Msgr. Lemaitre used many calculating machines to support his work including the Moon Hopkins (Burroughs série M), an accounting machine he diverted to compute differential equations for cosmology. An exemplar is visible in our museum and the original is exposed in his Alma Mater UCLouvain (at that time in Leuven)
