Dan Johnson has posted his August 2001 white paper on Medical Enterprises and Open Source:
‘We in the health care industry, both software vendors and institutions, need to share code that meets common needs, and work together to develop it. We are wasting precious resources competing with duplicated effort. To share development of code that meets shared needs will spread R & D across the whole industry, and enhance useful competition to meet the individual needs of customers and to provide highest quality service…’ Dan is arguably the patriarch of free/open source software in medicine since he is the author of the earliest known writings (~1986) 1, 2, on the subject.
