The first basic cooler was a tub made of cedar with a tin tub inside. Ice was placed between the cedar and tin and then wrapped in rabbit fur. It was made by Thomas Moore who wanted a way to make his butter into a solid so he could sell it. Other versions were packed with straw or cork and lined with zinc or another material. And before that, people used rivers and other cold flowing water during the summer and packed in a snow-filled hole in the winter.
