GENBIOLOGY History Flashcards
History of Microscope
(1590) Hans and Zaccharias Janssen
Created the first microscope
Decided to improve the microscope design by converting one of his telescope
(1624) Galileo Galilei
Coined the term “Microscope” device that enlarges small objects invisible to the naked eye.
(1625) Giovanni Faber
What is the first microscope?
Compound Microscope
-Coined the term “CELLS” when describing the structure of cork under the microscope.
(1665) Robert Hooke
Created microscope with 3 biconvex lenses that could magnify objects 30x more
(1624) Galileo Galilei
published “Micrographia” which detailed hundred of specimen he was able to observed using a microscope.
(1665) Robert Hooke
He improved the microscope by making a groundbreaking discovery that would forever change the heath science.
(1667) Antonie Van Leeuwenhoek
Look at the fabric he is selling, he decided to take a closer look at it.
(1667) Antonie Van Leeuwenhoek
HE discovered bacteria by using Single lens Microscope
(1667) Antonie Van Leeuwenhoek
He is considered “Father of bacteriology”
(1667) Antonie Van Leeuwenhoek
Discovered that by combining weak lenses in a specific way, you could improve image resolution and eliminate chromatic and spherical aberrations
(1800) Joseph Jackson Lister
uses mathematics surrounding the wavelength of light.
(1878) Ernst Abbe and Carl Zeiss
-Invented the “Ultramicroscope”
(1903) Richard Zsigmondy
He discovered that resolution was related to diffraction today that is known as Abbe’s Theory
(1878) Ernst Abbe and Carl Zeiss
Instead of light. He invented a microscope that is powered by electrons.
(1931) Ernst Raska
Invented a 27 million dollar microscope with a resolution of half-Angstrom or 300 billionths of a foot.
(2008) Lawrence Berkeley National Laboratory
Microscope -powered by electrons
Transmission Electron Microscope (TEM)
Created the atomic-resolution environmental transmission electron microscope (ETEM)
(2009) Pratibha Gai
-Can track single proteins as they assemble within cells.
(2014) Super resolution fluorescence microscopy
