Barry Windsor-Smith was born in the United Kingdom. He was recruited by Marvel Comics for a test-period following work they saw from him in the UK. Although grateful for the opportunity, these where difficult times for him since he had to move to America with a visum and could only stay a limited time. Besides this, his rented apartment was not ready. This caused Barry to have to draw his first pages of Uncanny X-men in a park and on a tight schedule. Due to the work-conditions, this was not Barry's best work but Marvel had faith in him and he was soon contracted to do many other projects for Marvel. He became famous for his work on Conan and the Uncanny X-Men at Marvel. Later, in the 1990's, Windsor-Smith made his mark in the Valiant universe drawing some key issues and all the covers for the first half of the Unity crossover.
