 Passage 2:Leigh Lisker (December 7, 1918 – March 24, 2006) was an eminent American linguist and phonetician. Most of his career was spent at the University of Pennsylvania, where he was a professor and then emeritus professor of linguistics. Dr. Lisker received his A.B. in 1941, with a major in German, his M.A. in 1946, and a Ph.D. in 1949 in linguistics. He was a major figure in phonetics, working both at the University of Pennsylvania and at Haskins Laboratories in New Haven, CT, where he was a senior scientist from 1951 until the end of his life. He collaborated with several phoneticians, principally Arthur S. Abramson. He is best known for his work, done mostly in conjunction with Abramson, on voice onset time. Dr. Lisker also made important contributions to Dravidian linguistics, including the book Introduction to Spoken Telugu (Telugu), and did research comparing phonetic and phonological perceptions on the part of linguistically naive and linguistically sophisticated speakers of different native language backgrounds. He conducted such studies in collaboration with Dr. Abramson of the University of Connecticut, Bh. Krishnamurti  of University of Hyderabad, India, Adrian Fourcin  of University College London, and Mario Rossi  of the Institut de Phonétique at the Université de Provence, Aix-en-Provence.
 Passage 3:Beginning in 1974, Bryant began to state that he was receiving revelations from Jesus. He claimed that "John the Beloved" had visited him as an angel and instructed him to form an "Order of the Ancients". In 1975 he was taken in vision to the City of Enoch, where AUB founder Joseph White Musser and Latter Day Saint movement founder Joseph Smith ordained him to the presidency of the church and the high priesthood. At this time, Bryant claimed to be the "One Mighty and Strong" prophesied of in the Doctrine and Covenants. In 1975, he founded a church as the Church of Christ Patriarchal, which later was renamed the Evangelical Church of Christ. In 1979, Bryant's group established a communal settlement at the Fair Haven Ranch near Las Vegas, Nevada. During his time as a leader of the group, Bryant had six wives and taught his sect about drug experimentation and heterosexual and homosexual group sex. According to sources, sect members had sexual relations during the group's temple ceremonies. In 1981, the group lost the Fair Haven Ranch when they were unable to keep up on mortgage payments. As a result, Bryant, five of his six wives, and some of the members of the group relocated to Marion County, Oregon, near Salem.
