Robert Holford Macdowall Bosanquet (original) (raw)
Robert Holford Macdowall Bosanquet (* 31. Juli 1841 in Rock Hall bei Alnwick, Northumberland; † 7. August 1912 in Castello Zamorra, Teneriffa) war ein britischer Astronom und Musiktheoretiker. Bosanquet war der Sohn eines Pfarrers, besuchte das Eton College und die Universität Oxford (Balliol College), wo er Bestnoten in Physik und Mathematik erhielt. Er schlug zwar anfangs die Juristenlaufbahn ein in Lincoln’s Inn in London, unterrichtete aber dann meist als Tutor (gelegentlich auch als Prüfer) für Naturwissenschaften in Oxford, wo er später Fellow des St. John’s College war. Später war er Professor am Royal College of Music. Ab 1890 ließ er sich aus Gesundheitsgründen in Teneriffa nieder und kehrte nur im Sommer nach England zurück.

| dbo:abstract | Robert Holford Macdowall Bosanquet (* 31. Juli 1841 in Rock Hall bei Alnwick, Northumberland; † 7. August 1912 in Castello Zamorra, Teneriffa) war ein britischer Astronom und Musiktheoretiker. Bosanquet war der Sohn eines Pfarrers, besuchte das Eton College und die Universität Oxford (Balliol College), wo er Bestnoten in Physik und Mathematik erhielt. Er schlug zwar anfangs die Juristenlaufbahn ein in Lincoln’s Inn in London, unterrichtete aber dann meist als Tutor (gelegentlich auch als Prüfer) für Naturwissenschaften in Oxford, wo er später Fellow des St. John’s College war. Später war er Professor am Royal College of Music. Ab 1890 ließ er sich aus Gesundheitsgründen in Teneriffa nieder und kehrte nur im Sommer nach England zurück. Er heiratete nie und starb in seinem Haus in Teneriffa. Er veröffentlichte zwischen 1875 und 1890 zahlreiche wissenschaftliche Artikel meist im Philosophical Magazine. Beispielsweise erfand er verallgemeinerte Klaviaturen für ungewöhnliche Tonsysteme und war eine anerkannte Autorität für Orgelbau. Zwei seiner speziell nach neuen Prinzipien entworfenen Heimorgeln überließ er dem South Kensington Museum, heute sind sie im Science Museum in South Kensington. Eines der Instrumente hat 48 Tasten pro Oktave (nach einem Tonsystem von Hermann von Helmholtz), das andere 84. Er befasste sich auch mit Elektrodynamik, wobei er theoretisch und experimentell arbeitete und ein neuartiges Polariskop erfand. In der Astronomie publizierte er zum Beispiel über Bahnbestimmung und babylonische Astronomie (in Zusammenarbeit mit Archibald Henry Sayce). 1871 wurde er Fellow der Royal Astronomical Society und 1890 der Royal Society. Er war der Bruder des Admirals Day Bosanquet und des Philosophen Bernard Bosanquet. (de) Robert Holford Macdowall Bosanquet FRS FRAS (31 July 1841 – 7 August 1912) was an English scientist and music theorist, and brother of Admiral Sir Day Bosanquet, and philosopher Bernard Bosanquet. Bosanquet was the son of Rev. R. W. Bosanquet of Rock Hall, Alnwick, Northumberland. He was educated at Eton College, and took first class honors in Natural Science and Mathematics at Balliol College, Oxford, and later became a fellow of St. John's College. He was called to the Bar at Lincoln's Inn, London but worked mainly tutoring at Oxford, notably for the Natural Science School, and later was Professor of Acoustics at the Royal College of Music. He was a musician and an authority on organ construction, and published a number of experimental and theoretical papers on acoustics, electromagnetism and astronomy. He was elected Fellow of the Royal Astronomical Society in 1871 and Fellow of the Royal Society in 1890. Bosanquet developed classes for musical tunings used mapping pitches in a coordinate arrangement he called a generalized keyboard, contrasting with Henry Ward Poole's and Colin Brown's keyboards which were based on symmetry of key relationships. The keyboard was demonstrated in two instruments loaned permanently to the South Kensington Museum in 1876: a 41⁄2-octave harmonium tuned in 53 equal temperament with 84 keys per octave built by T. A. Jennings in 1872–3, and a 3-octave generalized keyboard organ built in 1875 with 48 notes per octave tuned to Hermann von Helmholtz' approximate just intonation (schismatic temperament) or 36 notes per octave tuned in quarter-comma meantone selected by means of draw stops. In 1877, speculating on papers about Indian śrutis, he relaxed the arrangement to permit mapping 22 equal temperament. He also invented a sensitive polariscope working independent of direction. Well Temperament versus Equal Temperament: Marpurg is most likely at the source of a two-centuries misunderstanding that J. S. Bach would have been using the equal temperament for the performance of "Das Wohltemperirte Clavier", because of his publication "Versuch über die musikalische Temperatur", 1776,This misunderstanding was only much later first challenged by Robert Holford Bosanquet in "An Elementary Treatise on Musical Intervals and Temperament" 1876, pp. 29–30, but this position did not acquire fame.The above position of Bosanquet, that a distinction should be made between "well temperament" and "equal temperament" was rediscovered by H. Kelletat, and thoroughly defended and analysed historically in "Zur musikalischen Temperatur", 1960, especially p. 32. Thanks to this publication by H. Kelletat, almost all musicologists subscribe to this distinction nowadays. In 1890 he retired to Tenerife, spending summers in England. He died at his home called "El Castillo" (The Castle), near Los Realejos town, Tenerife Island (Canary Islands, Spain) in 1912. (en) |
