The Incredible String Band (sometimes abbreviated as ISB) were a psychedelic folk band formed by Clive Palmer, Robin Williamson and Mike Heron in Scotland in 1966. The band built a considerable following, especially in the British counterculture, notably with their albums The 5000 Spirits or the Layers of the Onion, The Hangman's Beautiful Daughter, and Wee Tam and the Big Huge. They became pioneers in psychedelic folk and, through integrating a wide variety of traditional music forms and instruments, in the development of world music. Following Palmer's early departure, Williamson and Heron performed as a duo, later augmented by other musicians.
After that the group lasted another four years, although there was a gradual decline in their status and commercial success after 1970. Joe Boyd, whose skillful handling of the band had contributed much to their international success, stopped managing them and returned to the US. The group left Elektra Records and signed with Island, for whom they recorded five albums. The first was a soundtrack to the "Be Glad..." film, and this was followed by the eclectic Liquid Acrobat as Regards the Air, regarded as their best album for some time. The band continued to tour and record. Rose Simpson left in 1971 and was replaced by Malcolm Le Maistre, formerly of the Stone Monkey troupe. Mike Heron took time out to record a well-received solo album, Smiling Men with Bad Reputations, which, in contrast to the ISB's self-contained productions, featured a host of session guests, among them Pete Townshend, Ronnie Lane, Keith Moon, John Cale and Richard Thompson. The following year, Licorice left, and was replaced by Gerard Dott, an Edinburgh jazz musician and friend of both Heron and Williamson who had contributed to Smiling Men. Williamson also recorded a solo album, Myrrh, which featured some of his most extraordinary vocal performances. The group's changing lineup, adding Stan Schnier (aka "Stan Lee") on bass, Jack Ingram on drums, and Graham Forbes on electric guitar reflected moves toward a more conventional amplified rock group. Their final albums for Island were received disappointingly, and the label dropped them in 1974. By then, disagreements between Williamson and Heron about musical policy had become irreconcilable, and they split up in October 1974.

Edward Sapir (; January 26, 1884 - February 4, 1939) was an American anthropologist-linguist, who is widely considered to be one of the most important figures in the early development of the discipline of linguistics. Sapir was born in German Pomerania; his parents emigrated to United States of America when he was a child. He studied Germanic linguistics at Columbia, where he came under the influence of Franz Boas who inspired him to work on Native American languages.
From 1931 until his death in 1939, Sapir taught at Yale University, where he became the head of the Department of Anthropology. He was invited to Yale to found an interdisciplinary program combining anthropology, linguistics and psychology, aimed at studying "the impact of culture on personality". While Sapir was explicitly given the task of founding a distinct anthropology department, this was not well received by the department of sociology who worked by William Graham Sumner's "Evolutionary sociology", which was anathema to Sapir's Boasian approach, nor by the two anthropologists of the Institute for Human Relations Clark Wissler and G. P. Murdock. Sapir never thrived at Yale, where as one of only four Jewish faculty members out of 569 he was denied membership to the faculty club where the senior faculty discussed academic business. At Yale, Sapir's graduate students included Morris Swadesh, Benjamin Lee Whorf, Mary Haas, Charles Hockett, and Harry Hoijer, several of whom he brought with him from Chicago. Sapir came to regard a young Semiticist named Zellig Harris as his intellectual heir, although Harris was never a formal student of Sapir. (For a time he dated Sapir's daughter.) In 1936 Sapir clashed with the Institute for Human Relations over the research proposal by anthropologist Hortense Powdermaker, who proposed a study of the black community of Indianola, Mississippi. Sapir argued that her research should be funded instead of the more sociological work of John Dollard. Sapir eventually lost the discussion and Powdermaker had to leave Yale. In the summer of 1937 while teaching at the Linguistic Institute of the Linguistic Society of America in Ann Arbor, Sapir began having problems with a heart condition that had initially been diagnosed a couple of years earlier. In 1938, he had to take a leave from Yale, during which Benjamin Lee Whorf taught his courses and G. P. Murdock advised some of his students. After Sapir's death in 1939, G. P. Murdock became the chair of the anthropology department. Murdock, who despised the Boasian paradigm of cultural anthropology, dismantled most of Sapir's efforts to integrate anthropology, psychology, and linguistics.

Did he work on any other projects during this time?
