Verified step by step guidance1
Zacharias Janssen is credited with inventing the compound microscope in the late 16th century, which was a significant advancement in the field of microscopy.
The compound microscope invented by Janssen used multiple lenses to achieve greater magnification compared to simple microscopes, which typically used a single lens.
Anton van Leeuwenhoek, known for his pioneering work in microbiology, utilized microscopes to observe microorganisms, such as bacteria, which were not visible to the naked eye.
The advancements in microscope technology, initiated by Janssen's invention, provided the necessary tools for Leeuwenhoek to make his groundbreaking discoveries.
Janssen's contribution laid the foundation for future developments in microscopy, enabling scientists like Leeuwenhoek to explore and understand the microscopic world in greater detail.
