Who discovered the electron microscope?

It was Ernst Ruska and Max Knoll, a physicist and an electrical engineer, respectively, from the University of Berlin, who created the first electron microscope in 1931. This prototype was able to produce a magnification of four-hundred-power and was the first device to show what was possible with electron microscopy.

1933, Ernst Ruska developed on the original model further to develop an electron microscope that was capable of producing an image of higher resolution than what was possible with optical microscopy. In 1937, Bodo von Borries and Helmut Ruska joined him to develop ways that the principles could be applied, such as to examine biological samples. In the same year, Manfred von Ardenne developed the first scanning electron microscope.

In 1986, Ernst Ruska was awarded the Nobel Prize in Physics for the invention of the electron microscope, in conjunction with Heinrich Rohrer and Gerd Binnig for the development of the scanning tunneling microscope (STM)

They did not discover it, they invented it.

Suzanne Wilson

"Discovered" suggests it was just hanging around waiting for someone to come into the room and spot it. I think "invented" or "developed" would have been more appropriate.

“How did you didsover the electron microscope?” “Well, I just peeked under a cabbage leaf, and, voila! There it was! Who’d a thunk it?”

David Lamoreaux

Badly worded question!

Special Patrol Group, The word “who” is an interrogative pronoun or a “question word” which cannot be used to indicate singularity or plurality.

Jim Moser

They did not discover it in a deep dark forest somewhere or under a rock or in a cave. They invented, designed and developed it!!

Kevin Dale Streets

"Discovered?" That must mean that someone else must have invented it, then hid all the specs for someone else to "discover" and "create!"

Chris Brown

As others have stated: invented or developed, - not discovered.

Louella Wilson

Special Patrol Group, you need to refresh your usage of grammar! "If you can replace the word with he or she or another subject pronoun, use WHO. If you can replace it with him or her (or another object pronoun), use WHOM."

Ken Putnam

As YOUR reference says, they CREATED it

I have no patience for people who have difficulty answering simple questions. I don't want to say how I feel about people who can't even properly ASK simple questions.
