PersonData by itself not working as expected

[rkonar (Rafal Konarzewski)]

Why it doesn’t work: PersonData[“John F. Kennedy”, “BirthDate”],
Thanks in advance!

try:

PersonData[Interpreter["Person"]["John F Kennedy"],"BirthDate"]

The problem was that the name was not in standard form. You can also use the inline Wolfram Alpha command:

As far as I can see, both work.
