Important Catholic Scientists of the Past
It is our hope that these biographies will be useful to teachers, students, and the general public.
– Stephen M. Barr and Andrew Kassebaum
In Preparing This Curated Set of Biographies, We Have Striven to Satisfy Five Criteria
Include only scientists for whom we have found clear and reliable evidence that they were believing and practicing Catholics.
Include only scientists who made important contributions or breakthroughs.
Explain in a broadly accessible way what makes each of these scientists important in the history of science.
Make the biographies brief, readable, and concise (they average about 300 words).
Make the biographies historically accurate and balanced.
