Savor Tonight claims:
During WWI, the US Gov’t tried to rename hamburgers as ‘liberty sandwiches.’
I've found this claim on several other websites, too.
This is definitely a case where Wikipedia fails to be a good source. It claims:
During World War II, waves of anti-German sentiment inspired some to refer to hamburgers as "liberty sandwiches."
Note the discrepancy between WW1 and WW2. The cited source was an article in The Chive about WW2.
Hamburgers were renamed “Liberty Steaks” in order to avoid the German-sounding name for a brief period of time.
Note the discrepancy between "sandwiches" and "steaks". The Chive doesn't give a source.
The inconsistency between articles and the poor referencing has all the signs of a claim that is untrue. It is also similar to freedom fries, which has a basis in truth, so the claim is remotely believable.
Did the U.S. government ever make an effort to change the name of hamburgers to "liberty sandwiches" or "liberty steaks"?
