Clarence Leonidas "Leo" Fender (August 10, 1909 – March 21, 1991) was an American inventor who founded Fender Electric Instrument Manufacturing Company, or "Fender" for short. He left the company in the late 1960s, and later founded two other musical instrument companies, MusicMan and G&L Musical Instruments.

The guitars, bass guitars, and amplifiers he designed from the 1940s on are still relevant: the Fender Telecaster (1950) was the first mass-produced electric guitar; the Fender Stratocaster (1954) is among the world's most iconic electric guitars; the Fender Precision Bass (1951) set the standard for electric bass guitars; and the Fender Bassman amplifier, popular enough in its own right, became the basis for later amplifiers (notably by Marshall and Mesa Boogie) that dominated rock and roll music.

Clarence Leonidas Fender ("Leo") was born on August 10, 1909, to Clarence Monte Fender and Harriet Elvira Wood, owners of a successful orange grove located between Anaheim and Fullerton, California.

Yngwie Johann Malmsteen (/ˈɪŋveɪ ˈmɑːlmstiːn/ ING-vay MAHLM-steen; born Lars Johan Yngve Lannerbäck on 30 June 1963) is a Swedish guitarist, songwriter, multi-instrumentalist and bandleader. Malmsteen became known for his neo-classical playing style in heavy metal. Steve Huey of Allmusic stated that, "Yngwie Malmsteen is arguably the most technically accomplished hard rock guitarist to emerge during the '80s."

Malmsteen was born Lars Johan Yngve Lannerbäck in Stockholm, Sweden, as the second child of a musically-talented family. At age seven, he saw a television news report on the death of Jimi Hendrix, an event which had a profound impact on his musical path. Malmsteen, however, has stated that Hendrix had no musical impact on him, but on 18 September 1970 he saw a TV special of Hendrix, where he smashed and burned his guitar, and Malmsteen thought: "this is really cool". To quote his official website, "The day Jimi Hendrix died, the guitar-playing Yngwie was born".

At the age of 10 he took his mother's maiden name Malmsten as his surname, slightly changed it to Malmsteen, and Anglicised his third given name Yngve to "Yngwie". Malmsteen created his first band "Track On Earth" at the age of 10, consisting of himself and a friend from school on drums (Armin). Malmsteen was a teenager when he first encountered the music of the 19th century violinist composer Niccolò Paganini, whom he cites as his biggest classical music influence. Ritchie Blackmore and Uli Jon Roth are also cited as being significant influences, as is Brian May of Queen.
