Buffalo fur coats and robes were a stylish way to keep warm in the late 1800s and early 1900s, especially during winter travel. However, Buffalo fur coats were expensive.
Imitation buffalo fur was a popular and less expensive alternative. John Morley from Waterloo invented his own process of treating wool to create imitation buffalo fur.
Manufacturing processes, or the method of making a product, are often patented just as often as products themselves are patented.
