I want to know the answer to the following question:
What year was the Toepler Pump invented?
All the background I'm provided with is that "In 1654, Otto von Guericke invented the first vacuum pump and conducted his famous Magdeburg hemispheres experiment, showing that teams of horses could not separate two hemispheres from which the air had been partially evacuated.". Is that enough to answer the question?
Answer: no
