Problem: Background: Henry Havelock Ellis, known as Havelock Ellis (2 February 1859 - 8 July 1939), was an English physician, writer, progressive intellectual and social reformer who studied human sexuality. He co-authored the first medical textbook in English on homosexuality in 1897, and also published works on a variety of sexual practices and inclinations, as well as on transgender psychology. He is credited with introducing the notions of narcissism and autoeroticism, later adopted by psychoanalysis. Ellis was among the pioneering investigators of psychedelic drugs and the author of one of the first written reports to the public about an experience with mescaline, which he conducted on himself in 1896.
Context: Ellis was strongly opposed to the idea of castration for eugenic purposes. In 1909, regulations were introduced at the Cantonal Asylum in Bern, which allowed those deemed 'unfit' and with strong sexual inclinations to be mandatorily sterilized. In a particular instance, several men and women, including epileptics and pedophiles were castrated, some of whom voluntarily requested it. While the results were positive, in that none of the subjects were found guilty of any more sexual offences, Ellis remained staunchly opposed to the practice. His view on the origin of these inclinations was that sexual impulses do not reside in the sexual organs, but rather they persist in the brain. Moreover, he posited that the sexual glands provided an important source of internal secretions vital for the functioning of the organism, and thus their removal could greatly injure the patient.  However, already in his time, Ellis was witness to the rise of vasectomies and ligatures of the Fallopian tubes, which performed the same sterilization without removing the whole organ. In these cases, Ellis was much more favorable, yet still maintaining that "sterilization of the unfit, if it is to be a practical and humane measure commanding general approval, must be voluntary on the part of the person undergoing it, and never compulsory." His opposition to such a system was not only rooted in morality. Rather, Ellis also considered the practicality of the situation, hypothesizing that if an already mentally unfit man is forced to undergo sterilization, he would only become more ill-balanced, and would end up committing more anti-social acts.  Though Ellis was never at ease with the idea of forced sterilizations, he was willing to find ways to circumvent that restriction. His focus was on the social ends of eugenics, and as a means to it, Ellis was in no way against 'persuading' 'volunteers' to undergo sterilization by withdrawing Poor Relief from them. While he preferred to convince those he deemed unfit using education, Ellis supported coercion as a tool. Furthermore, he supported adding ideas about eugenics and birth control to the education system in order to restructure society, and to promote social hygiene. For Ellis, sterilization seemed to be the only eugenic instrument that could be used on the mentally unfit. In fact, in his publication The Sterilization of the Unfit, Ellis argued that even institutionalization could not guarantee the complete prevention of procreation between the unfit, and thus, "the burdens of society, to say nothing of the race, are being multiplied. It is not possible to view sterilization with enthusiasm when applied to any class of people...but what, I ask myself, is the practical alternative?"
Question: did his theories influence anything?
Answer: Furthermore, he supported adding ideas about eugenics and birth control to the education system in order to restructure society, and to promote social hygiene.

Problem: Background: DeVito was born in Neptune Township, New Jersey, the son of Daniel DeVito, Sr., a small business owner, and Julia DeVito (nee Moccello). He grew up in a family of five, with his parents and two older sisters. He is of Italian descent; his family is originally from San Fele, Basilicata. He was raised in Asbury Park, New Jersey.
Context: DeVito played Martini in the 1975 film One Flew Over the Cuckoo's Nest, reprising his role from the 1971 off-Broadway play of the same title. He gained fame in 1978 playing Louie De Palma, the short but domineering dispatcher for the fictional Sunshine Cab Company, on the hit TV show Taxi. After Taxi ended, DeVito began a successful film career, starting with roles in 1983's Terms of Endearment, as the comic rogue in the romantic adventure Romancing the Stone, starring Michael Douglas and Kathleen Turner, and its 1985 sequel, The Jewel of the Nile. In 1986, DeVito starred in Ruthless People with Bette Midler and Judge Reinhold, and in 1987, he made his feature-directing debut with the dark comedy Throw Momma from the Train, in which he starred with Billy Crystal and Anne Ramsey. Two years later, DeVito reunited with Douglas and Turner in The War of the Roses, which he directed and in which he co-starred.  DeVito's work during this time includes Other People's Money with Gregory Peck, director Barry Levinson's Tin Men as a competitive rival salesman to Richard Dreyfuss' character, two co-starring vehicles with Arnold Schwarzenegger (the comedies Twins and Junior), and playing The Penguin as a deformed sociopath in director Tim Burton's Batman Returns (1992) as well in the 1996 film adaptation Matilda in which he played the villainous car dealer and Matilda's father Harry Wormwood.  Although generally a comic actor, DeVito expanded into dramatic roles with The Rainmaker (1997), Hoffa (1992), which he directed and in which he co-starred with Jack Nicholson, Jack the Bear (1993), L.A. Confidential, The Big Kahuna, and Heist (2001), as a gangster nemesis of Joe Moore (Gene Hackman).  DeVito has an interest in documentaries: In 2006, he began a partnership with Morgan Freeman's company ClickStar, on which he hosts a documentary channel called Jersey Docs. He was also interviewed in the documentary Revenge of the Electric Car, about his interest in and ownership of electric vehicles.
