Background: Morello was born on May 30, 1964, in Harlem, New York, to Ngethe Njoroge and Mary Morello. Morello, an only child, is the son of an American mother of Italian and Irish descent and a Kikuyu Kenyan father. His mother was a schoolteacher from Marseilles, Illinois, who earned a Master of Arts at Loyola University, Chicago and traveled to Germany, Spain, Japan, and Kenya as an English language teacher between 1977 and 1983. His father participated in the Mau Mau Uprising and was Kenya's first ambassador to the United Nations.
Context: Morello and Serj Tankian of System of a Down are the co-founders of Axis of Justice, a political group whose declared purpose is "to bring together musicians, fans of music, and grassroots political organizations to fight for social justice together." They "aim to build a bridge between fans of music around the world and local political organizations to effectively organize around issues of peace, human rights, and economic justice." The group has worked for such causes as immigrant rights and death-penalty abolition. Its recommended book list includes such authors as Karl Marx, Che Guevara, George Orwell, Noam Chomsky, Mumia Abu-Jamal and Grant Morrison.  Morello and Tankian, together with a handful of other artists, including Maynard James Keenan, Wayne Kramer of the MC5, the hip hop group Jurassic 5, and Michael "Flea" Balzary of the Red Hot Chili Peppers, released a live recording of covers and original songs, titled The Axis of Justice Concert Series Volume 1.  On April 6, 2006, Morello was honored with the Eleanor Roosevelt Human Rights Award for his support of worker's rights and for his AOJ work. Morello has worked on numerous labor campaigns: the Guess sweatshop boycott, the LA janitors strike, the Taco Bell boycott, the southern California grocery workers strike and lockout, and others.  Morello was a strong supporter of the 2006 United States immigration reform protests around the US. He feels that there's enough room for everyone in the United States. Morello played as the Nightwatchman at MacArthur Park in Los Angeles and has featured many articles on AOJ. On September 28, 2006, Morello was one of 400 protesters arrested protesting in support of immigrant hotel workers' rights, in what organizers called "the largest act of civil disobedience in the history of Los Angeles". Morello knew he was going to be arrested; he wore bright yellow signs, and gave the LAPD his driver's license number a few days before the march. Morello told MTV:  "In these political dark ages, it's important for us to stand up for one another. These hotel workers by the airport make 20% less wages than the hotel workers around the rest of Los Angeles. We are here to express our solidarity with them, to help them unionize and help them close the gap between their sub-poverty wages and the millions and millions of dollars the people who own these hotels make."

Background: Cullen was born in Hamilton, Lanarkshire. His father William was a lawyer retained by the Duke of Hamilton as factor, and his mother was Elizabeth Roberton of Whistlebury. He studied at the Old Grammar School of Hamilton (renamed in 1848 The Hamilton Academy), then, in 1726, began a General Studies arts course at the University of Glasgow. He began his medical training as apprentice to John Paisley, a Glasgow apothecary surgeon, then spent 1729 as surgeon on a merchant vessel trading between London and the West Indies.
Context: In 1755 he was enticed by Lord Kames to become Professor of Chemistry and Medicine at the University of Edinburgh. It was in Edinburgh, in 1756, that he gave the first documented public demonstration of artificial refrigeration. Cullen used a pump to create a partial vacuum over a container of diethyl ether, which then boiled, absorbing heat from the surroundings. This created a small amount of ice, but the process found no commercial application.  From 1757 he delivered lectures on clinical medicine in the Edinburgh Royal Infirmary. On the death of Charles Alston in 1760, Cullen at the request of the students undertook to finish his course of lectures on materia medica; he delivered an entirely new course, notes of which were published in an unauthorised edition in 1771, but which he re-wrote and issued as A Treatise on Materia Medica in 1789.  On the death of Robert Whytt, the professor of the institutes of medicine, Cullen accepted the chair, at the same time resigning that of chemistry. In the same year he had been an unsuccessful candidate for the professorship of the practice of physic (medicine), but subsequently an arrangement was made between him and John Gregory, the successful candidate, by which they both agreed to deliver alternate courses on the theory and practice of medicine. This arrangement continued until the sudden death of Gregory in 1773. Cullen was then appointed sole professor of the practice of physic, and he continued in this office until a few months before his death.  In 1783 Cullen (together with his sons) was a co-founder of the Royal Society of Edinburgh.  He died on 5 February 1790 in Kirknewton, West Lothian, and is buried in the churchyard there. His son Robert lies with him.
