King Tubby (January 28, 1941 – February 6, 1989) was a Jamaican electronics and sound engineer, known primarily for his influence on the development of dub in the 1960s and 1970s. Born Osbourne Ruddock, Tubby's innovative studio work, which saw him elevate the role of the mixing engineer to a creative fame previously only reserved for composers and musicians, would prove to be influential across many genres of popular music. He is often cited as the inventor of the concept of the remix, and so may be seen as a direct antecedent of much dance and electronic music production.

Mikey Dread stated "King Tubby truly understood sound in a scientific sense. He knew how the circuits worked and what the electrons did. That's why he could do what he did".

King Tubby's music career began in the 1950s with the rising popularity of Jamaican sound systems, which were to be found all over Kingston and which were developing into enterprising businesses. As a talented radio repairman, Tubby soon found himself in great demand by most of the major sound systems of Kingston, as the tropical weather of the Caribbean island, (often combined with sabotage by rival sound system owners) led to malfunctions and equipment failure. Tubby owned an electrical repair shop on Drumalie Avenue, Kingston, that fixed televisions and radios. It was here that he built large amplifiers for the local sound systems. In 1961/62 he built his own radio transmitter and briefly ran a pirate radio station playing ska and rhythm and blues which he soon shut down when he heard that the police were looking for the perpetrators. Tubby would eventually form his own sound system, Tubby's Hometown Hi-Fi, which became a crowd favourite due to the high quality sound of his equipment, exclusive releases and Tubby's own echo and reverb sound effects, at that point something of a novelty.
