The authors widen the horizon of inquiry by looking beyond the scientific elite of academies and prestigious science sponsored by princely courts, the focus of previous major studies of this time period. They consider people of diverse professions and occupations who advanced scientific knowledge through practical means by devoting their spare time and personal resources, thereby crossing geographic, linguistic and societal barriers. The case studies together demonstrate that such individuals contributed substantially to the spread of new knowledge and found ways to contribute technical innovations to society. The present volume is devoted to these people: the devotees of science.
