Frank Anthony "Tony" Iommi (born 19 February 1948, in Birmingham, England) is an English guitarist and songwriter. He is most famous for starting the heavy metal band Black Sabbath. He is the only person who has stayed a member of the band since it began in 1968. He lost two finger tips in a work accident, and made two fake finger tips from a plastic bottle. This helped give Black Sabbath their heavy sound.
