Richard Milburn, known as Whistling Dick, was an African-American musician in Philadelphia. He was a great guitarist and whistler and composed bird song themes including the tune Listen to the Mocking Bird which, when arranged with lyrics by Septimus Winner, became one of the most successful ballads of the 19th century, selling over twenty million copies of sheet music. Milburn made $5 for this while the finished work went on to make over $100,000.
