It is well known that Swammerdam was born in Amsterdam as the son of an apothecary. He studied medicine at Leiden before travelling to France between 1663 and 1665. The roots of his studies can be found in the astonishing interests of his father. In Paris (as a guest of his friend Steno) his father Jan collected and described numerous insects. Besides that, he took part in famous debates on Cartesian approach to philosophy. His love and dedication for entomology and logical speculations influenced young Swammerdam who decided to became a scientist from an early age.
