On this day in 2016, we lost "The Fifth Beatle," Sir George Henry Martin. The English record producer, arranger, composer, conductor, audio engineer, and musician produced 30 number-one hit singles in the UK and 23 number-one hits in the US. His career spanned more than six decades of work in music, film, television, and live performance. Prior to The Beatles, Martin produced comedy and novelty records in the early 1950s, working with Peter Sellers, Spike Milligan, and Bernard Cribbins, among others. In recognition of his services to the music industry and popular culture, he was made a Knight Bachelor in 1996. To truly understand his greatness, and how he was instrumental in The Beatles' sound (and ultimate success) watch this video profile below.
