When did Joseph Jackson Lister fond that using several weak lenses allowed large magnifications without blurry images?

Joseph Jackson Lister discovered that using multiple weak lenses could achieve high magnification without sacrificing image clarity in the mid-19th century, specifically around the 1830s. This innovation greatly contributed to the development of modern compound microscopes, enhancing their optical performance. His work laid the foundation for advancements in microscopy, allowing for more detailed observations in biological and material sciences.
