Gross indecency is a UK and Canadian legal term of art which was used in the definition of the following criminal offences:

It also titles a play by Moisés Kaufman about Oscar Wilde's conviction of the former offence: Gross Indecency: The Three Trials of Oscar Wilde.

Oscar Fingal O'Flahertie Wills Wilde (16 October 1854 – 30 November 1900) was an Irish writer and poet. After writing in different forms throughout the 1880s, he became one of London's most popular playwrights in the early 1890s. Today he is remembered for his epigrams, plays and the circumstances of his imprisonment, followed by his early death.

Wilde's parents were successful Dublin intellectuals. Their son became fluent in French and German early in life. At university Wilde read Greats; he proved himself to be an outstanding classicist, first at Dublin, then at Oxford. He became known for his involvement in the rising philosophy of aestheticism, led by two of his tutors, Walter Pater and John Ruskin. After university, Wilde moved to London into fashionable cultural and social circles. As a spokesman for aestheticism, he tried his hand at various literary activities: he published a book of poems, lectured in the United States of America and Canada on the new "English Renaissance in Art", and then returned to London where he worked prolifically as a journalist. Known for his biting wit, flamboyant dress, and glittering conversation, Wilde had become one of the most well-known personalities of his day.

Alan Mathison Turing, OBE, FRS ( /ˈtjʊərɪŋ/ TEWR-ing; 23 June 1912 – 7 June 1954), was an English mathematician, logician, cryptanalyst, and computer scientist. He was highly influential in the development of computer science, providing a formalisation of the concepts of "algorithm" and "computation" with the Turing machine, which played a significant role in the creation of the modern computer. Turing is widely considered to be the father of computer science and artificial intelligence.

During the Second World War, Turing worked for the Government Code and Cypher School (GCCS) at Bletchley Park, Britain's codebreaking centre. For a time he was head of Hut 8, the section responsible for German naval cryptanalysis. He devised a number of techniques for breaking German ciphers, including the method of the bombe, an electromechanical machine that could find settings for the Enigma machine.

After the war he worked at the National Physical Laboratory, where he created one of the first designs for a stored-program computer, the ACE. In 1948 Turing joined Max Newman's Computing Laboratory at Manchester University, where he assisted in the development of the Manchester computers and became interested in mathematical biology. He wrote a paper on the chemical basis of morphogenesis, and he predicted oscillating chemical reactions such as the Belousov–Zhabotinsky reaction, which were first observed in the 1960s.
