IN: Charles Edward "Charlie" Haden (August 6, 1937 - July 11, 2014) was an American jazz double bass player, bandleader, composer and educator known for his deep, warm sound, and whose career spanned more than fifty years. In the late 1950s, Haden was an original member of the ground-breaking Ornette Coleman Quartet. Haden revolutionized the harmonic concept of bass playing in jazz. About him, German musicologist Joachim-Ernst Berendt commented, "His ability to create serendipitous harmonies by improvising melodic responses to Coleman's free-form solos (rather than sticking to predetermined harmonies) was both radical and mesmerizing.

Haden often said that he moved to Los Angeles in 1957 in search of pianist Hampton Hawes. He turned down a full scholarship at Oberlin College, which did not have an established jazz program at the time, to attend Westlake College of Music in Los Angeles. His first recordings were made that year with Paul Bley, with whom he worked until 1959. He also played with Art Pepper for four weeks in 1957, and from 1958 to 1959, with Hampton Hawes whom he met through his friendship with bassist Red Mitchell, For a time, he shared an apartment with the bassist Scott LaFaro. In May 1959, he recorded his first album with the Ornette Coleman Quartet, the seminal The Shape of Jazz to Come. Haden's folk-influenced style complemented Coleman's microtonal, Texas blues elements. Later that year, the Quartet moved to New York City and secured an extended booking at the avant-garde Five Spot Cafe. This residency lasted six weeks and represented the beginnings of their unique, free and avant-garde jazz. Ornette's quartet played everything by ear, as Haden explained: "At first when we were playing and improvising, we kind of followed the pattern of the song, sometimes. Then, when we got to New York, Ornette wasn't playing on the song patterns, like the bridge and the interlude and stuff like that. He would just play. And that's when I started just following him and playing the chord changes that he was playing: on-the-spot new chord structures made up according to how he felt at any given moment." In 1960, addiction to narcotics caused him to leave Coleman's band. He went to self-help rehabilitation in September 1963 at Synanon houses in Santa Monica, California and San Francisco, California. It was during the time he was at Synanon House that he met his first wife, Ellen David. They moved to New York City's Upper West Side where their four children were born: their son, Josh, in 1968, and in 1971, their triplet daughters Petra, Rachel and Tanya. They separated in 1975 and, subsequently, divorced.

IN: Andy Warhol (; born Andrew Warhola; August 6, 1928 - February 22, 1987) was an American artist, director and producer who was a leading figure in the visual art movement known as pop art. His works explore the relationship between artistic expression, celebrity culture, and advertising that flourished by the 1960s, and span a variety of media, including painting, silkscreening, photography, film, and sculpture. Some of his best known works include the silkscreen paintings Campbell's Soup Cans (1962) and Marilyn Diptych (1962), the experimental film Chelsea Girls (1966), and the multimedia events known as the Exploding Plastic Inevitable (1966-67). Born and raised in Pittsburgh, Warhol initially pursued a successful career as a commercial illustrator.

Warhol died in Manhattan at 6:32 a.m. on February 22, 1987 at age 58. According to news reports, he had been making a good recovery from gallbladder surgery at New York Hospital before dying in his sleep from a sudden post-operative irregular heartbeat. Prior to his diagnosis and operation, Warhol delayed having his recurring gallbladder problems checked, as he was afraid to enter hospitals and see doctors. His family sued the hospital for inadequate care, saying that the arrhythmia was caused by improper care and water intoxication. The malpractice case was quickly settled out of court; Warhol's family received an undisclosed sum of money. Shortly before Warhol's death, doctors expected Warhol to survive the surgery, though a revaluation of the case about thirty years after his death showed many indications that Warhol's surgery was in fact riskier than originally thought. It was widely reported at the time that Warhol died of a "routine" surgery, though when considering factors such as his age, a family history of gallbladder problems, his previous gunshot wounds, and his medical state in the weeks leading up to the procedure, the potential risk of death following the surgery appeared to have been significant. Warhol's brothers took his body back to Pittsburgh, where an open-coffin wake was held at the Thomas P. Kunsak Funeral Home. The solid bronze casket had gold-plated rails and white upholstery. Warhol was dressed in a black cashmere suit, a paisley tie, a platinum wig, and sunglasses. He was laid out holding a small prayer book and a red rose. The funeral liturgy was held at the Holy Ghost Byzantine Catholic Church on Pittsburgh's North Side. The eulogy was given by Monsignor Peter Tay. Yoko Ono and John Richardson were speakers. The coffin was covered with white roses and asparagus ferns. After the liturgy, the coffin was driven to St. John the Baptist Byzantine Catholic Cemetery in Bethel Park, a south suburb of Pittsburgh. At the grave, the priest said a brief prayer and sprinkled holy water on the casket. Before the coffin was lowered, Paige Powell dropped a copy of Interview magazine, an Interview T-shirt, and a bottle of the Estee Lauder perfume "Beautiful" into the grave. Warhol was buried next to his mother and father. A memorial service was held in Manhattan for Warhol on April 1, 1987, at St. Patrick's Cathedral, New York.
