Dolby, nee Thomas Robertson, the son of a Trinity College classics professor, was the youngest of 6 children and the only one not to continue higher learning beyond secondary school. Despite a lack of classical music training, he soon became an in-demand keyboardist and a solo artist, probably best known for She Blinded Me With Science. Disenfranchised with the music industry, he founded a Silicon Valley startup that pioneered audio on the internet and eventually mobile phones, including the tune behind the Nokia Waltz.

The Speed of Sound is a well-written and insightful book on a very interesting life.
