Galvanis discovery, 1780 (1894)
Galvanis discovery, 1780 (1894). Italian physiologist Luigi Galvani experimenting on frogs. A professor working in Bologna, Galvani (1737-1798) performed experiments to investigate the behaviour of muscles stimulated by electricity. Whilst investigating the effects of electrostatic stimuli applied to the muscles of frogs, Galvani discovered he could make a muscle twitch by touching the nerve with metal (a pair of scissors for example) without a source of electrostatic charge. He called this phenomenon animal electricity. The term galvanise - to shock or excite into action, takes its name from him. From A Popular History of Science, by Robert Routledge, BSc (Lond.), F.C.S. [George Routledge & Sons, Limited. London, 1894]. (Colorised black and white print)

EDITORS COMMENTS
This print captures the groundbreaking moment in scientific history when Italian physiologist Luigi Galvani made his remarkable discovery in 1780. In this image, we see Galvani engrossed in his experiment, delicately working with a frog to investigate the behavior of muscles stimulated by electricity. As a professor based in Bologna, Galvani dedicated himself to unraveling the mysteries of muscle movement. It was during his exploration of electrostatic stimuli applied to frog muscles that he stumbled upon an extraordinary phenomenon. He found that simply touching the nerve with metal, such as a pair of scissors, could make the muscle twitch without any external source of electrostatic charge. This incredible revelation led him to coin the term "animal electricity". Galvani's groundbreaking work not only revolutionized our understanding of biology and physiology but also left an indelible mark on language itself. The word "galvanize" meaning to shock or excite into action, owes its origin to this brilliant scientist. The colorized print transports us back to this pivotal moment in science history during the late 18th century. It serves as a testament to Galvani's tireless pursuit of knowledge and highlights his significant contribution towards shaping our understanding of bioelectricity. This fascinating image is sourced from A Popular History of Science by Robert Routledge (1894), showcasing both artistry and scientific curiosity intertwined within one frame.
