Question: What was the founder of the Material World Charitable Foundation often referred to as?

full_context: Document 1: John Barham: John Barham is an English classical pianist, composer, arranger, producer and educator. He is best known for his orchestration of George Harrison albums such as "All Things Must Pass" (1970) and for his association with Indian sitar maestro Ravi Shankar. Barham trained at the Royal College of Music and the School of Oriental and African Studies in London, before establishing himself during the mid 1960s as a composer of piano interpretations of Indian classical ragas. He became a student of Shankar, for whose East–West collaborations with Yehudi Menuhin and others he transcribed Indian melodies into Western musical annotation. Through Shankar, Barham began a long friendship with Harrison in 1966, then a member of the Beatles, which assisted Harrison's own education in Indian music as well as his promotion of the genre to Western audiences. Barham collaborated with Harrison on the latter's "Wonderwall Music" soundtrack album (1968), before providing the orchestral arrangements for "All Things Must Pass" songs such as "Isn't It a Pity" and "My Sweet Lord", and for Harrison's 1973 album "Living in the Material World".
Document 2: Living in the Material World: Living in the Material World is the fourth studio album by English musician George Harrison, released in 1973 on Apple Records. As the follow-up to 1970's critically acclaimed "All Things Must Pass" and his pioneering charity project, the Concert for Bangladesh, it was among the most highly anticipated releases of that year. The album was certified gold by the Recording Industry Association of America two days after release, on its way to becoming Harrison's second number 1 album in the United States, and produced the international hit "Give Me Love (Give Me Peace on Earth)". It also topped albums charts in Canada and Australia, and reached number 2 in Britain.
Document 3: George Harrison: George Harrison, {'1': ", '2': ", '3': ", '4': "} (25 February 1943 – 29 November 2001) was an English guitarist, singer-songwriter, and producer who achieved international fame as the lead guitarist of the Beatles. Often referred to as "the quiet Beatle", Harrison embraced Hinduism and helped broaden the horizons of his fellow bandmates as well as their American audience by incorporating Indian instrumentation in their music. Although most of the Beatles' songs were written by John Lennon and Paul McCartney, most Beatles albums from 1965 onwards contained at least two Harrison compositions. His songs for the group included "Taxman", "Within You Without You", "While My Guitar Gently Weeps", "Here Comes the Sun" and "Something", the last of which became the Beatles' second-most covered song.
Document 4: Material World Charitable Foundation: The Material World Charitable Foundation (MWF) is a charitable organisation founded by English musician George Harrison in April 1973. Its launch coincided with the release of Harrison's album "Living in the Material World" and came about in reaction to the taxation issues that had hindered his 1971–72 aid project for refugees of the Bangladesh Liberation War. Harrison assigned his publishing royalties from nine of the eleven songs on "Living in the Material World", including the hit single "Give Me Love (Give Me Peace on Earth)", to the foundation, in perpetuity.
Document 5: Something (Beatles song): "Something" is a song by the Beatles, written by George Harrison and released on the band's 1969 album "Abbey Road". It was also issued as a single coupled with another track from the album, "Come Together". "Something" was the first Harrison composition to appear as a Beatles A-side, and the only song written by him to top the US charts before the band's break-up in April 1970. The single was also one of the first Beatles singles to contain tracks already available on an LP album.
Document 6: Deep Blue (song): "Deep Blue" is a song by English musician George Harrison, released as the B-side to his 1971 charity single "Bangla Desh". Harrison wrote the song in 1970, midway through the recording sessions for "All Things Must Pass", and recorded it in Los Angeles the following year while organising the Concert for Bangladesh. The composition was inspired by the deteriorating condition of his mother, Louise, before she succumbed to cancer in July 1970, and by Harrison's feelings of helplessness as he visited her in hospital in the north of England. Given the subject matter of his lyrics, "Deep Blue" also served to convey the suffering endured by the millions of refugees from war-torn Bangladesh in 1971, as sickness and disease became widespread among their makeshift camps in northern India.
Document 7: Ravi Shankar's Music Festival from India: Ravi Shankar's Music Festival from India was an Indian classical music revue led by sitarist and composer Ravi Shankar intended for Western concert audiences and performed in 1974. Its presentation was the first project undertaken by the Material World Charitable Foundation, set up the previous year by ex-Beatle George Harrison. Long a champion of Indian music, Harrison also produced an eponymous studio album by the Music Festival orchestra, which was released in 1976 on his Dark Horse record label. Both the CD format of the Ravi Shankar's Music Festival from India album and a DVD of their performance at the Royal Albert Hall in London were issued for the first time on the 2010 Shankar–Harrison box set "Collaborations".
Document 8: Sue Me, Sue You Blues: "Sue Me, Sue You Blues" is a song written by English musician George Harrison, released on his 1973 album "Living in the Material World". Harrison initially let American guitarist Jesse Ed Davis record it for the latter's "Ululu" album (1972), in gratitude to Davis for his participation in the Concert for Bangladesh. When writing the song, Harrison drew inspiration from the legal issues surrounding the Beatles during the early months of 1971, particularly the lawsuit that Paul McCartney initiated in an effort to dissolve the band's business partnership, Apple Corps.
