Background: Tatchell was born in Melbourne, Australia. His father was a lathe operator and his mother worked in a biscuit factory. His parents divorced when he was four and his mother remarried soon afterwards. Since the family finances were strained by medical bills, he had to leave school at 16 in 1968.
Context: To avoid conscription into the Australian Army, Tatchell moved to London in 1971. He had accepted being gay in 1969, and in London became a leading member of the Gay Liberation Front (GLF) until its 1974 collapse. During this time Tatchell was prominent in organising sit-ins at pubs that refused to serve "poofs" and protests against police harassment and the medical classification of homosexuality as an illness. With others he helped organise Britain's first Gay Pride march in 1972.  In 1973, he attended the 10th World Youth Festival in East Berlin on GLF's behalf. His actions triggered opposition within and between different groups of national delegates including the Communist Party of Great Britain and National Union of Students. He was banned from conferences, had his leaflets confiscated and burned, was interrogated by the secret police (the Stasi) and threatened and assaulted by other delegates, mostly communists.  Tatchell later claimed that this was the first time gay liberation politics were publicly disseminated and discussed in a communist country, although he noted that, in terms of decriminalisation and the age of consent, gay men had greater rights in East Germany at the time than in Britain and much of the West.  Describing his time in the Gay Liberation Front, he wrote in The Guardian that:  [The] GLF was a glorious, enthusiastic and often chaotic mix of anarchists, hippies, leftwingers, feminists, liberals and counter-culturalists. Despite our differences, we shared a radical idealism - a dream of what the world could and should be - free from not just homophobia but the whole sex-shame culture, which oppressed straights as much as LGBTs. We were sexual liberationists and social revolutionaries, out to turn the world upside down. [...] GLF's main aim was never equality within the status quo. [...] GLF's strategy for queer emancipation was to change society's values and norms, rather than adapt to them. We sought a cultural revolution to overturn centuries of male heterosexual domination and thereby free both queers and women. [...] Forty years on, GLF's gender agenda has been partly won. [...] Girlish boys and boyish girls don't get victimised as much as in times past. LGBT kids often now come out at the age of 12 or 14. While many are bullied, many others are not. The acceptance of sexual and gender diversity is increasing.

Problem: Background: Tierney was born on November 19, 1920 in Brooklyn, New York, the daughter of Howard Sherwood Tierney and Belle Lavinia Taylor. She was named after a beloved uncle, who died young. She had an elder brother, Howard Sherwood "Butch" Tierney, Jr., and a younger sister, Patricia "Pat" Tierney. Their father was a successful insurance broker of Irish descent, their mother a former physical education instructor.
Context: In Tierney's first role on Broadway, she carried a bucket of water across the stage in What a Life! (1938). A Variety magazine critic declared, "Miss Tierney is certainly the most beautiful water carrier I've ever seen!" She also worked as an understudy in The Primrose Path (1938).  The following year, she appeared in the role of Molly O'Day in the Broadway production Mrs. O'Brien Entertains (1939). The New York Times critic Brooks Atkinson wrote, "As an Irish maiden fresh from the old country, Gene Tierney in her first stage performance is very pretty and refreshingly modest." That same year, Tierney appeared as Peggy Carr in Ring Two (1939) to favorable reviews. Theater critic Richard Watts, Jr. of the New York Herald Tribune wrote, "I see no reason why Miss Tierney should not have an interesting theatrical career - that is, if cinema does not kidnap her away."  Tierney's father set up a corporation, Belle-Tier, to fund and promote her acting career. Columbia Pictures signed her to a six-month contract in 1939. She met Howard Hughes, who tried unsuccessfully to seduce her. From a well-to-do family herself, she was not impressed by his wealth. Hughes eventually became a lifelong friend.  After a cameraman advised Tierney to lose a little weight, she wrote to Harper's Bazaar magazine for a diet, which she followed for the next 25 years. Tierney was initially offered the lead role in National Velvet, but production was delayed. When Columbia Pictures failed to find Tierney a project, she returned to Broadway and starred as Patricia Stanley to critical and commercial success in The Male Animal (1940). In The New York Times, Brooks Atkinson wrote, "Tierney blazes with animation in the best performance she has yet given". She was the toast of Broadway before her 20th birthday. The Male Animal was a hit, and Tierney was featured in Life magazine. She was also photographed by Harper's Bazaar, Vogue, and Collier's Weekly.  Two weeks after The Male Animal opened, Darryl F. Zanuck, the head of 20th Century Fox, was rumored to have been in the audience. During the performance, he told an assistant to note Tierney's name. Later that night, Zanuck dropped by the Stork Club, where he saw a young lady on the dance floor. He told his assistant, "Forget the girl from the play. See if you can sign that one." It was Tierney. At first, Zanuck did not think she was the actress he had seen. Tierney was quoted (after the fact), saying: "I always had several different 'looks', a quality that proved useful in my career."
