What does live in infamy mean?

"Live in infamy" refers to a state of being remembered for disgraceful or shameful actions. The phrase is famously associated with Franklin D. Roosevelt's speech following the attack on Pearl Harbor, where he declared December 7, 1941, as a day that would "live in infamy." In this context, it signifies the lasting negative legacy of an event or individual that is marked by dishonor or infamy.
