No... That's not true. You're off by over one hundred years for the Western world. The UK passed the Cruelty to Animals act in 1876

https://en.wikipedia.org/wiki/Cruelty_to_Animals_Act,_1876

The act states that:

> "Researchers would be prosecuted for cruelty, unless they conformed to its provisions, which required that an experiment involving the infliction of pain upon animals to only be conducted when "the proposed experiments are absolutely necessary for the due instruction of the persons [so they may go on to use the instruction] to save or prolong human life"

It also contains punishments for not giving animals anesthestia, which is a ridiculous waste of resources if "people didn't even think animals felt pain until the 1980s."
