The greatest obstacle to discovery is not ignorance – it is the illusion of knowledge.
– Daniel J. Boorstin, American historian
When trainee specialist Dr Barry Marshall first met with Dr J. Robin Warren, a staff pathologist at the Royal Perth Hospital, he had no idea that their collaboration and dogged persistence would eventually change a core belief of the medical profession and save half-a-million lives a year – each year, for ever – and for him to become a Nobel laureate.
