Born and raised in the small town of Maldon, Essex and educated at Fettes College in Edinburgh, Brian was a shy and studious youth, living a relatively quiet life and spending a lot of time with his parents and siblings (older brother Jamie and fraternal twin Betsy). The family was an aristocratic one that was no longer rich enough to fraternise with their former academic peers, leaving Brian (too proud to fraternise with lower classes) a lonely child who immersed himself in the study of physics.
