Background: Rudolph Van Gelder (November 2, 1924 - August 25, 2016) was an American recording engineer who specialized in jazz. Regarded as the most important recording engineer of jazz by some observers, Van Gelder recorded several thousand jazz sessions, including many recognized as classics, in a career which spanned more than half a century. Van Gelder recorded many of the great names in the genre, including John Coltrane, Miles Davis, Thelonious Monk, Sonny Rollins, Art Blakey, Joe Henderson, Freddie Hubbard, Wayne Shorter, and Horace Silver, among many others. He worked with many record companies but was most closely associated with Blue Note Records.
Context: In 1967, Alfred Lion retired from running Blue Note, and the company's owners, Liberty Records (from 1965), began to use other engineers more regularly. Prestige, too, had started to use other studios a few years earlier. Van Gelder remained active in music recording, working as the engineer for most of Creed Taylor's CTI Records releases, a series of proto-smooth jazz albums that were financially successful, but not always well received by critics.  Though his output slowed, Van Gelder remained active as a recording engineer into the new century. In the late 1990s he worked as a recording engineer for some of the songs featured on the soundtrack to the TV Show Cowboy Bebop. From 1999, he remastered the analog Blue Note recordings he made several decades earlier into 24-bit digital recordings in its RVG Edition series and also a similar series of remasters of some of the Prestige albums he recorded for its current owners, Concord Records. He was positive about the switch from analog to digital technology. He told Audio magazine in 1995:  The biggest distorter is the LP itself. I've made thousands of LP masters. I used to make 17 a day, with two lathes going simultaneously, and I'm glad to see the LP go. As far as I'm concerned, good riddance. It was a constant battle to try to make that music sound the way it should. It was never any good. And if people don't like what they hear in digital, they should blame the engineer who did it. Blame the mastering house. Blame the mixing engineer. That's why some digital recordings sound terrible, and I'm not denying that they do, but don't blame the medium.  Van Gelder resided in Englewood Cliffs into this century. He died at his Engelwood Cliffs home on August 25, 2016.

Background: Dorothy Day, Obl.S.B. (November 8, 1897 - November 29, 1980) was an American journalist, social activist, and Catholic convert. Day initially lived a bohemian lifestyle before gaining fame as a social activist after her conversion. She later became a key figure in the Catholic Worker Movement and earned a national reputation as a political radical, perhaps the most famous radical in American Catholic Church history.
Context: Dorothy Day was born on November 8, 1897, in the Brooklyn Heights neighborhood of Brooklyn, New York. She was born into a family described by one biographer as "solid, patriotic, and middle class". Her father, John Day, was a Tennessee native of Irish heritage, while her mother, Grace Satterlee, a native of upstate New York, was of English ancestry. Her parents were married in an Episcopal church in Greenwich Village. She had three brothers and a sister. In 1904, her father, who was a sports writer devoted to horse racing, took a position with a newspaper in San Francisco. The family lived in Oakland, California, until the San Francisco Earthquake of 1906 destroyed the newspaper's facilities and her father lost his job. From the spontaneous response to the earthquake's devastation, the self-sacrifice of neighbors in a time of crisis, Day drew a lesson about individual action and Christian community. The family relocated to Chicago.  Day's parents were nominal Christians who rarely attended church. As a young child, she showed a marked religious streak, reading the Bible frequently. When she was ten she started to attend Church of Our Saviour, an Episcopal church in the Lincoln Park neighborhood of Chicago, after its rector convinced her mother to let Day's brothers join the church choir. She was taken with the liturgy and its music. She studied the catechism and was baptized and confirmed in that church in 1911.  Day was an avid reader in her teens, particularly fond of Upton Sinclair's The Jungle. She worked from one book to another, noting Jack London's mention of Herbert Spencer in Martin Eden, and then from Spencer to Darwin and Huxley. She learned about anarchy and extreme poverty from Peter Kropotkin, who promoted a belief in cooperation in contrast to Darwin's competition for survival. She also enjoyed Russian literature in university, especially Dostoevsky, Tolstoy, and Gorky. Day read a lot of socially conscious work, which gave her a background for her future; it helped bolster her support for and involvement in social activism.  In 1914, Day attended the University of Illinois at Urbana-Champaign on a scholarship. She was a reluctant scholar. Her reading was chiefly in a Christian radical social direction. She avoided campus social life and supported herself rather than rely on money from her father, buying all her clothing and shoes from discount stores. She left the university after two years and moved to New York City.
