Robert Campbell began his career in the music industry working for Conn Organ in 1947, the year the company gave a unit to President Harry S. Truman. Bob later worked with Don Leslie, the inventor of the famed Leslie organ speaker. Bob played an important role in the Leslie Speaker Company being purchased by the musical instrument division of CBS. Don and Bob made a dynamic duo in the promotion and marketing of the speaker products; they had several obstacles to overcome and yet still wound up on top. He stayed on with the Leslie product under CBS for five years before he was promoted to President of CBS Musical Instruments. He retired from CBS in the early 1980s to Bloomington, IN.
