Some context: The Beatles were an English rock band formed in Liverpool in 1960. With members John Lennon, Paul McCartney, George Harrison and Ringo Starr, they became widely regarded as the foremost and most influential music band. Rooted in skiffle, beat and 1950s rock and roll, the Beatles later experimented with several musical styles, ranging from pop ballads and Indian music to psychedelia and hard rock, often incorporating classical elements and unconventional recording techniques in innovative ways. In 1963 their enormous popularity first emerged as "Beatlemania"; as the group's music grew in sophistication, led by primary songwriters Lennon and McCartney, the band were integral to pop music's evolution into an art form and to the development of the counterculture of the 1960s.
In Icons of Rock: An Encyclopedia of the Legends Who Changed Music Forever, Scott Schinder and Andy Schwartz describe the Beatles' musical evolution: In their initial incarnation as cheerful, wisecracking moptops, the Fab Four revolutionised the sound, style, and attitude of popular music and opened rock and roll's doors to a tidal wave of British rock acts. Their initial impact would have been enough to establish the Beatles as one of their era's most influential cultural forces, but they didn't stop there. Although their initial style was a highly original, irresistibly catchy synthesis of early American rock and roll and R&B, the Beatles spent the rest of the 1960s expanding rock's stylistic frontiers, consistently staking out new musical territory on each release. The band's increasingly sophisticated experimentation encompassed a variety of genres, including folk-rock, country, psychedelia, and baroque pop, without sacrificing the effortless mass appeal of their early work. In The Beatles as Musicians, Walter Everett describes Lennon and McCartney's contrasting motivations and approaches to composition: "McCartney may be said to have constantly developed - as a means to entertain - a focused musical talent with an ear for counterpoint and other aspects of craft in the demonstration of a universally agreed-upon common language that he did much to enrich. Conversely, Lennon's mature music is best appreciated as the daring product of a largely unconscious, searching but undisciplined artistic sensibility." Ian MacDonald describes McCartney as "a natural melodist - a creator of tunes capable of existing apart from their harmony". His melody lines are characterised as primarily "vertical", employing wide, consonant intervals which express his "extrovert energy and optimism". Conversely, Lennon's "sedentary, ironic personality" is reflected in a "horizontal" approach featuring minimal, dissonant intervals and repetitive melodies which rely on their harmonic accompaniment for interest: "Basically a realist, he instinctively kept his melodies close to the rhythms and cadences of speech, colouring his lyrics with bluesy tone and harmony rather than creating tunes that made striking shapes of their own." MacDonald praises Harrison's lead guitar work for the role his "characterful lines and textural colourings" play in supporting Lennon and McCartney's parts, and describes Starr as "the father of modern pop/rock drumming".

Some context: Hedy Lamarr (; born Hedwig Eva Maria Kiesler, November 9, 1914 - January 19, 2000) was an Austrian-born American film actress and inventor. At the beginning of World War II, Lamarr and composer George Antheil developed a radio guidance system for Allied torpedoes, which used spread spectrum and frequency hopping technology to defeat the threat of jamming by the Axis powers. Although the US Navy did not adopt the technology until the 1960s, the principles of their work are arguably incorporated into Bluetooth technology, and are similar to methods used in legacy versions of CDMA and Wi-Fi.
Lamarr was born Hedwig Eva Maria Kiesler in 1914 in Vienna, Austria-Hungary, the only child of Gertrud "Trude" Kiesler (nee Lichtwitz; 1894-1977) and Emil Kiesler (1880-1935). Her father was born to a Jewish family in Lemberg (now Lviv in Ukraine) and was a successful bank director. Her mother Gertrud was a pianist and Budapest native who came from an upper-class Jewish family; she had converted from Judaism to Catholicism and was described as a "practicing Christian", who raised her daughter as a Christian. Lamarr helped get her mother out of Austria (then under Nazi domination) and to the United States, and she later became an American citizen. Gertrud Kiesler put "Hebrew" as her race on her petition for naturalization as an American citizen. In the late 1920s, Lamarr was discovered as an actress and brought to Berlin by producer Max Reinhardt. Following her training in the theater, she returned to Vienna to work in the film industry, first as a script girl, and soon as an actress. In early 1933, at age 18, she starred in Gustav Machaty's film, Ecstasy (Ekstase in German, Extase in Czech). Her role was that of a neglected young wife married to an indifferent older man. The film became both celebrated and notorious for showing Lamarr's face in the throes of orgasm as well as close-up and brief nude scenes, a result of her being "duped" by the director and producer, who used high-power telephoto lenses. Although she was dismayed and now disillusioned about taking other roles, the film gained world recognition after winning an award in Rome. Throughout Europe, the film was considered an artistic work, while in America, it was considered overly sexual and received negative publicity, especially among women's groups. It was banned there and in Germany. She went on to play a number of stage roles, including a starring one in Sissy, a play about Austrian royalty produced in Vienna, which won accolades from critics. Admirers sent roses to her dressing room and tried to get backstage to meet her. She sent most of them away, including a man who was more insistent, Friedrich Mandl. He became obsessed with getting to know her. She fell for his charming and fascinating personality, partly due to his immense financial status. Her parents, both of Jewish descent, did not approve, due to Mandl's ties to Mussolini, and later, Hitler, but could not stop the headstrong Hedy.
