Lazzaro Spallanzani

Lazzaro Spallanzani (1729–1799) was an Italian priest and scientist known for his pioneering work in biology and experimental philosophy. He conducted groundbreaking experiments that demonstrated that microorganisms do not spontaneously generate but instead come from existing life forms, helping to challenge the idea of spontaneous generation. Spallanzani also studied reproduction, animal development, and the digestive system, using methods that laid the groundwork for future scientific studies. His meticulous experiments and emphasis on observation were crucial in advancing the scientific method and enhancing our understanding of biology during the 18th century.
