Mikhail Mishaqa (1800- c.1889), historian and "founder" of the twenty-four equal quarter tone scale. Mishaqa was the first theorist to propose a division of the octave into roughly twenty-four equal intervals, this being the current basis of the Arab tone system; however, as his "Essay on the Art of Music for the Emir Shihab" makes clear, Mishaqa's teacher Sheikh Muhammad al-'Attar (1764-1828) was one of many people already familiar with the concept, although Mishaqa was the first to publish formal ideas on the topic. Mishaqa, born in Rashmayya, Lebanon, was also the first historian of modern Ottoman Syria and acted as US Honorary Consul in Damascus (appointed in 1859). Like most of those selected by foreign countries to represent them in Damascus, he was a Christian, his great-grandfather having converted to Catholicism.
