1625: Giovanni Faber of Bamberg (1574–1629) of the Linceans, after seeing Galileo's occhiolino, coins the word microscope by analogy with telescope. 1655: In an investigation by Willem Boreel, Dutch spectacle-maker Johannes Zachariassen claims his father, Zacharias Janssen, invented the compound microscope in 1590. Zachariassen's claimed ...
Zacharias Janssen; also Zacharias Jansen or Sacharias Jansen; 1585 – pre-1632 [1]) was a Dutch spectacle-maker who lived most of his life in Middelburg.He is associated with the invention of the first optical telescope and/or the first truly compound microscope, but these claims (made 20 years after his death) may be fabrications put forward by his son.

Antonie van Leeuwenhoek (1632–1723). The field of microscopy (optical microscopy) dates back to at least the 17th-century.Earlier microscopes, single lens magnifying glasses with limited magnification, date at least as far back as the wide spread use of lenses in eyeglasses in the 13th century [2] but more advanced compound microscopes first appeared in Europe around 1620 [3] [4] The ...

Nonetheless, science and technology in England continued to develop rapidly in absolute terms. Furthermore, according to a Japanese research firm, over 40% of the world's inventions and discoveries were made in the UK, followed by France with 24% of the world's inventions and discoveries made in France and followed by the US with 20%.

Spencer Microscope: Brass and glass, made circa 1849-1859 by C. A. & H. Spencer, Canastota, NY USA Spencer’s first microscopes were available for purchase in 1838. [ 2 ] Previous to Spencer’s invention, European manufacturers held a monopoly on research-quality microscopic equipment. [ 3 ]
However, modern mathematicians generally believe that his axioms were highly incomplete, and that his definitions were not really used in his proofs. 300 BC: Finite geometric progressions are studied by Euclid in Ptolemaic Egypt. [43] 300 BC: Euclid proves the infinitude of primes. [44] 300 BC: Euclid proves the Fundamental Theorem of Arithmetic.
