Athanasius Kircher: Biography, Achievements & Lasting Legacy

Kircher's work in geology included studies of volcanoes and fossils. One of the first researchers to observe microbes through a microscope, Kircher was ahead of his time in proposing that the plague was caused by an infectious microorganism and in suggesting effective measures to prevent its spread. Kircher also displayed a keen interest in technology and mechanical inventions; inventions attributed to him include a magnetic clock, various automatons and the first megaphone. The invention of the magic lantern has been misattributed to Kircher, although he conducted a study of the principles involved in his Ars Magna Lucis et Umbrae.

A scientific star in his day, towards the end of his life he was eclipsed by the rationalism of René Descartes and others. In the late 20th century, however, the aesthetic qualities of his work again began to be appreciated. One modern scholar, Alan Cutler, described Kircher as "a giant among seventeenth-century scholars", and "one of the last thinkers who could rightfully claim all knowledge as his domain". Another scholar, Edward W. Schmidt, referred to Kircher as "the last Renaissance man". In A Man of Misconceptions, his 2012 book about Kircher, John Glassie wrote "many of Kircher's actual ideas today seem wildly off-base, if not simply bizarre," but he was "a champion of wonder, a man of awe-inspiring erudition and inventiveness," whose work was read "by the smartest minds of the time."
