>>>I thought it was kennedy who changed things as the first president to go out in public without a hat?>>>
You’re right.
I've heard that story too, but I just searched and the only pictures I googled of Ike that had a hat were from the military or playing golf.
Youre right.
You are both wrong. It is a nice myth but I grew up in the 1950s and hats were already dying out even then. All the men in the movies wore suits and hats but real life men didn't. Some men wore hats but most of them didn't wear a hat as an item of dress apparel. Kennedy may have helped finish the hat off but it was already going away by the time he was elected.
