Problem: 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.

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?"

Problem: Peter Green (born Peter Allen Greenbaum, 29 October 1946) is a British blues rock guitarist. As the founder of Fleetwood Mac, he was inducted into the Rock and Roll Hall of Fame in 1998. Green's songs, such as "Albatross", "Black Magic Woman", "Oh Well", "The Green Manalishi (With the Two Prong Crown)" and "Man of the World", appeared on the record charts, and several have been adapted by a variety of musicians. Green was a major figure in the "second great epoch" of the British blues movement.

Green was eventually diagnosed with schizophrenia and spent time in psychiatric hospitals undergoing electroconvulsive therapy during the mid-1970s. Many sources attest to his lethargic, trancelike state during this period. In 1977, Green was arrested for threatening his accountant Clifford Davis with a shotgun. The exact circumstances are the subject of much speculation, the most famous being that Green wanted Davis to stop sending money to him. In the 2011 BBC documentary "Peter Green: Man of the World", Green stated that at the time he had just returned from Canada needing money and that, during a telephone conversation with his accounts manager, he alluded to the fact that he had brought back a gun from his travels. His accounts manager promptly called the police, who surrounded Green's house. In 1979, Green began to re-emerge professionally. With the help of his brother Michael, he was signed to Peter Vernon-Kell's PVK label, and produced a string of solo albums starting with 1979's In the Skies. He also made an uncredited appearance on Fleetwood Mac's double album Tusk, on the song "Brown Eyes", released the same year. In 1981, Green contributed to "Rattlesnake Shake" and "Super Brains" on Mick Fleetwood's solo album The Visitor. He recorded various sessions with a number of other musicians notably the Katmandu album A Case for the Blues with Ray Dorset of Mungo Jerry, Vincent Crane from The Crazy World of Arthur Brown and Len Surtees of The Nashville Teens. Despite attempts by Gibson Guitar Corporation to start talks about producing a "Peter Green signature Les Paul" guitar, Green's instrument of choice at this time was a Gibson Howard Roberts Fusion guitar. In 1986 Peter and his brother Micky contributed to the album A Touch of Sunburn by Lawrie 'The Raven' Gaines (under the group name 'The Enemy Within'). This album has been re-issued many times under such titles as "Post Modern Blues" and "Peter Green and Mick Green - Two Greens Make a Blues", often crediting Pirates guitarist Mick Green.
