Brian May ($175 million)
This singer, multi-instrumentalist, electrical engineer, and doctor of astrophysics held down the left side of the stage for Queen from beginning to end. May even built his own guitar, which he calls “The Red Special,” in a way that mimicked the active pickups of a Fender Telecaster, the body of a Stratocaster, and the action of a Gibson SG, which were the most popular guitars on the market in the early 1960s when Queen was formed. Due to his actions in the physics world, and his involvement with Queen, Brian may is roughly worth $175 million.
