## Summary
Conrad Gessner (1516–1565) was a Swiss physician, bibliographer, and naturalist renowned for his pioneering work in systematic bibliography and natural history. His most significant achievement was the creation of *Bibliotheca universalis* (1545–1549), a comprehensive catalog of all known books printed in Latin, Greek, or Hebrew, which laid the foundation for modern bibliographic practices. Gessner's interdisciplinary contributions spanned medicine, botany, zoology, and linguistics, making him a key figure in the Renaissance scientific revolution.
