year he has taught in the New England conservatory of music. He has at various times appeared as a soloist in Germany and the United States, and is known for his technique and memory. He is the author of an original piano system. His work as a composer is limited to some transcriptions of songs, his technical studies, and a few unpublished string quartettes and sonatas. He has also invented a mute piano for practice.
