Inspired by a boy who came into his confectionery shop
and couldn’t decide between chocolate and ice cream,
Christian  K. Nelson combines the two, receiving a 
patent for the Eskimo Pie—originally marketed as
"I-Scream" bars.
     

      
it became a nationwide sensation, with 1922 sales
averaging one million units a day and earning Nelson
$2,000 daily in royalties.  
   

Thanks to President Reagan, we celebrate National Ice Cream
Day every third Sunday in July, meaning July 18 this year. The
President wanted to commemorate a treat enjoyed by over 90
percent of the US population. In 1984, he decreed a day for ice
cream, and his proclamation actually glorified the dairy industry
in America. In fact, Americans still lead the world when it comes
to eating this frozen delight: 23 gallons a year to be precise.

Ron & Nancy Reagan enjoy ice cream cones in the Summer
of 1967.
