Lazzaro Spallanzani (Italian pronunciation: [ˈladdzaro spallanˈtsaːni]; 10 January 1729 – 12 February 1799) was an Italian Catholic priest, biologist and physiologist who made important contributions to the experimental study of bodily functions, animal reproduction, and animal echolocation. His research of biogenesis paved the way for the downfall of preformationism theory (the idea that organisms develop from miniature versions of themselves), though the final death blow to preformationism was dealt by Pasteur.

Spallanzani was born in Scandiano in the modern province of Reggio Emilia and died in Pavia, Italy. He was educated at the Jesuit College and started to study law at the University of Bologna, which he gave up soon and turned to science. Here, his famous kinswoman, Laura Bassi, was professor of physics and it is to her influence that his scientific impulse has been usually attributed. With her he studied natural philosophy and mathematics, and gave also great attention to languages, both ancient and modern, but soon abandoned them.

In 1754, at the age of 25 he became professor of logic, metaphysics and Greek in the University of Reggio. In 1762 he was ordained as a priest, 1763 he was moved to Modena, where he continued to teach with great assiduity and success, but devoted his whole leisure to natural science. He declined many offers from other Italian universities and from St Petersburg until 1768, when he accepted the invitation of Maria Theresa to the chair of natural history in the University of Pavia, which was then being reorganized. He also became director of the museum, which he greatly enriched by the collections of his many journeys along the shores of the Mediterranean Sea. In June 1768 Spallanzani was elected a Fellow of the Royal Society and in 1775 was elected a foreign member of the Royal Swedish Academy of Sciences.