Document 9: Concert for George: The Concert for George was held at the Royal Albert Hall in London on 29 November 2002 as a memorial to George Harrison on the first anniversary of his death. The event was organised by Harrison's widow, Olivia, and son, Dhani, and arranged under the musical direction of Eric Clapton and Jeff Lynne. The profits from the event went to the Material World Charitable Foundation, an organisation set up by Harrison.
Document 10: George Martin: Sir George Henry Martin {'1': ", '2': ", '3': ", '4': "} (3 January 19268 March 2016) was an English record producer, arranger, composer, conductor, audio engineer, and musician. He was referred to as the "Fifth Beatle", including by Paul McCartney, in reference to his extensive involvement on each of the Beatles' original albums. Martin produced 30 number-one hit singles in the United Kingdom and 23 number-one hits in the United States.
Document 11: George Harrison (album): George Harrison is the eighth studio album by English musician George Harrison, released in February 1979. It was written and recorded through much of 1978, a period of domestic contentment for Harrison, during which he married Olivia Trinidad Arias and became a father for the first time, to son Dhani. Harrison wrote several of the songs in Hawaii, while the track "Faster" reflected his year away from music-making, when he and Arias attended many of the races in the 1977 Formula 1 World Championship. The album also includes the hit single "Blow Away" and "Not Guilty", a song that Harrison originally recorded in 1968 for the Beatles' White Album.
Document 12: The Lord Loves the One (That Loves the Lord): "The Lord Loves the One (That Loves the Lord)" is a song by English musician George Harrison, released on his 1973 album "Living in the Material World". Like the album's title track, it was inspired by the teachings of A.C. Bhaktivedanta Swami Prabhupada, founder of the International Society for Krishna Consciousness (ISKCON), more commonly known as the Hare Krishna movement. The song is an uptempo rock track with elements of blues and gospel. Some commentators have described it as the musical highpoint of "Living in the Material World", with Harrison's slide guitar playing singled out as being among the finest performances of his career.
Document 13: All Things Must Pass: All Things Must Pass is a triple album by English musician George Harrison. Recorded and released in 1970, the album was Harrison's first solo work since the break-up of the Beatles in April that year, and his third solo album overall. It includes the hit singles "My Sweet Lord" and "What Is Life", as well as songs such as "Isn't It a Pity" and the title track that had been turned down for inclusion on releases by the Beatles. The album reflects the influence of Harrison's musical activities with artists such as Bob Dylan, the Band, Delaney & Bonnie and Billy Preston during 1968–70, and his growth as an artist beyond his supporting role to former bandmates John Lennon and Paul McCartney. "All Things Must Pass" introduced Harrison's signature sound, the slide guitar, and the spiritual themes that would be present throughout his subsequent solo work. The original vinyl release consisted of two LPs of songs and a third disc of informal jams, titled "Apple Jam". Several commentators interpret Barry Feinstein's album cover photo, showing Harrison surrounded by four garden gnomes, as a statement on his independence from the Beatles.
Document 14: Within You Without You: "Within You Without You" is a song written by George Harrison and released on the Beatles' 1967 album "Sgt. Pepper's Lonely Hearts Club Band". It was Harrison's second composition in the Indian classical style, after "Love You To", and was inspired by his six-week stay in India with his mentor and sitar teacher, Ravi Shankar, over September–October 1966. Recorded in London without the other Beatles, the song features Indian instrumentation such as sitar, dilruba and tabla, and was performed by Harrison and members of the Asian Music Circle. The recording marked a significant departure from the Beatles' previous work; musically, it evokes the Indian devotional tradition, while the overtly spiritual quality of the lyrics reflects Harrison's absorption in Hindu philosophy and the teachings of the Vedas. Although the song was his only composition on "Sgt. Pepper", Harrison's endorsement of Indian culture was further reflected in the inclusion of yogis such as Paramahansa Yogananda among the crowd depicted on the album cover.
Document 15: Songs by George Harrison: Songs by George Harrison is a book of song lyrics and commentary by English musician George Harrison, with illustrations by New Zealand artist Keith West. It was published in February 1988, in a limited run of 2500 copies, by Genesis Publications, and included an EP of rare or previously unreleased Harrison recordings. Intended as a luxury item, each copy was hand-bound and boxed, and available only by direct order through Genesis in England. The book contains the lyrics to 60 Harrison compositions, the themes of which West represents visually with watercolour paintings. Starting in 1985, Harrison and West worked on the project for two years, during which Harrison returned to music-making with his album "Cloud Nine", after focusing on film production for much of the early 1980s. The book includes a foreword by his "Cloud Nine" co-producer, Jeff Lynne, and a written contribution from Elton John.
