day, the women's singles tournament opened, and Billie Jean King of the United States (listed locally as "Mrs. L. W. King") defeated Scotland's Winnie Shaw in straight sets, 6–2, 8–6. Died: Georges Lemaître, 71, Belgian Catholic priest and astrophysicist who, in 1927, first proposed the idea of the "Big Bang" theory of the creation of universe. June 21, 1966 (Tuesday) Arthur Calwell, the Leader of the Opposition in the Australian House of Representatives, and the leader of the Australian Labor Party, was wounded in an assassination attempt after he finished a speech at an anti-conscription rally at the Mosman Town Hall in Sydney, Australia. A 19-year-old student, Peter Kocan, approached the passenger side of Calwell's vehicle and fired a sawed-off shotgun at Calwell at point-blank range. The closed window deflected the bullet, which lodged harmlessly in Calwell's coat lapel. Calwell himself was only slightly injured, with minor facial lacerations from broken glass. As an author noted later, Calwell had started to roll down his window when he saw Kocan, whom he assumed to be a supporter, running towards his car and, "Had his window been fully down, Calwell would have been killed; only the glass barrier had saved him." "Washoe", a nine-month old female chimpanzee from West Africa, arrived at the home of Beatrix T. Gardner and R. Allen Gardner, two psychology professors at the University of Nevada, Reno. Taught by the Gardners, Washoe would become the first non-human to learn to communicate with humans, learning 350 symbols in American Sign Language. The film adaptation of Who's Afraid of Virginia Woolf? premiered at the Pantages Theatre in Hollywood, California, days after Jack Valenti of the Motion Picture Association of America (MPAA) gave its approval in spite of the strictures of the MPAA's Production Code, a prerequisite for being shown in most American cinemas. The Mike Nichols film could be distributed as long as the theater operator signed a rider to a standard contract "prohibiting anyone under the age of 18 from seeing the picture unless accompanied by an adult", a forerunner to the "R" Rating that would be implemented as part of the limitations system that would be created on November 5, 1968. The MPAA released a statement at the time noting that "this exemption does not mean that the floodgates are open for language or other material" judged to be obscene.
