For more than 200 years, the U.S. Patent and Trademark Office has been recording all patents. I got lost for hours on the National Archives‘ site looking at inventions such as Alexander Graham Bell’s telephone and Thomas Edison’s electric lamp. These curious patent drawings from the 19th century just go to show how wicked inventive and creative some people were. Fascinating!
