Donald Thomas Scholz (born March 10, 1947) is an American rock musician, songwriter, inventor, engineer, and philanthropist. He is mainly known as the main songwriter, primary guitarist, founder and only remaining original member of the American rock band Boston. Scholz is an MIT-trained engineer who designed a recording studio in an apartment building's basement. A rock fan throughout his teen years, Scholz began writing songs while earning his master's degree at MIT. The first Boston album was mostly recorded in his basement studio, often using devices he designed and invented. After the success of Boston, he founded Scholz Research & Development, Inc. to develop and market his inventions, many under the Rockman brand. Scholz holds several patents related to his work at SR&D over the years. He was described by AllMusic as an "un-rock n' roll" figure who did not enjoy the limelight of being a performer, preferring to concentrate on music, production, and inventing new electronic equipment. In more recent years, he has dedicated much of his money and time to charitable work.
