The person who made the discovery of using multiple weak lenses to achieve high magnification without blurry images was Joseph Jackson Lister, not Josph Jackson Lister.

However, the year you are asking about is 1826. This is when Joseph Jackson Lister, an English wine merchant and amateur scientist, made his crucial discovery. He realized that by using multiple weak lenses, he could create a compound microscope that achieved higher magnification with less distortion than single lenses.

This discovery revolutionized the field of microscopy and led to the development of modern compound microscopes.
